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

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

If a and b are constants, then show that 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 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)

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.

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

The probability distribution of a discrete random variable x is given by The value 6E(X^(2))-Var(x) is

The value of Var (x) is

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