High school students from track teams in the state participated in a training program to improve running times. Before the train

Answer:

b. The values X and Y are independent therefore, the mean is 34 seconds and the standard deviation is 50 seconds

Step-by-step explanation:

Subtraction between normal variables:

When two normal variables are subtracted, the mean is the difference of the means, while the standard deviation is the square root of the sum of the variances.

Before the training, the mean running time for the students to run a mile was 402 seconds with standard deviation 40 seconds.

This means that $\mu_X = 402, \sigma_X = 40$

After completing the program, the mean running time for the students to run a mile was 368 seconds with standard deviation 30 seconds.

This means that $\mu_Y = 368, \sigma_Y = 30$

Which of the following is true about the distribution of X-Y?

They are independent, so:

$\mu = \mu_X - \mu_Y = 402 - 368 = 34$

$\sigma = \sqrt{\sigma_X^2+\sigma_Y^2} = \sqrt{40^2+30^2} = 50$

This means that the correct answer is given by option b.

Which function will have the steepest graph? y = –2x y =-1/2 x y = 3/2x y =5/2 x

timofeeve [1]

The steepest graph is gonna have the largest slope....but u have to use the absolute value of the slopes to compare

y = -2x.....slope is -2....| -2 | = 2
y = -1/2x...slope is -1/2....| -1/2 | = 1/2
y = 3/2x....slope is 3/2 (or 1 1/2)...| 1 1/2} = 1 1/2
y = 5/2x...slope is 5/2 (or 2 1/2)...| 2 1/2| = 2 1/2

so the steepest graph is : y = 5/2x
