Q1) Use the derivative if the function y = square root of x to obtain an appropriate value for square root of 16.02
Q2)X and Y are independent random variables. Let V1 and V2 denote the variance of X and Y, respectively. Let the random variable Z be defined to be [aX+bY] , where a and b are two positive real numbers. It is known that V1>1 , variance of Z is 1, and covariance between Y and Z is 1. In terms of V1 and V2, what are a and b?
sir, my ans comes out as : b=1/V2, a square = V2 - 1/ V1. V2.
pls check it.
