Which of the following statement is not true? A. The expected value of a discrete random variable X with a set of possible values D and probability mass function p(x) is ; B. If the expected value of a discrete random variable X is $125, then the expected value of the linear function h(X) = 100 X + 25 (3-X) is $15,550 C. For any constant c and discrete random variable X, D. For any constant c and discrete random variable X, E(X+c) = E(X)+c

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
