Answer:
about $145.33
Step-by-step explanation:
Consider a group of 15 customers. They will pay ...
15 × $258 = $3870
in premiums each year.
One-third of those, 5 customers, will submit claims for fillings, so will cost the insurance company ...
5 × $110 = $550
And 80% of them, 12 customers, will submit claims for preventive check-ups, so will cost the company ...
12 × $95 = $1140
The net income from these 15 customers will be ...
$3870 -550 -1140 = $2180
Then the average income per customer is this value divided by the 15 customers in the group:
$2180/15 = $145.33
_____
<em>Alternate solution</em>
Above, we chose a number of customers that made 1/3 of them and 4/5 of them be whole numbers. You can also work with one premium and the probability of a claim:
258 - (1/3)·110 - 0.80·95 = 145.33

Answer:
Critical points are 1 and -1
Maximum at x=1
Minimum at x=-1
Step-by-step explanation:
We are given that a function
on (
)
We have to find the critical points of the function.
To find the critical point we will differentiate function w.r.t x and then substitute f'(x)=0
Therefore, the critical points of the given function are 1 and -1.
When we goes from 0 to 2 then the sign of derivative change from positive to negative .Therefore, function has local maximum at x=1.
When we goes form -2 to 0 then the sign of derivative change from negative to positive .Hence , function has local minimum at x=-1
Hence, critical points are local maximum and local minimum .
still, if you have any doubt ask me!

answer is 3.24 grams per cubic centimetre. As a matter of fact, the
lunar soil’s mean density may range from 2.90 to 3.24 g cm-3 which highly
depends on the type of ingredients present in its resource materials.</span>
