If a and b are constants, then show that `var (ax+b)=a^2 var (x)`.

X is a random variable and 'a' and 'b' are constant show that var(aX+b) = a^2 var(X) .

if a and b are any two constants, then prove that Var (aX+b)=a^2Var(X) .

Prove that Var (a+bx)= b^(2) Var(x)

If x is a random variable and a,b are constants, then Var (ax + b) = _______.

If a is a constant prove that (i) var(a)=0 (ii) var (aX)=a^(2)var(X) (iii) Var(ax+b)=a^(2)var(X)

answer any one question : (ii) if X and Y are two independent variables , then rove that var(aX+bY ) =a^2 var (X) +b^2 var (Y) , where a and b are constants

If k is a constant, then Var(k) is equal to -

If X and Y are two independent variables, then prove that var(aX+bY)=a^2var(X)+b^2var(Y) , where a and b are constants.

If X is a random vairalbe, then for any constant a (neo) and b, var (ax+b) =

Var(5x-2)=?if Var(X)=1
