State the domain: g(x)=-2+the square root of (1-x). explain how i get the answer.

First of all, thanks for using parentheses. Your doing so made the problem so much clearer than it would have been otherwise.

g(x) = -2 + √(1-x).

What's the domain of this function? Focus on √(1-x). Recall that the domain of the square root function is [0, infinity); in other words, the domain consists of the set of all real numbers equal to or greater than zero (0).

What's the domain of √(1-x)?

Borrowing the comments above, (1-x) must be ≥ 0.

Let's solve this inequality: Add x to both sides. We get 1 - x + x ≥ 0 + x.

Then x ≤ 1 is the domain of the given function.

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
