Answer:
Step-by-step explanation:
Linear pair, so sum of both angles is 180
x - 2 + 2 +4x = 180
Add the like terms
5x +0 = 180
5x = 180
Divide both sides by 5
x = 180/5
x = 36
Answer: The expected value would be -$9.022.
Step-by-step explanation:
Since we have given that
Number of throws made by basketball player = 217
Number of free throws = 357
So,
Let X be the amount he lose or win.
X can be $32 or -$21
So, it becomes,
and
So, the expected value would be
Hence, the expected value would be -$9.022.
Answer:
