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

The function 
Now since you need to find the value of this new function at the point x=3, replace x by "3" in the expression above and perform the calculation:

Answer:
1r5
Step-by-step explanation:
if 5+t=12,
then t=12-5
t=7
if 12/7, then the answer would be
Answer:
The width is 10 and the length is 14.
Step-by-step explanation:
To draw this conclusion, first use the equation<em> A = lw = 140
.</em>
Remember the length is six less than twice the width, in other words, the length equals 2 time the width minus 6:<em> l = 2w - 6
</em>
Now you want to substitute numbers in:
140 = (2w - 6)(w)
140 = 2w^2 - 6w
2w^2 - 6w -140 = 0
w^2 - 3w - 70 = 0
Factorable by inspection!
(w - 10)(w + 7) = 0
w = 10
<em>w = -7 (nonsense - ignore)
</em>
I = 14
Answer:
5
Step-by-step explanation:
The numbers on the clock are separated by 30°, so the number 4 is at 120° after 12. The next number is 5, at 150°.
