A professional organization sells term life insurance and major medical insurance. Of those who have just life insurance, 60% wi

kherson [118]

Answer:

The answer is "0.765 and 0.2353".

Step-by-step explanation:

Please find the complete question in the attached file.

In point a:

P(a substantive term only) $=0.75-0.2 =0.55$

P(major health insurance only) $= 0.45-0.20=0.25$

P(both) $= 0.20$

P(renewal) =P(insurance and renewal term only)+P (substantial and renewable health insurance only)+P (both and renew)

$=0.55\times 0.7+0.25 \times 0.8+0.2 \times 0.9 \\\\ =0.765$

In point b:

In reality, the probability of having both life and major medical insurance provided the policyholder would renew next year

$= \frac{\text{P(both and renew)}}{\text{P(renew)}}$

$=\frac{0.2\times 0.9}{0.765}\\\\=0.2353$

Solve for x: 3(x+1)=5(x-2)+7

mojhsa [17]

Answer:

x = 3

Step-by-step explanation:

3 ( x + 1 ) = 5 ( x- 2 ) + 7

Expand

3 x + 3 = 5 x - 10 + 7

Minus 5 x from both sides

- 2 x + 3 = - 10 + 7

Minus 3 from both sides

- 2 x = - 10 + 4

Simplify

- 2 x = - 6

Divide both sides by - 2

x = 3
