[4C-04] An insurance policy reimburses a loss with a deductible of 5. That is, if a loss is less than 5, policy will pay zero. I

user100 [1]

Answer:

-3

Step-by-step explanation:

Given that an insurance policy reimburses a loss with a deductible of 5. That is, if a loss is less than 5, policy will pay zero. If it is more than 5, then the policy will pay (loss - 5).

We have distribution of y as

$f(y) = \frac{2}{y^3} , y>1\\ =0 otherwise$

expected value of the benefit paid under the insurance policy

= $E(Y-5)\\=E(Y)-5$ , by linearity property of expectation.

$E(y) = \int\limits^\infty_1 {y(\frac{2}{y^3} )} \, dy\\=\frac{-2}{y} \\=-0+2\\=2$

Hence expected value of the benefit paid under the insurance policy

=2-5 =-3

castortr0y [4]

Answer:

Answers are 3 AM ; 10 , 54

Step-by-step explanation:

We are given a graph.

Recording of temperature starts from 9 PM.

So from Graph,

Temperature ate 9 PM = 59°F

Temperature ate 11 PM = 54°F

Temperature ate 1 AM = 51°F

Temperature ate 3 AM = 50°F

Temperature ate 5 AM = 51°F

Temperature ate 7 AM = 54°F

Temperature ate 9 AM = 59°F

So, At 3 AM the water is at its lowest temperature.

and

After 10 hours passed, the temperature of the lake is 54°F.

Therefore, Answers are 3 AM ; 10 , 54
