Answer:
$112.08 every year.
Step-by-step explanation:
Let's suppose a game in which we bet a certain amount of money ''A'' to a certain result and the probability of that result is ''p''. If the prize that we get is ''P'' therefore the expected value of gain is :
Now,let's suppose that the female is ''betting on her death'' ⇒
P(she survives) = 0.999592
P(she doesn't survive) = 1 - 0.999592=
E(25-year old female) = 
The negative sign of E is important.It means that every year the 25-year old female will lose $112.08.
Therefore, the expected value of this policy to the insurance company is $112.08 every year.

(a) 8(4x+3) > -1 + 7x
32x + 24 > -1 + 7x
32x - 7x > -1 -25
25x >-26
x > -26/25
(b) 167 < 6 + 7(2 - 7r)
167 < 6 + 14 - 49r
49r < 6 + 14 - 167
49r < - 147
r < - 3
(c) 8x + 40 > -8 ( 1 - 7x)
8x + 40 > -8 + 56x
56x - 8x < 48
48x < 48
x < 1
(d)5( 6 + 3r) + 7 > 127
30 + 15r + 7 > 127
15r > 127 - 37
