36 inches = 3 feet ( 36/12 = 3)

3/48 = 1/16 ratio

1.25*(t)+7=43.25

To solve the 2nd one, you must do 43.25 - 7 = 26.25

36.25 divided by 1.25 = 29

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

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

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

F(x)=x^2+8x-10 find f(a)+5

Papessa [141]

Answer:

We conclude that:

f(a) + 5 = a² + 8a - 5

Step-by-step explanation:

Given

The function is given by

f(x) = x²+8x-10

To determine

f(a)+5

In order to determine f(a)+5, first, we need to determine f(a).

Now substitute x = a in the function f(x) = x²+8x-10

f(a) = (a)² + 8(a) - 10

f(a) = a² + 8a - 10

Thus,

f(a) + 5 = (a² + 8a - 10) + 5

f(a) + 5 = a² + 8a - 5

Therefore, we conclude that:

f(a) + 5 = a² + 8a - 5

Karen is at least 4 years more than twice mary's age (m). Karen is 46 years old. Write a simplified inequality that represents m

Margarita [4]

Answer:

46 ≥ 2m + 4

m ≥ 21

Step-by-step explanation:

At least is ≥

Karen's age = 46 years old

Mary's age = m years old

Karen is at least 4 years more than twice mary's age (m).

46 ≥ 2m + 4

46 - 4 ≥ 2m

42 ≥ 2m

m ≥ 42/2

m ≥ 21
