Just by the language difference means subtract,
Y^2-25 is the difference of squares
factored it's the sum and difference of their square roots
(x+5) (x-5)
<span>Answer: Skewed to right with mean 0 and S.D. 1
Explanation: Let's assume the z-scores as a linear transformation.
then z=(x-mean)/S.D. = (x-30)/15
z(mean) = (30-30)/15= 0
z(sigma) = 15/15 = 1
