Answer:
a) E(y) = 0.8
b) The average subcharge is $165
Step-by-step explanation:
We are given the following distribution in the question:
y: 0 1 2 3
P(y): 0.50 0.25 0.20 0.05
a) E(y)
b) Expected value of subcharge
Subcharge =
Expected value of subcharge =
Thus, the average subcharge is $165
Answer:
add them all up together and then divide by the number of items
Step-by-step explanation:
The answer is -3
-12c = 43 - 7
-12c = 36
÷ -12 ÷-12
c = -3
