If the textbook receives a favorable​ review, what is the probability that it will be huge​ success?

Answers

Answer 1

Answer:

34.86% probability that it will be huge​ success

Step-by-step explanation:

Bayes Theorem:

Two events, A and B.

[tex]P(B|A) = \frac{P(B)*P(A|B)}{P(A)}[/tex]

In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.

In this question:

Event A: Receiving a favorable review.

Event B: Being a huge success.

Information on previous textbooks published show that 20 % are huge​ successes

This means that [tex]P(B) = 0.2[/tex]

99 % of the huge successes received favorable​ reviews

This means that [tex]P(A|B) = 0.99[/tex]

Probability of receiving a favorable review:

20% are huge​ successes. Of those, 99% receive favorable reviews.

30% are modest​ successes. Of those, 70% receive favorable reviews.

30% break​ even. Of those, 40% receive favorable reviews.

20% are losers. Of those, 20% receive favorable reviews.

Then

[tex]P(A) = 0.2*0.99 + 0.3*0.7 + 0.3*0.4 + 0.2*0.2 = 0.568[/tex]

Finally

[tex]P(B|A) = \frac{P(B)*P(A|B)}{P(A)} = \frac{0.2*0.99}{0.568} = 0.3486[/tex]

34.86% probability that it will be huge​ success

Major Motors produces its Trans National model in three plants located in Flint, Michigan; Fresno, California; and Monterrey, Mexico. Dealers receive cars from regional distribution centers located in Phoenix, Arizona; Davenport, Iowa; and Columbia, South Carolina. Anticipated production at the plants over the next month (in 100s of cars) is 43 at Flint, 26 at Fresno, and 31 at Monterrey. Based on firm orders and other requests from dealers, Major Motors has decided that it needs to have the following numbers of cars at the regional distribution centers at month’s end: Phoenix, 26; Davenport, 28; and Columbia, 30. Suppose that the cost of shipping 100 cars from each plant to each distribution center is given in the following matrix (in $1,000s):

Answers

Answer:

See attached image for a balanced one by adding a row

Final answer:

The question involves converting an unbalanced transportation problem for Major Motors into a balanced one and solving it using the Greedy Heuristic. It requires adding a dummy destination with zero shipping cost and then allocating the supply to demand sites starting from the lowest shipping costs.

Explanation:

The student's question pertains to creating a balanced transportation problem from the given unbalanced scenario involving Major Motors and using the Greedy Heuristic to find a solution. The three plants located in Flint, Fresno, and Monterrey have production capacities of 43, 26, and 31 (in hundreds of cars) respectively, and the distribution centers in Phoenix, Davenport, and Columbia have requirements of 26, 28, and 30 (in hundreds of cars) respectively.

First, we need to balance the problem by equating total supply with total demand. The total supply from all plants is 43 + 26 + 31 = 100 (in hundreds of cars), and the total demand from all distribution centers is 26 + 28 + 30 = 84 (in hundreds of cars). We will need to add a dummy distribution center with a demand of 16 (in hundreds of cars) to balance the problem, with zero shipping cost to this dummy destination from all plants. Now, we apply the Greedy Heuristic, which involves selecting the lowest cost choices first and fulfilling demand as supply allows.

We start by assigning cars to the distribution centers from the cheapest shipping options available. Let's illustrate a step, shipping from Flint to Columbia as it has the lowest cost of $7,000 for 100 cars. Continuing this process until all demands are met will provide us with an approximate solution to the transportation problem.

Suppose that the population of the scores of all high school seniors that took the SAT-M (SAT math) test this year follows a normal distribution with unknown population mean and known standard deviation 100. You read a report that says, "On the basis of a simple random sample of 100 high school seniors that took the SAT-M test this year, a confidence interval for population mean is 512.00 ± 25.75." The confidence level for this interval is

Answers

Answer:

[tex] 25.75 = z_{\alpha/2} \frac{100}{\sqrt{100}}[/tex]

And solving for the critical value we got:

[tex] z_{\alpha/2}= \frac{25.75*10}{100} = 2.575[/tex]

Now we need to find the confidence level and for this case we can use find this probability:

[tex] P(-2.575< Z<2.575)= P(Z<2.575) -P(Z<-2.575)[/tex]

And using the normal standard distribution or excel we got:

[tex] P(-2.575< Z<2.575)= P(Z<2.575) -P(Z<-2.575)= 0.9950-0.0050= 0.99[/tex]

So then the confidence interval for this case is 99%

Step-by-step explanation:

