Let X represent the number of customers arriving during the morning hours and let Y represent the number of customers arriving during the afternoon hours at a diner. You are given: a. X and Y are Poisson distributed.
b. The first moment of X is less than the first moment of Y by 8.
c. The second moment of X is 60% of the second moment of Y.

Required:
Calculate the variance of Y.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
