It is given that:

Kendra has 3 times as much money as her two younger siblings.

i.e. the sum of money both the siblings , he has three times of that sum.

Her younger brother has $10 and her younger sister has $4.

This means that the sum of money both younger siblings has is:

$ 10+$ 4 = $ 14.

Now, the money Kendra has is: 3 times of $ 14

i.e. 3×14=$ 42.

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.

Answer:A rubric is a grading tool that describes the criteria, or "what counts," for the assignment. It also describes each of the criteria according to gradations of quality, with descriptions of strong, middling, and problematic student work. The criteria are listed in the column on the left. The numbers in the top row indicate quality, with 3 being the best. The number 0 is something everyone wants to avoid.
