Jessica went shopping and bought a pair of jeans that were on sale for 25% off the original price of $23.98. A 6% tax was also a
Ghella [55]

Answer:

$19.07

Step-by-step explanation:

First off we need to find the discounted price of the jeans that Jessica bought.

We find the discount by multiplying the original price by 25% or 0.25

Discount Price = 23.98 x 0.25

Discount Price = 5.99

Now we subtract the discount from the original price.

Discounted Price = 23.98 -5.99

Discounted Price = 17.99

Now that we have the discounted price, we then compute for the sales tax.

Sales Tax = 17.99 x 0.06

Sales Tax = 1.08

Then we add the sales tax to the discounted price.

Total Price = 17.99 + 1.08

Total Price = $19.07

Jessica spent $19.07 on the jeans.

A circular garden has a diameter of 6 feet. Which of the following is closest to the area of the garden?
oksian1 [2.3K]
The answer to this problem is 'B'.

This is because to find the area of a circle your formula is
A = 3.14•r²
So your first step is

1. Find the radius by dividing the diameter (6) by 2
6/2 = 3 Radius= 3

Now that you have found the radius (3) plug the number in the formula
2. A = 3.14•3²
OR
A = 3.14•3•3

Finally, solve the last step - Find the area
3.14 • 3 • 3 = 28.26
A = 28.26

Jane runs 6 miles in 44 minutes. At the same rate, how many minutes would she take to run 9 miles?
polet [3.4K]

Answer:

66 minutes

Step-by-step explanation:

<u>Solve for speed</u>

speed = distance / time

speed = 6 / 44

<u>Substitute in speed to second equation and solve for time</u>

distance / speed = time

9 / (6/44) = time

66 = time taken

BaLLatris [955]

Answer:

The test statistic is z = 1.25

Step-by-step explanation:

We are interested in determining whether or not the proportion of the student who experience anxiety during the exam is significantly more than 80%.

At the null hypothesis, we test if the proportion is 80%, that is:

H_0: p = 0.8

At the alternate hypothesis, we test if the proportion is more than 80%, that is:

H_a: p > 0.8

The test statistic is:

z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

In which X is the sample mean, \mu is the value tested at the null hypothesis, \sigma is the standard deviation and n is the size of the sample.

80% is tested at the null hypothesis:

This means that \mu = 0.8, \sigma = \sqrt{0.2*0.8} = 0.4

A random sample of 100 students was taken. Eighty-five of the student in the sample experienced anxiety during the exam.

This means that n = 100, X = \frac{85}{100} = 0.85

The test statistic is

z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

z = \frac{0.85 - 0.8}{\frac{0.4}{\sqrt{10}}}

z = 1.25

The test statistic is z = 1.25
