The probability is 0.8997.

We will use a z-score to answer this question.  z-scores are given by the formula
z=\frac{X-\mu}{\sigma}

With our information, we have
z=\frac{622-590}{25}=\frac{32}{25}=1.28

Looking this up in a z-table (http://www.z-table.com) we see that the area to the left of this (everything less than, up to this value) is 0.8997.

I WILL GIVE BRIANLIEST WHOEVER ANSWER!!<br> 17. Find (f/g)(X) for the following functions.
Genrish500 [490]

Answer:

Option 3

Step-by-step explanation:

(f/g)(x) = f(x)/g(x)

Since g(x) is in the denominator, it can't be 0.

(Functions is undefined when the denominator = 0)

This fraction becomes undefined when:

-14x² - 1 = 0

14x² = -1

x² = -1/14

So x² should not be -1/14
