For a population with mean (μ) = 100 and standard deviation (σ) = 20, the X value corresponding to z = 1.50 is 130.
<h3>What is a z-score?</h3>
A z-score is also referred to as a standard score and it's a measure of the distance between a raw score and the mean, when standard deviation units are used.
<h3>How to determine the value of x?</h3>
In Statistics, the standardized z-score is giving by this formula:
Making x the subject of formula, we have:
x = Zσ + μ
Substituting the given parameters into the formula, we have;
x = 1.50(20) + 100
x = 30 + 100
x = 130.

Answer:
more than 20 dollars
Step-by-step explanation:
It doesn't matter how much money was in the account before; it matters that the account was overdrawn, which means whatever amount of money was taken out made the balance go negative. Then, the problem says that after the deposit was made, the account had a balance of 20 dollars, which means the person must have put in at least 20 dollars to make the account go from negative to zero, and then to 20.

Answer:
6
Step-by-step explanation:
216 raised to the one third power is the same as asking for the cubed root of 216. 6x6x6=216