For this case the random variable X is the scores for the SAT math scores and we know that the distribution for X is normal:

[tex] X\sim N(\mu , \sigma =100)[/tex]

They select a random sample of n =100 and they construc a confidence interval for the true population mean of interest and they got:

[tex]512.00 \pm 25.75[/tex]

for this problem we need know that the confidence interval for the true mean when the deviation is known is given by:

[tex]\bar X \pm z_{\alpha/2}\frac{\sigma}{\sqrt{n}}[/tex]

The margin of error is given by:

[tex] ME =z_{\alpha/2} \frac{\sigma}{\sqrt{n}}[/tex]

And the margin of error for this interval is [tex] ME = 25.75[/tex] then we can solve for the critical value in order to find the confidence level:

[tex] 25.75 = z_{\alpha/2} \frac{100}{\sqrt{100}}[/tex]

And solving for the critical value we got:

[tex] z_{\alpha/2}= \frac{25.75*10}{100} = 2.575[/tex]

Now we need to find the confidence level and for this case we can use find this probability:

[tex] P(-2.575< Z<2.575)= P(Z<2.575) -P(Z<-2.575)[/tex]

And using the normal standard distribution or excel we got:

[tex] P(-2.575< Z<2.575)= P(Z<2.575) -P(Z<-2.575)= 0.9950-0.0050= 0.99[/tex]

So then the confidence interval for this case is 99%

Write her test score as a percent

Answers

Final answer:

Maria's test score is calculated by dividing the number of correct answers (22) by the total number of questions (25) and then multiplying by 100, resulting in a score of 88%.

Explanation:

Maria took a history test with 25 questions and correctly answered 22 questions. To find her test score as a percent, you divide the number of correct answers by the total number of questions and then multiply the result by 100. So, Maria's score would be (22 correct answers / 25 total questions) × 100 = 88%.

This is how it calculates:

First, write the number of correct answers over the total number of questions as a fraction: 22/25.

Then, convert this fraction to a decimal by dividing 22 by 25, which equals 0.88.

Finally, multiply the decimal by 100 to get the percentage. So, 0.88 × 100 equals 88%.

Maria's test score expressed as a percent is 88%.

What is the exact value of cot (3 pi/4) ?

Answers

The exact value of cot(3π/4) is 1.

What is Cotangent ?

Cotangent (cot) is defined as the ratio of the adjacent side to the opposite side of a right triangle. In the case of 3π/4, which is a 45-degree angle in the third quadrant, we can use the reference angle of π/4 (45 degrees in the first quadrant) to find the corresponding values.

In the first quadrant, the tangent of π/4 is 1, meaning the opposite side is equal to the adjacent side. In the third quadrant the values are negated, so the opposite side becomes -1, and the adjacent side becomes -1.

Therefore, cot(3π/4) can be calculated as the ratio of the adjacent side (-1) to the opposite side (-1), resulting in:

cot(3π/4) = -1/-1 = 1.

So, the exact value of cot(3π/4) is 1.

On a coordinate plane, a parallelogram has points (16, 4), (10, 1), (2, 1), (8, 4).

The base is 6 and the height is 3, so the area is 6 (3) = 18 square units.

The base is 8 and the height is 3, so the area is 8 (3) = 24 square units.

The base is 8 and the height is 4, so the area is 8 (4) = 32 square units.

The base is 8 and the height is 6, so the area is 8 (6) = 48 square units.

Answers

Answer:

The base is 8 and the height is 3, so the area is 8 (3) = 24 square units.

Step-by-step explanation:

The area of the parallelogram is given by the following expression:

The probability of not spinning a 5 and flipping heads

Answers

Final answer:

The probability of not spinning a 5 and flipping heads in a coin toss, assuming a spinner with 10 numbers and a fair coin, is 0.45 or 45%. This is calculated by multiplying the individual probabilities of each independent event.

Explanation:

The question asked is related to the concept of probability, which refers to the likelihood of an event occurring. Specifically, it involves two independent events: spinning a number (other than 5) on a spinner, and flipping a coin to get heads. In this case, the two events do not affect the outcomes of each other.

Let's assume the spinner has 10 numbers (1 to 10) and the coin is fair (meaning the probabilities of getting heads and tails are equal). The probability of not getting a 5 on the spinner is 9/10 (because 9 out of the 10 possible outcomes meet this criterion), and the probability of getting heads on a coin flip is 1/2 (because 1 out of the 2 possible outcomes meets this criterion)

Since these are independent events, we can use the rule of product in probability to calculate the combined probability by multiplying the individual probabilities: (9/10) * (1/2) = 9/20, or 0.45. So, the probability of both not spinning a 5 and flipping heads is 0.45, or 45%.

