The hypotenuse of a right triangle is 5 inches long. The shorter leg is 1 inch shorter than the longer leg. Find the side lengths of the triangle.

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

answer: no, but if it does it's a obvious pattern.

step-by-step explanation:

translate k to n and reflect across the line containing jk.
