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:
0.00627 :)
Step-by-step explanation:
Answer:

Step-by-step explanation:
Ir order to find the value of n in the given linear equation:
you have to perform the properties of equalities to obtain an equivalent equation.
You have to perform these properties in each side of the equation.
Applying the subtraction property (which is the subtraction of the same number to each side of the equation):
Adding
to each side:

This way you can obtain the value of n

Solving the subtraction of the fractions and simplifying:
