(a) Suppose that X, and X2 are independent rv's with means 5 and 10 kips, respectively, and standard deviations 1.3 and 2.6 kip, respectively. If a = 7 ft and a, = 14 ft, what is the expected bending moment and vwhat is the standard deviation of the bending moment? (Round your standan deviation to three decimal places.) expected bending moment kip-ft standard deviation kip-ft
