The answer to question one is $5.39. I got this answer by adding 16.49 and 1.62 to see how much she had to pay for the jeans and the tax which is 18.11. Then I subtracted 28.69 by 18.11 so I could find out how much money was for both of the jeans which is 10.78. Last I divided by 2 because there are 2 jeans which the answer is 5.39.

The answer to question two is $4.75. I got this answer by adding the coupon and the money for the snack so I could find out how much money was the admission for both of them which is 9.50. Then I divided it by 2 because there were 2 people. And last I got the answer $4.75!!!!

Hope this helps u!!!!

Factor of this expression 3X + 21 IS

Answers

The answer is: 3 (x + 7)

Explanation:

3 can go into 3x one time.
3 can go into 21 seven times.

Therefore when factorized it is written as:

3 (x + 7)

Answer:

3 (x + 7)

Step-by-step explanation:

3 can go into 3x one time.

3 can go into 21 seven times.

Therefore when factorized it is written as:

3 (x + 7)

The nicotine content in cigarettes of a certain brand is normally distributed with mean (in milligrams) μ and standard deviation σ=0.1. The brand advertises that the mean nicotine content of their cigarettes is 1.5, but you believe that the mean nicotine content is actually higher than advertised. To explore this, you test the hypotheses H0:μ=1.5, Ha:μ>1.5 and you obtain a P-value of 0.052. Which of the following is true? A. At the α=0.05 significance level, you have proven that H0 is true. B. This should be viewed as a pilot study and the data suggests that further investigation of the hypotheses will not be fruitful at the α=0.05 significance level. C. There is some evidence against H0, and a study using a larger sample size may be worthwhile. D. You have failed to obtain any evidence for Ha.

Answers

Answer:

Step-by-step explanation:

This is a test of a single population mean since we are dealing with mean.

From the information given,

Null hypothesis is expressed as

H0:μ=1.5

The alternative hypothesis is expressed as

Ha:μ>1.5

This is a right tailed test

The decision rule is to reject the null hypothesis if the significance level is greater than the p value and accept the null hypothesis if the significance level is less than the p value.

p value = 0.052

Significance level, α = 0.05

Since α = 0.05 < p = 0.052, the true statement would be

At the α=0.05 significance level, you have proven that H0 is true. B.

A television set is 36 inches wide and has a diagonal length of 42 inches. To the nearest inch, how tall is the set?

Answers

The height of the television set would be 21.6 inches to the nearest inch.

What is Pythagoras' Theorem?

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

$|AC|^2 = |AB|^2 + |BC|^2$

where |AB| = length of line segment AB. (AB and BC are the rest of the two sides of that triangle ABC, AC being the hypotenuse).

We have been given that the television set is 36 inches wide and has a diagonal length of 42 inches.

Let b represent the height of the television set.

We will use the Pythagorean theorem;

36² + b² = 42²

1296 + b² = 1764

-1296. -1296

b² = 468

√ b² =√ 468

b = height

b = 21.6 inches

Therefore, the height of the television set would be 21.6 inches to the nearest inch.

Pythagorean theorem.
36² + b² = 42²
1296 + b² = 1764
-1296. -1296
b² = 468
[square root] b² = [square root] 468
b= height =21.6 inches

Suppose a professor splits their class into two groups: students whose last names begin with A-K and students whose last names begin with L-Z. If p1 and p2 represent the proportion of students who have an iPhone by last name, would you be surprised if p1 did not exactly equal p2? If we conclude that the first initial of a student's last name is NOT related to whether the person owns an iPhone, what assumption are we making about the relationship between these two variables?

Answers

a) Even if the distribution of iPhones by last name is completely uniform in the population generally, there is no reason to believe that the proportions in the sample represented by the class will be identical.
I would not be surprised to see p1 ≠ p2.

b) Saying the variables are not related is the same as saying the variables are independent.

Evaluate k - m if k = 8, m = -7, and p = -10.
