Find the 91st term of the arithmetic sequence 4,6,8

Answers

Answer:

184

Step-by-step explanation:

Find the common difference first   d = 6 - 4 = 2

first term  a_1  = 4

a_n = (n -1)*d + a_1

a_91 = (91 - 1) * 2 + 4

a_91  is the 91st term:

a_91 = 90*2 + 4

a_91 = 180 + 4 = 184

Final answer:

The 91st term of the arithmetic sequence 4,6,8 is 184.

Explanation:

The question requires us to find the 91st term of the arithmetic sequence 4,6,8. In an arithmetic sequence, each term is equal to the previous term plus a constant difference. In this case, the common difference is 2 (6-4 or 8-6).

To find the 91st term of an arithmetic sequence, we use the formula a + (n-1)d, where a is the first term, n is the term number, and d is the common difference. Plugging in the values, we get: 4 + (91-1) * 2 = 4 + 180 = 184. So, the 91st term in the sequence is 184.

Answer:

Volume = 20

Step-by-step explanation:

To find volume of the shape you split the shape into two shapes: A triangle or pyramid and a rectangle

The volujme of a rectangle is W x L x H

A = 2 x 5 x 8

A = 80

The volume of a pyramid is

A = [tex]\frac{1}{2}[/tex]Bh    The B is the area of the base so B = L x W = 5 x 2 = 10 so B = 10

A = [tex]\frac{1}{2}[/tex] 10 x 4

A = [tex]\frac{1}{2}[/tex] 40

A = 20

A plane flies from Penthaven to Jackson and then back to Penthaven. When there is no wind, the round trip takes 6 hours and 24 minutes, but when there is a wind blowing from Penthaven to Jackson at 50 miles per hour, the trip takes 6 hours and 40 minutes. How many miles is the distance from Penthaven to Jackson?

(Assume that the plane flies at a constant speed, and that the turnaround time is negligible.)

Answers

Answer:800 miles

Step-by-step explanation:

Given

Round trip for Penthaven to Jackson takes 6 hr and 24 minutes in absence of wind

[tex]t_1=6+\frac{24}{60}=6.4\ hr[/tex]

When Wind blows from Penthaven to Jackson it takes 6 hr and 40 min i.e.

[tex]t_2=6+\frac{40}{60}=\frac{20}{3}\ hr[/tex]

Speed of wind [tex]v=50\ mph[/tex]

Suppose x be the distance between Penthaven and Jackson and u be the speed of plane

So initially

[tex]6.4=\frac{x}{u}+\frac{x}{u}[/tex]

[tex]6.4=\frac{2x}{u}[/tex]

[tex]x=3.2u \quad \ldots(i)[/tex]

When wind is blowing then,

[tex]\Rightarrow \frac{20}{3}=\frac{x}{u+v}+\frac{x}{u-v}[/tex]

[tex]\Rightarrow \frac{20}{3}=x[\frac{1}{u+50}+\frac{1}{u-50}][/tex]

[tex]\Rightarrow \frac{20}{3}=x[\frac{2u}{u^2-50^2}]\quad \ldots(ii)[/tex]

Substitute the value of x in [tex](ii)[/tex]

[tex]\Rightarrow \frac{20}{3}=\frac{2u[3.2u]}{u^2-50^2}[/tex]

[tex]\Rightarrow 10[u^2-50^2]=9.6u^2[/tex]

[tex]\Rightarrow 0.4u^2=50^2\times 10[/tex]

[tex]\Rightarrow u^2=\frac{50^2\times 10^2}{4}[/tex]

[tex]\Rightarrow u=250\ mph[/tex]

Thus [tex]x=3.2\times 250=800\ miles[/tex]

A marketing survey involves brand recognition in New York and California. Of 147 New Yorkers surveyed, 79 were familiar with the brand while 78 out of 147 Californians knew this brand as well. Assume that you plan to test the claim that the proportion of New Yorkers who recognize this brand differs from the proportion of Californians who do the same, i.e., p1 ≠ p2. Use the given information to find the pooled sample proportion begin mathsize 14px style p with bar on top end style. Round your answer to three decimal places.

Answers

Answer:

[tex]z=\frac{0.537-0.531}{\sqrt{0.534(1-0.534)(\frac{1}{147}+\frac{1}{147})}}=0.103[/tex]    

Now we can calculate the p value with the following probability taking in count the alternative hypothesis:

[tex]p_v =2*P(Z>0.103) =0.918 [/tex]    

For this case since the p value is large enough we have enough evidence to FAIL to reject the null hypothesis and we can't conclude that we have significant differences between the two proportions analyzed.

