Problem 4: The idea of insurance is that we all face risks that are unlikely but carry high cost. Workers' compensation insurance provides for the cost of medical care, rehabilitation, and other
related expenses for injured workers. In a given year, most workers will not have any work
injury, some will have minor injuries, and a few will die or become permanently disabled.
Insurance spreads the risk: We all pay a small amount, and the insurance policy pays a large
amount to these few extreme claims. The National Academy of Social Insurance reports that the
mean workers' compensation claim cost in a year is u = $439 per insured worker, and the
standard deviation is o = $20,000. The distribution of losses is strongly right-skewed: Most
policies have no loss, but a few have large losses, up to millions of dollars.
a) An insurance company plans to sell workers' compensation insurance for S439 plus
enough to cover its administrative costs and profits. Explain clearly why it would be
unwise to sell only 12 polices. Then explain why selling thousands of such policies is a
safe business.

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1

step-by-step explanation:

answer: 75°

step-by-step explanation:

∠esk is the supplement of ∠edk, so is 100°. ∠esd = 1/2·arc ed, so is 25°.

since ∠esk = ∠esd + ∠dsk

you have 100° = 25° + ∠dsk . .

fill in known values 75° = ∠dsk . . . . .

subtract 25°
