Help please!!!

Exercise 1. Let K be a. random variable with mean 60 and standard deviation 4. Let L be a. random vari able with mean 100 and standard deviation 5. Suppose E (K L) = 6007. (A) Find ConUf, L). (13) Find CHINE, L). (C) Find the mean and variance of W\" 2 3K L + 20. Exercise 2. Below is a list of assertions about two random variables labeled X and Y. Let #X and 0X be the mean and standard deviation for X and let ny and my be the mean and standard deviation for Y. Deter mine which statements must be true and which must be false. Ver(2X 3Y + 5) = 20% 35% + 5
