Problem 2: During a field trip, Anne accidently finds a meteorite weigh 10g. She took it back to a chemical lab to analyze the component, and find that there are two elements inside, which have decay constant λx and λy respectively. She knew from class that the half life function for both materials satisfy N(t, λx, y) = 10e-(2x+y), 0≤1x, dy ≤ 10 : λx, Anne knows that N(...) is the joint density function for both constants when t = 2 seconds. What is the standard deviation of variable Z = e^x-^y
