Find Perimeter of Right Triangle using PowersExample for #8 on Quiz 10.1 to 10.4. I made a few minor errors, but nothing major enough to re-record for. At one point I wrote "d2" when I meant "d6" and one of my warm up examples has an extra "+" sign in it, for no good reason. I also must love the word "so." SOOO ... sorry!

Correlation Coefficient
Additional Resources
In statistics, the correlation coefficient r measures the strength and direction of a linear relationship between two variables on a scatterplot. The value of r is always between +1 and –1. To interpret its value, see which of the following values your correlation r is closest to: Exactly –1.
