Answer:

0.1 repeating, or 1/9

Step-by-step explanation:

To solve, you have to first leave the 3, then add up the exponents,

4 - 6 = -2.

Then -2 becomes the exponent, so 3^-2.

When simplified to a number, it is

0.1 repeating, or 1/9.

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>