Final answer:

The student's question involves calculating the combined probability of independent events in a high school Mathematics context. It also touches on the law of large numbers, which predicts the long-term outcomes of random events. Additionally, the principles of entropy and orderliness in potential outcomes are discussed.

Explanation:

The question at hand deals with the concept of probability, specifically the likelihood of spinning a number other than 5 on a device, such as a spinner or die, and flipping a coin to get heads. When we assess the chance of getting either of these outcomes, if we presume each event to be independent, the combined probability is the product of their individual probabilities.

The statistical underpinning of this concept lies in the law of large numbers, which articulates that as the number of trials in a probability experiment increases, the observed or empirical frequency approaches the theoretical probability. This law reinforces why the outcomes of coin tosses and die rolls often do not match expected results exactly in small sample sizes but do over many repetitions.

Furthermore, when analyzing the microstate probabilities of coin tosses, we assume each result has an equal likelihood of occurring, which allows us to predict the macrostate frequencies. When tossing coins, we consider symmetrical outcomes such as 5 heads or 5 tails to be orderly and less likely than the more disorderly and common 3 heads with 2 tails.

Si se quiesiera agregar únicamente 2 salones más y una cancha de fútbol de 3/4 del terreno original que te tanto más de espacio se necesitaría en el nuevo terreno.?

Answers

Answer:

- 4 new classrooms can be built on the newly acquired plot.

- The number of classrooms on the first floor of the school's land = 8

- The amount of extra space on the new land needed to add just 2 more rooms and a soccer field 3/4 of the original land = 375 m²

Step-by-step explanation:

The current rectangular plot for the school has dimensions 50 m length and 12 m width.

The current school plot has an area of (50×12) that is, 600 m².

The newly acquired rectangular plot, is said to be (1/4) of the current plot.

Area of the newly acquired rectangular plot

= (1/4) × 600 = 150 m²

Each classroom on the current school's plot occupies (1/16) of the the current rectangular plot, area of a classroom on the current plot.

= (1/16) × 600 = 37.5 m²

So, how many classrooms can be obtained from the newly acquired rectangular plot?

Area of the newly acquired rectangular plot = 150 m²

Area of one classroom = 37.5 m²

Number of classrooms obtainable from the newly acquired rectangular plot = (150/37.5)

= 4 classrooms

b) The schoolyard is equal to 3/5 of the land. How many classrooms on the first floor does the school have?

Total area of school land now = 600 m² + 150 m² = 750 m²

Schoolyard occupies (3/5) of the space.

Then, the classrooms on the first floor will occupy (2/5) of the space.

Area occupied by classrooms = (2/5) × 750

= 300 m²

Recall, each classroom occupies 37.5 m² of space,

Hence, the number of classrooms on the first floor = (300/37.5) = 8 classrooms to the nearest whole number.

c) If you wanted to add just 2 more rooms and a soccer field 3/4 of the original land, so much more space would be needed in the new field?

2 more classrooms will occupy = 2 × 37.5 = 75 m²

(3/4) of the original land = (3/4) × 600 = 450 m²

Total new space required = 75 + 450 = 525 m²

The newly acquired rectangular plot has an area of 150 m², So, to achieve those two projects (add just 2 more rooms and a soccer field 3/4 of the original land) that would require 525 m².

The amount of extra space that will be required = 525 - 150 = 375 m²

Multiply the fractions and reduce to lowest terms: 16 x 5/9 x 2 1/2

Answers

Answer:

thee answer is 22.22 hopes this helps

To multiply fractions 16, 5/9, and 2 1/2 and reduce to lowest terms, convert mixed numbers to improper fractions, multiply the numerators and denominators, and then simplify by common factors. The reduced answer is 200/9.

To multiply the fractions and reduce to lowest terms of the expression 16 x 5/9 x 2 1/2, we first convert the mixed number to an improper fraction. The number 2 1/2 can be written as 5/2 because 2 x 2 + 1 = 5.

Now, we have the multiplication of three numbers, which is 16 x 5/9 x 5/2. Multiplying the numerators together and the denominators together, we get 16 x 5 x 5 in the numerator and 1 x 9 x 2 in the denominator, simplifying to 400/18.

To reduce this fraction to the lowest terms, we divide the numerator and the denominator by the greatest common divisor, which is 2. This gives us 200/9. The final answer cannot be reduced further, so the reduced fraction is 200/9.

