E(X) = 0(0.7) + 1(0.2) + 2(0.1) = 0.2 + 0.2 = 0.4
The expected daily loss due to blackouts = 0.4 * $500 = $200
Var(X) = 0(0.7 - 0.4)^2 + 1(0.2 - 0.4)^2 + 2(0.1 - 0.4)^2 = 0.04 + 0.18 = 0.22
The expected daily variance due to blackouts = 0.22 * $500 = $110
Answer:5. is 500%
Step-by-step explanation:
x + 15 = 24
subtract 15 from both sides
x = 24 - 15 = 9
Answer:
3/2 times as far
Step-by-step explanation:
Mai's distance divided by Noah's distance will give you your answer.
6.75 divided by 4.5 is 1.5 which is 3/2 as a decimal.
Answer:
1225π
Step-by-step explanation:
The question concerns the volume of the cylinder.
The formula of the volume is:
, where r is the radius and h is the height.
Plugging the given numbers into the formula, we find that:
The result - 1225π shows that the cylinder can be filled fully with that given amount.
