Let \mu be the mean and \sigma the standard deviation.

Joe's score tells you that \dfrac{288-\mu}\sigma=-2, while Jon's score says \dfrac{633-\mu}\sigma=1. Solve this to get \mu=518 and \sigma=115.

Why is the percent not the same as the percent you find from he percent of money
nexus9112 [7]
Percentage is a way to express a relation between two numbers as a fraction of 100<span>. In other words, the percentage tells us how one number relates to another. If we know that number A is </span>25%<span> of number </span>B<span>, we know that </span>A<span> to </span>B<span> is like </span>25<span> is to </span>100<span> (one more transformation: </span>A<span> is four times smaller than </span>B<span>). This is Percentage Calculator's lesson on what is percentage. 
  But in money a percent is how many cents past the dollar the number is.</span>