Step-by-step explanation:

Information provided

[tex]X_{1}=79[/tex] represent the number of New Yorkers familiar with the brand  

[tex]X_{2}=78[/tex] represent the number of Californians familiar with the brand  

[tex]n_{1}=147[/tex] sample of New Yorkers

[tex]n_{2}=147[/tex] sample of Californians

[tex]p_{1}=\frac{79}{147}=0.537[/tex] represent the proportion New Yorkers familiar with the brand  

[tex]p_{2}=\frac{78}{147}=0.531[/tex] represent the proportion of Californians familiar with the brand  

[tex]\hat p[/tex] represent the pooled estimate of p

z would represent the statistic

[tex]p_v[/tex] represent the value

System of hypothesis

We want to verify if the two proportions of interest for this case are equal, the system of hypothesis would be:    

Null hypothesis:[tex]p_{1} = p_{2}[/tex]    

Alternative hypothesis:[tex]p_{1} \neq p_{2}[/tex]    

The statistic would be given by:    

[tex]z=\frac{p_{1}-p_{2}}{\sqrt{\hat p (1-\hat p)(\frac{1}{n_{1}}+\frac{1}{n_{2}})}}[/tex]   (1)  

Where [tex]\hat p=\frac{X_{1}+X_{2}}{n_{1}+n_{2}}=\frac{79+78}{147+147}=0.534[/tex]  

Repalcing the info given we got:

[tex]z=\frac{0.537-0.531}{\sqrt{0.534(1-0.534)(\frac{1}{147}+\frac{1}{147})}}=0.103[/tex]    

Now we can calculate the p value with the following probability taking in count the alternative hypothesis:

[tex]p_v =2*P(Z>0.103) =0.918 [/tex]    

For this case since the p value is large enough we have enough evidence to FAIL to reject the null hypothesis and we can't conclude that we have significant differences between the two proportions analyzed.

The number of stocks that increase in value is recorded.

Answers

Final answer:

No, the given probability experiment does not represent a binomial experiment because it does not meet the three conditions required for a binomial experiment.

Explanation:

No, the given probability experiment does not represent a binomial experiment. In order for an experiment to be considered a binomial experiment, it must meet three conditions:

1. There must be a fixed number of trials, denoted by 'n'. However, in the given experiment, the number of stocks that the investor purchases is not fixed.

2. There must be only two possible outcomes, called success and failure, for each trial. However, in the given experiment, the outcomes can have three possibilities: the stock can increase, decrease, or have no change in value.

3. The 'n' trials must be independent and repeated using identical conditions. However, in the given experiment, the success or failure of one stock can potentially influence the success or failure of another stock.

(15 pt., 5 pt. each) A player in the Powerball lottery picks five different integers between 1 and 69, inclusive, and a sixth integer between 1 and 26, inclusive, which may duplicate one of the earlier five integers. The player wins the jackpot (currently $43 million) if the first five numbers picked match the first five numbers drawn (in any order) and the sixth number picked matches the sixth number drawn. a. What is the probability that a player wins the jackpot

Answers

Answer:

The probability that a player wins the jackpot is [tex]\frac{1}{292201338}[/tex]

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The order in which the first five numbers are selected is not important, so we use the combinations formula to solve this question.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

First five numbers:

Desired:

5 correct numbers, from a set of 5. So

[tex]D = C_{5,5} = \frac{5!}{5!(5-5)!} = 1[/tex]

Total:

5 numbers from a set of 69. So

[tex]T = C_{69,5} = \frac{69!}{5!(69-5)!} = 11238513[/tex]

Probability:

[tex]P_{5} = \frac{D}{T} = \frac{1}{11238513}[/tex]

-------------

Sixth number:

1 from a set of 26

Then

[tex]P_{6} = \frac{1}{26}[/tex]

-------------

Probability of winning the prize

[tex]P = P_{5} \times P_{6} = \frac{1}{11238513} \times \frac{1}{26} = \frac{1}{292201338}[/tex]

The probability that a player wins the jackpot is [tex]\frac{1}{292201338}[/tex]

Final answer:

To calculate the probability of winning the jackpot in the Powerball lottery, we need to consider the probability of choosing the first five numbers correctly and the probability of choosing the sixth number correctly. Multiply the probabilities from these two steps to find the overall probability.

Explanation:

To calculate the probability of winning the jackpot in the Powerball lottery, we need to consider two parts: the probability of choosing the first five numbers correctly (regardless of order) and the probability of choosing the sixth number correctly.

