leonid [27]

Answer: The finial answer is 15.8

This problem is just one about triangles! All of the faces of the cube are perpendicular to their adjacent faces, so the diagonal of one of the face will be a right angle with the edge of the cube.

A scientist is interested in the effect of time spent with parents and number of hours
gladu [14]

Answer: If X = 5, z=<u>-3</u>

If X = 37, z= <u>3.4</u>

Step-by-step explanation:

We know that the formula to find the z-score for any random variable x is given by :-

z=\dfrac{x-\mu}{\sigma}

, where \mu = Population mean

\sigma = Population standard deviation.

As per given , we have

\mu=20\\\\\sigma=5

Then , the z-score for x =5

z=\dfrac{5-20}{5}=\dfrac{-15}{5}=-3

i.e. If X = 5, z=<u>-3</u>

When x =37,then z=\dfrac{37-20}{5}=\dfrac{17}{5}=3.4

i.e. If X = 37, z= <u>3.4</u>
