The following table shows the probability distribution for a discrete random
variable.
x | 22 | 24 | 25 | 30 | 33 | 37
P(X) 0.16 0.09 0.18 0.12 0.24 0.21
What is the mean of this discrete random variable? That is, what is E(X), the
expected value of X?
O A. 30.27
O B. 27.5
O C. 29.47
O D. 28,5

Explanation:

The expected value, E(X) or mean of a discrete random variable is given by:

Using the data from the table:

Computing:

29.47, or option C.

Step-by-step explanation:

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

where are the images of the functions i can only see the question you typed.
