We can take the two points given and plug them into the slope formula.

$\sf~m=\dfrac{y_2-y_1}{x_2-x_1}$

(-3, 3), (1, -5)
x1 y1 x2 y2

$\sf~m=\dfrac{-5-3}{1-(-3)}$

Subtract:

$\sf~m=\dfrac{-8}{4}$

Divide:

$\sf~m=-2$

The cost of a sweatshirt is 175% the cost of a T-shirt. A T-shirt costs $13.

Molodets [167]

Answer:

$68.25

Step-by-step explanation:

1. First, to find the cost of one sweatshirt, we multiply 175 by 13, and then divide by 100.

$175 * 13 = 2275$
$2275/100=22.75$

2. Now, we know that one sweatshirt costs $22.75. To find the cost of three sweatshirts, we multiply 22.75 by 3.

$22.75 * 3$
$68.25$

Therefore, the cost of 3 sweatshirts is $68.25.

foot locker uses sales per square foot as a measure of store productivity last year the mean annual sales per square foot was 39

lord [1]

Answer:

There is a 82% probability that th esample mean annual sales per square foot is at least $384.

Step-by-step explanation:

We have a population with mean 390 and standard deviation 45.83.

Samples of size n=49 are taken.

The parameters of the sampling distribution are:

$\mu_s=\mu=390\\\\ \sigma_s=\dfrac{\sigma}{\sqrt{n}}=\dfrac{45.83}{\sqrt{49}}=\dfrac{45.83}{7}=6.547$

First, we have to calculate the z-score that satisfies:

$P(z>z^*)=0.82$

This z-score, looked up in a standard normal distribution table, is z=-0.915.

Then, we can calculate the sample mean as:

$M=\mu_s+z\cdot\sigma_s=390+(-0.915)\cdot 6.547=390-6=384$

There is a 82% probability that th esample mean annual sales per square foot is at least $384.

Which of these is a correct expansion of (4x - 2)(2x + 3)?

RideAnS [48]

Answer:

It's 8x²+8x-6

Step-by-step explanation:

If you multiply each component you get:

4x * 2x = 8x²

4x * 3 = 12x

-2 * 2x = -4x

-2 * 3 = -6

Adding everything you have the result.
