Answer: $272

Step-by-step explanation:

Her amount due = 37,000(1.004)^273

If her monthly payment is x

She'll pay = x(1.004)^240 + x(1.004)^239 + ....x(1.004)^1 + x

= x[(1.004)^241 - 1]/(1.004-1) =

Her payment = Amount due

x[(1.004)^241 - 1]/(1.004-1) = 37000(1.004)^273

404x = 37000(1.004)^273 = 110029

x = 110029/404 = $272

Monthly payment = $272

If this figure is a regular figure? How many degrees does each angle measure?

bearhunter [10]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$\frac{(5 - 2) \times 180}{5} = \\$

$\frac{3 \times 18 \times 10}{5} = 3 \times 18 \times 2 = \\$

$54 \times 2 = 108$

Thus each angle has a measure of 108° degrees.

-104=-8(k+8) K = ? Solution please if can?

maksim [4K]

Let's solve this question by step by step.

Layout equation.

−104=−8(k+8)

Step 1: Simplify both sides of the equation.

−104=−8(k+8)

−104=(−8)(k)+(−8)(8)(Distribute)

−104=−8k+−64

−104=−8k−64

Step 2: Flip the equation.

−8k−64=−104

Step 3: Add 64 to both sides.

−8k−64+64=−104+64

−8k=−40

Step 4: Divide both sides by -8.

-8k/-8=-40/-8

The answer for this problem is k=5.

Hayden wanted to investigate whether there was a difference in the time spent in the checkout line between two grocery stores. S

Ber [7]

Answer:

No. The data in this study were not based on a random method. This is a key requirement for an inference to be made from the two-sample t-test.

Step-by-step explanation:

1. Hayden can use the two-sample t-test (also known as the independent samples t-test)to find out if there was a difference in the time spent in the checkout time between two grocery stores and to conclude whether the difference in the average checkout time between the two stores is really significant or if the difference is due to a random chance. There are three conditions to be met when using the two-sample t-test.

2. The first condition is that the sampling method must be random. This requirement was not met in this study. Each customer from each store should have an equal chance of being selected for the study. This was not achieved.

3. The distributions of the sample data are approximately normal. This is achieved with a large sample size of 30 customers selected for each study.

4. The last but not the least condition is the independence of the sample data. Sample data here is independent for both samples.

The X multiple answers are 60 or 55 or 9 or 27 and

Molodets [167]

Step-by-step explanation:

It is an isosceles triangle , it has two equal angles both 55°.

All Isosceles triangles have two equal angles and two equal sides.

So in this case x +18 is equal to 3x, and to find x you will equal them to each other to create a linear equation and solve.

x + 18 = 3x

x - 3x = -18

-2x = -18

× = -18 / -2

× = 9 (ans)

Hope I was able to help. Good Luck :)))