The probability of choosing the first five numbers correctly is given by:The probability of choosing the sixth number correctly is simply 1 out of 26, since the player can pick any number between 1 and 26, inclusive.

To find the overall probability, we multiply the probabilities from the two steps:

P(winning jackpot) = P(choosing first five numbers correctly) x P(choosing sixth number correctly) = [P(choosing one number correctly)]^5 x P(choosing one number correctly) = (5/69)^5 x 1/26

Calculating this expression gives us the probability of winning the jackpot in the Powerball lottery.

b. Sample sum of squares:
c. Degrees of freedom:
d. The estimated population variance:

Answers

Answer:

Step-by-step explanation:

The mean of the set of data given is

Mean = (60 + 120 + 110 + 80 + 70 + 90 + 100 + 130)/8 = 95

Standard deviation = √(summation(x - mean)/n

n = 8

Summation(x - mean) = (60 - 95)^2 + (120 - 95)^2 + (110 - 95)^2 + (80 - 95)^2 + (70 - 95)^2 + (90 - 95)^2 + (100 - 95)^2 + (130 - 95)^2 = 4200

Standard deviation = √(4200/8) = 22.91

We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean

For the null hypothesis,

µ ≤ 120

For the alternative hypothesis,

µ > 120

This is a right tailed test.

Since the number of samples is small and no population standard deviation is given, the distribution is a student's t.

Since n = 8,

Degrees of freedom, df = n - 1 = 8 - 1 = 7

t = (x - µ)/(s/√n)

Where

x = sample mean = 95

µ = population mean = 120

s = samples standard deviation = 22.91

t = (95 - 120)/(22.91/√8) = - 3.09

We would determine the p value using the t test calculator. It becomes

p = 0.009

Since alpha, 0.05 > than the p value, 0.009, then we would reject the null hypothesis. Therefore, At a 5% level of significance, the sample data showed significant evidence that the average seven-year-old would be able to swim across an Olympic-sized pool in more than 120 seconds after taking lessons from their instructors.

Using the one - sample t test, we can conclude that average 7year old will swim in less than 120 hours

Given the data :

60, 120, 110, 80, 70, 90, 100, and 130. Sample size, n = 8

Using calculator :

Mean = ΣX/n = 760/8 = 95

Standard deviation = 24.49

The degree of freedom :

df = n - 1 df = 8 - 1 = 7

The hypothesis :

[tex]H_{0} : μ > 120 [/tex]

[tex]H_{1} : μ ≤ 120 [/tex]

From the equality sign in the alternative hypothesis, we have a left-tailed test

The solution to the inequality [tex]\( \frac{2}{3}x - \frac{5}{6} \geq \frac{1}{2} \)[/tex] is [tex]\( x \geq 2 \)[/tex].

Given inequality: [tex]\( \frac{2}{3}x - \frac{5}{6} \geq \frac{1}{2} \)[/tex]

Step 1: To simplify the equation, let's find a common denominator for the fractions. The least common multiple (LCM) of 3 and 6 is 6.

Step 2: Rewrite the fractions with the common denominator, which is 6.

So, [tex]\( \frac{2}{3}x - \frac{5}{6} \)[/tex] becomes [tex]\( \frac{4x}{6} - \frac{5}{6} \).[/tex]

Step 3: Now, we have the equation [tex]\( \frac{4x}{6} - \frac{5}{6} \geq \frac{1}{2} \).[/tex]

Step 4: Combine the fractions on the left side of the equation: [tex]\( \frac{4x - 5}{6} \geq \frac{1}{2} \)[/tex].

Step 5: To get rid of the denominator, multiply both sides of the equation by 6 to clear it.

[tex]\( 6 \times \frac{4x - 5}{6} \geq 6 \times \frac{1}{2} \)[/tex]

This simplifies to: [tex]\( 4x - 5 \geq 3 \)[/tex]

Step 6: Now, let's isolate [tex]\(x\)[/tex] by adding 5 to both sides:

[tex]\( 4x - 5 + 5 \geq 3 + 5 \)[/tex]

[tex]\( 4x \geq 8 \)[/tex]

Step-by-step explanation:

Because 9cm2 is 9 times 9 which equals 81 cm.

Final answer:

To find the length of one side of a cube with a surface area of 9 cm², set up the equation s² * 6 = 9. Simplify and solve for s to find that the length of one side is √(9/6) cm.

Explanation:

The question is asking about the surface area of a cube. The surface area of a cube can be found by multiplying the length of one side by itself, and then multiplying that result by 6 since a cube has 6 faces. So, if the surface area of a cube is 9 cm², you can set up the equation: 9 = s² * 6. Simplifying, you get s² = 9/6. Taking the square root of both sides, you find that s = √(9/6). Therefore, the length of one side of the cube is √(9/6) cm.

