F(x) = 3x - 5x + 40: f(2).

f(2) = 36

Step-by-step explanation:

Hello!

To find f(x), plug in 2 for x in the original equation.

Solve:

The final solution is 36.

Y = 36   or  F = -x+20

^ ^ ^ Not sure about what ur asking, so I put in 2 versions that I know of.

Step-by-step explanation:

Write out the equation:

f(2) = 3x - 5x + 40

If X is 2, then write the equation out as:

Y = 3(2) - 5(2) + 40

Now multiply:

Y = 6 - 10 + 40

Simplify:

Y = 36

Let's solve for f.

f(2)=3x−5x+40

Divide both sides by 2.

2f/2 = −2x+40/2

f=−x+20

f=−x+20

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497

just sum

10 + 10 = 20
