Answer:
This is the answer: choose
A
D
E
Answer: Choice C) y = 30/x
Inverse variation equations are of the form y = k/x. In this case, k = 30. We can rearrange the format to get x*y = k after multiplying both sides by x. So y = 30/x can be turned into x*y = 30.
Answer:
The solution to the inequality is:

The number line solution graph is also attached below.
Step-by-step explanation:
Given the inequality

Add 8 to both sides


Divide both sides by 2


Add 3 to both sides


Thus, the solution to the inequality is:

To find 2/3 of an hour first we will divide 1 hour that is 60 mins into 3parts so we will get 20 mins.
Using the normal distribution, we got that expression for the z-score of her test score is

<h3>What is Normal
Probability Distribution?</h3>
it's a type of probability distribution which is symmetric about the mean, it gives data near the mean are more frequent than data far from the mean.
Given that mean =
and standard deviation =
X=73
we know that formula of z-score is

Hence Z-score can be calculated as

Using the normal distribution, we got that expression for the z-score of her test score is
