The company's expectation is $486.26.
Since the probability that an 80-year-old male in the U.S. will die within one year is approximately 0.069941, to determine, if an insurance company sells a one-year, $ 12,000 life insurance policy to such a person for $ 495, what is the company's expectation, the following calculation must be performed:
- (12000 x 0.069941 / 100) + (495 x (100 - 0.069941) / 100) = X
- -8.39292 + 494.65379205 = X
- 486.26 = X
Therefore, the company's expectation is $486.26.

Answer:
Step-by-step explanation:
let x = how many joe sold
let 4x = how many abe sold
900 = x + 4x
900 = 5x
180 = x
joe sold 180
and abe sold 4x
4(180) = 720
hat means Abe sold 720 trucks

180 + 720 = 900
our answer is right
Answer:
5
Step-by-step explanation:
substitute the given values for p and q into the expression
= = = 5
Eqt 1 = 4a-5b=7
eqt 2 = 4a+5b=17
eqt1+eqt2= 8a=24
a=3 then 4*3-5b=7
so b=1
