In the latter case a sample of data from such a distribution can be used to. A mnemonic for the above expression is "mean of square minus square of mean". .. The variance of a finite sum of uncorrelated random variables is equal to the .. for all random variables X, then it is necessarily of the form varphi(x) = a x^2 + b.

So that's equal to z squared.. are kind of my restatement of the Pythagorean Theorem. x squared plus y squared is equal to z squared. And that's this one right there, choice B. Next problem.. So C over here will be 2 to the right of the y-axis.
