In 2016, the mean score on the AP Art History exam was 3.8, with a standard deviation of 1.2. The mean score on the AP English e

Ulleksa [173]

Answer:

$X+Y \sim N(\mu_X +\mu_Y , \sqrt{\sigma^2_X +\sigma^2_Y})$

The mean is given by:

$\mu = 3.8+2.9= 6.7$

And the standard deviation would be:

$\sigma =\sqrt{1.2^2 + 1.7^2} = 2.08$

And the distribution for X+Y would be:

$X+Y \sim N(6.7 , 2.08)$

And the best answer would be:

D.) Mean, 6.7; standard deviation, 2.08

Step-by-step explanation:

Let X the random variable who represent the AP Art History exam we know that the distribution for X is given by:

$X \sim N(3.8, 1.2)$

Let Y the random variable who represent the AP English exam we know that the distribution for X is given by:

$X \sim N(2.9, 1.7)$

We want to find the distribution for X+Y. Assuming independence between the two distributions we have:

$X+Y \sim N(\mu_X +\mu_Y , \sqrt{\sigma^2_X +\sigma^2_Y})$

The mean is given by:

$\mu = 3.8+2.9= 6.7$

And the standard deviation would be:

$\sigma =\sqrt{1.2^2 + 1.7^2} = 2.08$

And the distribution for X+Y would be:

$X+Y \sim N(6.7 , 2.08)$

And the best answer would be:

D.) Mean, 6.7; standard deviation, 2.08

For every 3 dogs Carol has, she keeps 12 treats. Which is the correct rate?

Tems11 [23]

Answer:

4 treats per dog.

Step-by-step explanation:

Find the rate that she keeps for one dog. As it gives you the rate for 3 dogs, simply divide 3:

(3 dogs/12 treats)/(3/3) = (1 dog/4 treats).

Carol keeps 4 treats for every dog she has.

Alyssa started hiking at an elevation of 1500ft. After 2 hours, she was at 1200ft. Which integer desceibes her change in elevati

SpyIntel [72]

Answer:

-300.

Step-by-step explanation:

First, you'd have to subtract 1500 from 1200. This gives you 300, but since she is descending rather than ascending, the number is negative rather than positive.

What form is this equation in? y + 6 = (1/2)(x - 4)

maks197457 [2]

Y +6 =(1/2)(x+4)

y +6 = 1/2 x +2
y=1/2 x - 4

or 1/2 x -y = 4
