A students received a score of 50 on his history test. The test had a mean of 69 and a standard deviation of 10. Find the z score and assess whether his score is considered unusual.

Answers

[tex]z = \frac{x - mean}{stdev} \\ \\ z = \frac{50 - 69}{10} = -1.9[/tex]

The general rule is that 68% of all scores are within 1 z-score of the mean.
95% are within 2 z-scores of the mean.
99% are within 3 z-scores of the mean.

1.9 is pretty close to 2, so this means approximately only 5% of all scores are more unusual than this students' score.

Bailey writes the expression g2 + 14g + 40 to represent the area of a planned school garden in square feet. If g = 5, what are the dimensions of the school garden? 20 feet by 2 feet 10 feet by 4 feet 12 feet by 7 feet 15 feet by 9 feet

Answers

To solve this, you need to plug in your solution to your variable.

g² + 14g + 40

5² + 14(5) + 40

25 + 70 + 40

So, your area would be 135. 

Out of your 4 options, you need to find out which dimensions create 130.

20 × 2 = 40
4 × 12 = 48
12 × 7 = 84
15 × 9 = 135

Your dimensions are 15ft by 9ft :)

Hope this helps!

g^2 14g+40

replace g with 5

5^2 +14(5) +40 = 25 + 70 +40 = 135 square feet

Area =L x W

 using your choices multiply 15 x 9 = 135

 so answer is 15 feet by 9 feet

I need help with simplifying this question
43+a-2a
Thank you!!!!

Answers

The answer is 43 - a 
(Hope this helps you!)

The correct answer is 43-a. In other words, the result of simplifying algebraic expressions 43 + a - 2a is 43 - a.

To simplify the expression 43 + a - 2a, you can combine like terms.

The expression consists of three terms: 43, a, and -2a.

Starting with the numbers, 43 is a constant term and does not contain any variables. Since there are no other terms with numbers, 43 remains unchanged.

Next, let's simplify the terms with variables. We have a and -2a. To combine these terms, we can group them together as a single term.

The term with a is positive a, and the term with -2a is negative 2a. When we combine them, we subtract 2a from a. This gives us a - 2a, or -a.

Therefore, the simplified expression is 43 - a.

Therefore, the correct answer is 43-a. In other words, the result of simplifying algebraic expressions 43 + a - 2a is 43 - a.

For a normal population with a mean of m = 80 and a standard deviation of s = 10, what is the probability of obtaining a sample mean greater than m = 75 for a sample of n = 25 scores? p = 0.0062 p = 0.9938 p = 0.3085 p = 0.6915

Answers

The calculated z-score is -2.5, and the corresponding probability is 0.9938, meaning there is a 99.38% chance of drawing a sample with a mean greater than 75.

To find the probability of obtaining a sample mean greater than m = 75 for a sample of n = 25 scores when the population mean is m = 80 and the standard deviation is s = 10, we will use the concept of sampling distributions and the Central Limit Theorem.

First, we need to calculate the standard error of the mean (SEM), which is the standard deviation of the sampling distribution of the sample mean.

The SEM is calculated using the formula [tex]SEM = s / \sqrt{n[/tex] where s is the population standard deviation and n is the sample size.

Here, SEM = [tex]10 / \sqrt{25[/tex]

= 10 / 5

= 2.

Next, we convert the sample mean to a z-score to find out how many standard errors the sample mean is from the population mean.

The z-score is calculated using the formula z = (M - m) / SEM, with M being the sample mean and m the population mean.

Therefore, z = (75 - 80) / 2 = -5 / 2 = -2.5.

Looking at the standard normal distribution table or using statistical software, we find that the probability associated with a z-score of -2.5 is approximately 0.9938. This means that the probability of obtaining a sample mean greater than 75 is 0.9938.

Emma is scrapbooking she has 9 inches of paper and needs to cut it into 2/5 inch strips of paper how many strips will she be able to make

Answers

First off it would be 9 divided by 2/5.
Then by using the reciprocal, multiply them both (change 9 to 9/1)

9/1 x 5/5 = 45/2

If you would like to convert it, it would be 22 1/2

Answer:

22 strips.

Step-by-step explanation:

In order to solve this you just have to divide the total inches of paper that she actually has by the size of the strips that she´s going to make:

[tex]9 inches/2/5\\\frac{ 9inches}{\frac{2}{5} } \\\frac{45}{2}\\22\frac{1}{2}[/tex]

So as you can see she can make a total of 22 strips and a half, but the half won´t be useful so she can make 22 strips.

If one of the purple-flowered progeny plants is selected at random and self-fertilized, what is the probability it will breed true? if one of the purple-flowered progeny plants is selected at random and self-fertilized, what is the probability it will breed true? 2/3 3/4 1/4 1/3

Answers

This is in reality a biology question given a lot of biology related information is not given in the problem.
However, I will provide the answer by making biology-related assumptions.
1. The genotype of the purple-flowered progeny is Pp
2. The purple-flower phenotype is recessive.

If self fertilized, both "parents" have genotype Pp
The punnett square is as follows:

         P      p
P     PP    Pp
p     Pp     pp

Since purple-flowers are recessive, only PP will come out purple, hence the probability is 1/4.

Initially, a store has 35 train sets. The store sells 3 train sets each month.

What is the explicit rule for the number of train sets the store has after ‘n’ months?

Answers

The explicit rule is t=35-3(n)
Final answer:

The explicit rule for the remaining train sets after 'n' months is represented by the formula T(n) = 35 - 3n, where T(n) is the total number of train sets, and 'n' is the number of months.

Explanation:

The explicit rule for the number of train sets a store has after ‘n’ months, given that the store starts with 35 train sets and sells 3 each month, can be represented by a linear equation. The initial amount of train sets is the starting point, and the number of sets sold each month is the rate of change.

The explicit rule for the number of train sets the store has after 'n' months can be represented by the linear function:

\[ T(n) = 35 - 3n \]

Here, \( T(n) \) represents the number of train sets after 'n' months, 35 is the initial number of train sets, and 3n represents the number of train sets sold each month. The negative coefficient (-3) indicates the decrease in the number of train sets each month. By plugging in different values for 'n', you can determine the number of train sets the store will have at any given month.

This is reflected in the equation:

T(n) = 35 - 3n

where T(n) represents the total number of train sets after n months, and n is the number of months that have passed.

Answers

Final answer:

To calculate the probability that at least 150 individuals will cooperate and respond to the questions in a new sample of 400 telephone numbers with a historical response rate of 44%, we use the binomial distribution formula.

Explanation:

To calculate the probability that at least 150 individuals will cooperate and respond to the questions, we need to use the binomial distribution formula. The formula is:

P(X ≥ k) = 1 - P(X

Where n is the sample size, k is the desired number of successes, p is the historical response rate, q = 1 - p is the failure rate.

In this case, n = 400, k = 150, p = 0.44, q = 1 - 0.44 = 0.56. Plugging these values into the formula, we get:

P(X ≥ 150) = 1 - P(X<150)

We can use a software or calculator to evaluate this expression. The probability is approximately 0.9328 to 4 decimal places.
