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.

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
