Answer:

25

Step-by-step explanation:

Suppose the claim size of an auto collision insurance, X, is uniformly distributed on the interval $1,000 to $10,000. What is th
timurjin [86]

Answer:

35.35%

Step-by-step explanation:

If there were no deductibles, the expected claim payment would be:

E(X) = \frac{10,000 +1,000}{2} \\E(X) =\$5,500

If the collision insurance claim is under $2,000, then the insurer would not pay anything, but if X > $2,000, then the insurer would pay X - $2,000. The new expected value is:

E_2(X)=\frac{2,000-1,000}{10,000-1,000} *0+\frac{10,000-2,000}{10,000-1,000}*\frac{(2,000-2,000)+(10,000-2,000)}{2} \\E_2(X)=\frac{8}{9}*\frac{0+8,000}{2}\\ E_2(X)=\$3,555.56

The percentage reduction on the claim payment is:

P=(1-\frac{E_2(X)}{E(X)})*100 \\P=(1-\frac{3,555.56}{5,500})*100\\P=35.35\%

There was a 35.35% reduction.

Mike earns $15 for each hour he work plus a $25 bonus. How much does he earn in 10 hours of work?
MakcuM [25]
<h3>Hello there!</h3>

We are trying to find how much Mike earns when he worked for 10 hours

Lets make an equation out of the given information in the question.

We know that:

  • Earns $15 each hour
  • $25 bonus

We would format it as y = mx + b

Our equations would be y = 15x + 25

"x" being the amount of hours he worked

We know that he worked 10 hours, so we would plug 10 into x.

Then, we can solve.

y = 15(10) + 25

y = 150 + 25

y = 175

<h3>Answer: $175</h3><h3>I hope this helps!</h3><h3>Best regards,</h3><h3>MasterInvestor</h3>