87.49 %

89.44 %

90.32 %

91.15%

Answers

Answer:

89.44%

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question:

[tex]\mu = 45, \sigma = 5.6[/tex]

If you score 52 on the test, what percentage of test takers scored lower than you?

This is the pvalue of Z when X = 52.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{52 - 45}{5.6}[/tex]

[tex]Z = 1.25[/tex]

[tex]Z = 1.25[/tex] has a pvalue of 0.8944.

So 89.44% of test takers scored lower than you.

Beth's number, which indicates 60 parts out of 100, can be expressed as 60%, 0.60, 60/100, or in simplest form, 3/5. These representations are commonly used in mathematics to show percentages and their equivalent values.

Beth writes a number that shows 60 parts out of 100. In mathematics, expressing a part out of 100 is essentially describing a percentage. So, Beth's number could be expressed in several ways that all represent 60 out of 100. The simplest form would be 60%, which directly translates to 60 per 100. Another possible representation could be 0.60, which is the decimal form equivalent to 60%. If we were to convert this percentage into a fraction, it would be
60/100, which can also be simplified to
3/5. It cannot be a number such as N(60, 5.477) which suggests a normal distribution with a mean of 60 and a standard deviation of 5.477, nor can it be .9990 which is not equivalent to 60 parts out of 100 in any common mathematical representation.

On a coordinate plane, two parabolas open up. The solid-line parabola, labeled f of x, goes through (negative 2, 4), has a vertex at (0, 0), and goes through (2, 4). The dashed-line parabola, labeled g of x, goes through (negative 6, 10), has a vertex at (negative 4, 6), and goes through (negative 2, 10).

What is the equation of the translated function, g(x), if

f(x) = x2?


g(x) = (x – 4)2 + 6

g(x) = (x + 6)2 – 4

g(x) = (x – 6)2 – 4

g(x) = (x + 4)2 + 6

Answers

Answer:

[tex]y = (x+4)^{2}+6[/tex]

Step-by-step explanation:

The parabola with vertex at point (h,k) is described by the following model:

[tex]y - k = C\cdot (x-h)^{2}[/tex]

The equation which satisfies the conditions described above:

[tex]y - 6 = (x+4)^{2}[/tex]

[tex]y = (x+4)^{2}+6[/tex]

The two points are evaluated herein:

x = -6

[tex]y =(-6+4)^{2}+6[/tex]

[tex]y = (-2)^{2}+6[/tex]

[tex]y = 4 + 6[/tex]

[tex]y = 10[/tex]

x = -2

[tex]y = (-2+4)^{2}+6[/tex]

[tex]y = 2^{2} + 6[/tex]

[tex]y = 4 + 6[/tex]

[tex]y = 10[/tex]

The equation of the translated function is [tex]y = (x+4)^{2}+6[/tex].

We have been given a right triangle. We are asked to find the value of x.

We can see that x is opposite side to angle that measures 62 degrees and adjacent side to angle is 4 units.

We know that tangent relates adjacent and opposite side of right triangle.

[tex]\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}[/tex]

[tex]\text{tan}(62^{\circ})=\frac{x}{4}[/tex]

[tex]4\cdot \text{tan}(62^{\circ})=\frac{x}{4}\cdot 4[/tex]

[tex]4\cdot (1.880726465346)=x[/tex]

[tex]7.522905861384=x[/tex]

[tex]x=7.522905861384[/tex]

[tex]x\approx 7.52[/tex]

Therefore, the value of x is approximately 7.52 units and option 'd' is the correct choice.

7. There are seven clarinet players in the concert band. In how
many ways can they be seated in seven chairs at a concert?
Use the Fundamental Counting Principle.
A. 5,040
C. 840
B. 2,520
D. 210​

Answers

Answer:

Step-by-step explanation:

The number of people in the cabinet is 7.

n = 7.

Fundamental Counting Principle states that if there are m ways of doing a thing and there are n ways of doing other thing then there are total m*n ways of doing both things.

now using fundamental Counting Principle.

since 7 players can sit on chair in

7 , 6, 5 , 4, 3 , 2, 1 ways then together they can be seated in

7 * 6 * 5 * 4 * 3 * 2 * 1 ways = 5,040 ways.

To arrange this seven people in a straight cabinet, the number of way to arrange them is n!

Then,

n! = 7! = 7 × 6 × 5 × 4 × 3 × 2 × 1 = 5040.

There are 5040 ways of arranging them.

Option A is correct.
