Answer:

**Answer: X=5/4 Y=5**

**Step-by-step explanation: **

The time needed for all college students to complete a certain paper-and-pencil maze follows a normal distribution with a population mean of 30 seconds and a population standard deviation of 3 seconds. You wish to see if the mean time μ (where μ stands for population mean) is changed by vigorous exercise, so you have a group of nine college students exercise vigorously for 30 minutes and then complete the maze. It takes them an sample average of 31.2 seconds to complete the maze. Use this information to test the hypotheses: H0: μ = 30, Ha: ≠30 at the significance level of 0.01. You conclude:a) There is not enough evidence to support the claim.b) There is enough evidence to support the claim.

What percentage is the shaded area

The drawing below shows circle B and circle E. The MAC = m DF, and the length of AC is 3 times the length of DF.

Mr Thompson wants to cut a 5-ft rope into a 1/4-ft sections how many 1/4 sections will he have

Help me, please !! For a reason, Tony took 1/3 his money for book and then he took 1/5 again for beer. And now tony have 28$, how many money he had before? Please anwer with the pattern, thank you

Divide 1,250 by 41. This comes out to about 30.5; however, he can’t buy only half a box so the answer is 30 boxes.

**Answer:**

first option

imagine the line y = x as a mirror

**Answer:**

The answer is **A**. "the function h because the graphs of ƒ and h are symmetrical about the line y = x"

2.) 1/5×5×5×5

3.) 5×5×5×5

4.) 3

The **value **of the **expression** 5⁶ / 5² will be 5 x 5 x 5 x 5. Then the **correct** option is **C**.

When the **relevant** factors and natural** laws **of a **mathematical** model are given** values**, the outcome of the **calculation** it describes is the expression's **outcome**.

Making anything **easier** to accomplish or **comprehend**, as well as making it **less difficult**, is the definition of **simplification**.

The **expression** is given below.

⇒ 5⁶ / 5²

**Simplify **the expression, then the **value **of the expression will be

⇒ 5⁴

⇒ 5 x 5 x 5 x 5

The **value **of the **expression** 5⁶ / 5² will be 5 x 5 x 5 x 5. Then the **correct** option is **C**.

**Answer:**

3

**Step-by-step explanation:**

When dividing exponents you subtract the top exponent from the bottom exponent so you would have 6-2 which is 4. Answer 3 is the only one that has 4 5's in the numerator.

b. the chance of obtaining a difference in GPAs between male and female scholarship athletes as large as that observed in the sample if there is no difference in mean GPAs is 0.287.

c. the GPAs for male and female scholarship athletes are identical, except for 28.7% of the athletes.

d. the chance that a pair of randomly chosen male and female scholarship athletes would have a significant difference in GPAs is 0.287.

**Answer:**

A university administrator obtains a sample of the academic records of past and present scholarship athletes at the university. The administrator reports that no significant difference was found in the mean GPA (grade point average) for male and female scholarship athletes ( P = 0.287 ). This means that - the GPAs for male and female scholarship athletes are identical, except for 28.7% of the athletes. (Option C)

**Step-by-step explanation:**

The probability of obtaining results as extreme as the observed results of a statistical hypothesis test, assuming that the null hypothesis is correct is known as p-value.

The p-value is used as an option to reject points to provide the smallest level of significance at which the null hypothesis would be rejected. A smaller p-value means that there is stronger evidence in favor of the alternative hypothesis.

Only the statement expressed by option C is in correlation with the meaning of p-value.

compounded quarterly. After 9 years, how much more money would Zachary have in

his account than Peyton, to the nearest dollar?

After 9 **years**, Zachary has $615.2 **more **than Peyton in his account.

A loan or deposit's interest is **computed **using the starting principle and the interest **payments **from the ago decade as compound interest.

We know that the **compound **interest is given as

A = P(1 + r)ⁿ

Where A is the amount, P is the **initial **amount, r is the rate of interest, and n is the **number **of years.

The **equation **is given as,

Zachary **invested **$5,300 in an account paying an **interest **rate of 9 % compounded **continuously**. Then the amount is calculated as,

P = $5,300 × 2.2479

P = $11,913.9

Peyton **invested **$5,300 in an account paying an **interest rate **of 85% compounded quarterly. Then the **amount **is calculated as,

A = $5,300 × 2.1318

A = $11,298.7

The **difference **is given as,

D = $11,913.9 - $11,298.7

D = $615.2

After 9 **years**, Zachary has $615.2 **more **than Peyton in his account.
