The joint distribution for the length of life of two different types of components operating in a system is given by f(y1, y2) = 1 8 y1e−(y1 + y2)/2, y1 > 0, y2 > 0, 0, elsewhere. The relative efficiency of the two types of components is measured by U = Y2 Y1 . Find the probability density function for U. fU(u) = , u ≥ 0 0 , u < 0

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).
