The expected value of a random variable X is 35. The variable is transformed by multiplying X by 4 and then adding 1 to it. Find the expected value (mean)
of the transformed variable. A. 135 B.117 C. 154 D.141

Expected value x= 35

linear transformation is defined as a + bx

here, b=4, a=1

The transformation is

now, expected value,

substitute the value of a=1, b=4 and l=35

So, the expected value of the transformed variable is 141.
