Assume x is a normal random variable with mean 20 and variance 16, and y is a gamma random variable with parameters 5 and 2. in addition x and y are independent. construct a box with length l = |x|, width w = 2|x|, and height h = y . let v be the volume of the box. calculate the expected value e[v ]?

Without any equipment, you can see stars that are 2{,}800{,}0002,800,0002, comma, 800, comma, 000 light-years away. by looking through a small telescope, you can see stars that are 3{,}112{,}000{,}0003,112,000,0003, comma, 112, comma, 000, comma, 000 light-years away. approximately how many times as far can you see using a small telescope as without any equipment?
