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
$15 + $32.50 + 8% = $51.30
15 + 32.50 = 47.50
8% × 47.50 = 3.80
47.50 + 3.80 = 51.30
Answer:
C (x ≥ -6)
Step-by-step explanation:
<u>Algebraic:</u>
The domain of
is
. When transformed 6 units to the left, it becomes 
<u>Graphically:</u>
As shown in the attached graph,
.
Percent means parts out of 100
105%=105/100=1.05
'of' means multiply
105% of 260=1.05 times 260=273