A park has an area of 12.5 sq miles and a width of 5 miles. What is the perimeter of the park?

Step-by-step explanation:

12.5/5=2.5

2(2.5)+2*5=

5+10=15

Final answer:

To calculate the perimeter of the park with an area of 12.5 sq miles and a width of 5 miles, you divide the area by the width to get the length and then apply the formula P = 2(l + w). The perimeter of the park is 15 miles.

Explanation:

The question pertains to finding the perimeter of a park given its area and width. To find the perimeter, we need to know both the length and the width of the park. Since the area of the park is 12.5 sq miles and the width is 5 miles, we can find the length by dividing the area by the width, which gives us a length of 2.5 miles. Once we have both dimensions, we can use the formula for perimeter P = 2(l + w), where l is the length and w is the width.

Using the formula, the perimeter P = 2(2.5 miles + 5 miles) = 2(7.5 miles) = 15 miles. So, the perimeter of the park is 15 miles.

24/157 = 0.15

Ok, we now see that with the bigger option we obtained almost the same ratio (if we use the smaller values for X, we will get a ratio bigger than 0.15, so 0.15 is the better aproximation that we can find to the 0.14 of the 7-th graders)

Then the correct option is 4) 157

The number of right-handed graders should be option 4.

Calculation of the number of right-handed graders:

Since in 7th grade

We have

Left-handed: 11

Right-handed: 72

So, The ratio is = 11: 72 = 0.14

Now the ratio for the 8th grade should be the same

So,

Left-handed: 24

Right-handed: X

so,

Ratio: 24/X

Now

if we can do

[tex]24\div 157 = 0.15[/tex]

0.15 = 0.15

Therefore, the option 4 is correct.

Max has been offered positions by two car companies. The first company pays a salary of $12,500 plus commission of $1500 for each car sold. The second company pays a salary of $17,500 plus a commission of $500 per car sold. How many cars would need to be sold to make the total pay the same

Answers

Answer:

5 Cars

Step-by-step explanation:

Let the number of cars to be sold to make the total pay equal be x.

The first company pays a salary of $12,500 plus commission of $1500 for each car sold.

Algebraically written as: 12500+1500x

The second company pays a salary of $17,500 plus a commission of $500 per car sold.

Algebraically written as: 17500+500x

Equating both sides

12500+1500x=17500+500x

Collect like terms

1500x-500x=17500-12500

1000x=5000

Divide both sides by 1000

x=5

Therefore, when 5 cars are sold, the total pay would be the same.

Step-by-step explanation:

The stem-and-leaf plot corresponds to the data set {17, 27, 40, 46, 56, 60, 82, 88}.

What is a stem-and-leaf plot?

In this plot, the first digit is 'stem' and the last digit is a 'leaf'.

And this plot is used to describe the quantitative data.

The stem-and-leaf plot shows the first digit (the stem) of each data point followed by the second digit (the leaf) of each data point. For example, the first row of the plot shows a stem of 1 and two leaves of 7, which corresponds to the number 17 in the data set. Similarly, the second row shows a stem of 2 and a leaf of 7, which corresponds to the number 27 in the data set.

Therefore, the correct option is:

{17, 27, 40, 46, 56, 60, 82, 88}.

What are the zeros of the quadratic function f(x) = 2x2 + 16x – 9?
x= -4- and x = -4+
x=4 - 125 and x = 4+ / 25
x=-4-1 and x = 4+
• x= -4- and x = -4+

Answers

The zeros of the quadratic function f(x) = 2x² + 16x - 9 are obtained by using the quadratic formula, resulting in x = -4 + √{82} and x = -4 - √{82}.

To find the zeros of the quadratic function f(x) = 2x² + 16x - 9, we can either factor the quadratic, complete the square, or use the quadratic formula. The function provided is already in the standard form of a quadratic equation, ax² + bx + c = 0. For this equation, a = 2, b = 16, and c = -9.

To use the quadratic formula, x = (-b√{b² - 4ac}) / (2a), we substitute the values of a, b, and c into the formula:

x = (-(16) √{(16)² - 4(2)(-9)}) / (2(2))
x = (-16 √{256 + 72}) / 4
x = (-16 √{328}) / 4
x = (-16 √{82}) / 4
x = -4 √{82}

Therefore, the zeros of the function are x = -4 + √{82} and x = -4 - √{82}.

A study investigated whether price affects people's judgment. Twenty people each tasted six cabernet sauvignon wines and rated how they liked them on a scale of 1 to 6. Prior to tasting each wine, participants were told the price of the wine. Of the six wines tasted, two were actually the same wine, but for one tasting the participant was told that the wine cost $10 per bottle and for the other tasting the participant was told that the wine cost $90 per bottle. The participants were randomly assigned either to taste the $90 wine first and the $10 wine second, or the $10 wine first and the $90 wine second. Differences were calculated by subtracting the rating for the tasting in which the participant thought the wine cost $10 from the rating for the tasting in which the participant thought the wine cost $90.Difference ($90 − $10):3 , 4 ,2 ,2 , 1, 0, 0, 3, 0, 2, 1, 3, 3, 1, 4, 1, 2, 2, 1, −1Carry out a hypothesis test to determine if the mean rating assigned to the wine when the cost is described as $90 is greater than the mean rating assigned to the wine when the cost is described as $10. Use α = 0.01. (Use a statistical computer package to calculate the P-value. Use μ$90 − μ$10. Round your test statistic to two decimal places, your df down to the nearest whole number, and your P-value to three decimal places)

Answers

Final answer:

To determine if the mean rating assigned to the wine when the cost is described as $90 is greater than the mean rating assigned to the wine when the cost is described as $10, a hypothesis test is conducted.

Explanation:

To determine whether the mean rating assigned to the wine when the cost is described as $90 is greater than the mean rating assigned to the wine when the cost is described as $10, a hypothesis test is conducted. The null hypothesis assumes that the mean rating difference is not greater than zero, while the alternative hypothesis assumes that the mean rating difference is greater than zero.

A one-sample t-test is used, and the test statistic is calculated by dividing the mean difference of the ratings by the standard error. The degrees of freedom are determined by the sample size minus 1.

The resulting test statistic is compared to the critical value from the t-distribution with the given alpha level. If the test statistic is greater than the critical value, the null hypothesis is rejected, indicating that there is sufficient evidence to conclude that the mean rating assigned to the $90 wine is greater than the mean rating assigned to the $10 wine.

Answers

Answer:

c.systematic random sampling.

Step-by-step explanation:

Using sampling concepts, it is found that this type of sample is called systematic random sampling, which means that option c is correct.

How are samples classified?

Samples may be classified as:

Convenient: Drawn from a conveniently available pool.Random: All the options into a hat and drawn some of them.Systematic: Every kth element is taken. Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.Stratified: Also divides the population into groups. Then, a equal proportion of each group is surveyed.

In this problem, after the 1st person is surveyed, every kth person, with k = 5 is surveyed, hence it is a systematic random sampling and option c is correct.

answer to the nearest hundredth (2 decimal places). *


Answers

Answer: The required probability is 0.79

Step-by-step explanation:

Given: P(A) = 0.14

P(B) = 0.24

P(A and B) = 0.19

To find:  P(A given B)

The conditional probability of an event A is the probability that the event will occur given the knowledge of an already occurred event B and is denoted by

[tex]P(A/B)[/tex] or [tex]P(A \text { given } B)[/tex] where the value of [tex]P(A/B)= \dfrac{P(A \text { and } B)}{P(B)}[/tex]

So we have

[tex]P(A/B) = \dfrac{0.19}{0.24} \approx 0.79[/tex]

Hence ,the required probability is 0.79

Lera brought a watermelon that weighed b kg to a party. Nick brought a box of candies. How much is the weight of the box of candies greater than the weight of the watermelon if the weight of the watermelon is 2/5 of the weight of the box of candies?

Answers

Answer:

1.5b (kg)

Step-by-step explanation:

Let's begin by listing out the variables we were given:

weight of the watermelon = b (kg),

weight of watermelon = (2/5) * weight of candies

weight of candies = 1 ÷ (2/5) = 1 ÷ 0.4

weight of candies = 2.5b (kg)

How much is the weight of the box of candies greater than the weight of the watermelon is given by:

weight of the box of candies - weight of watermelon= 2.5b - b = 1.5b (kg)

Therefore, the weight of the box of candies is greater than the weight of the watermelon by 1.5b (kg)

MAKE SURE TO ADD ‘b’ AFTER THE 1.5. THEN YOU WILL GET CORRECT ANSWER!!!! Also, please mark BRAINLIEST!!!!

Answer: 1.5b

Step-by-step explanation:

b kg is the weight of the watermelon

(5/2)b kg is the weight of the box of candies

(5/2)b - b = (5/2 - 1)b = 1.5b

The weight of the box of candies is 1.5b kg greater than the weight of the watermelon.
