I think that this is just showing how you can make different percentages by multiplying/dividing by specific numbers.

A company that sells annuities must base the annual payout on the probability distribution of the length of life of the particip

Svetlanka [38]

Answer:

Step-by-step explanation:

Let X be length of life of the participants in the plan.

Given that X is N(68,3.5)

We convert this to standard normal score z using

$z=\frac{x-68}{3.5}$

a) proportion of the plan recipients that would receive payments beyond age 75= $P(X\geq 75) = P(Z\geq 2)\\= 0.025$

b) proportion of the plan recipients die before they reach the standard retirement age of 65= $P(X\leq 65) = P(z\leq -0.86)\\=0.5-0.2764\\=0.2236$

c) x for 86% ceased

Answer:

$\square\quad{y=\dfrac{1}{2}x+4}\\\\\square\quad{\dfrac{y-5}{x-2}=\dfrac{1}{2}}$

Step-by-step explanation:

The slope of a line is the same everywhere, so an equation can be written making use of that fact.

$\dfrac{y-y_1}{x-x_1}=\dfrac{y_2-y_1}{x_2-x_1}\\\\\dfrac{y-5}{x-2}=\dfrac{7-5}{6-2}=\dfrac{2}{4}\\\\\boxed{\dfrac{y-5}{x-2}=\dfrac{1}{2}}$

Cross-multiplying gives ...

2(y -5) = x -2

2y -10 = x -2 . . . eliminate parentheses

2y = x +8 . . . . . . . add 10; next, divide by 2

$\boxed{y=\dfrac{1}{2}x+4}$

These equations match choices B and D.
