Answer from: kdd46

Choice B) 15x, -x, and 33x

Explanation:

Like terms are when we have the same variable attached to the number. The variable must have the same exponent as well.

For instance, 2x and 3x are like terms since they both have x. Something like 7x and 8x^2 are not like terms because the exponents don't match.

Terms like 17y and 17 are not like terms because the second term doesn't have a y tacked on. If you have nothing but constants, then those are like terms as they all have the same thing in common in that they don't have a variable attached to them.

With all this in mind, we can see that 15x, -x, and 33x is the answer since each have x as part of the variable term. The exponents are all the same (all being 1).

step-by-step explanation:

i found the life tables for the year 2012.

life table of males at age 30. probability of dying between ages x and x+1

total population:

29–30 . . . . . . . . . . . . 0.001030

30–31 . . . . . . . . . . . . 0.001061

males:

29–30 . . . . . . . . . . . . 0.001420

30–31 . . . . . . . . . . . . 0.001448

white population

29–30 . . . . . . . . . . . . 0.001005

30–31 . . . . . . . . . . . . 0.001037

white males

29–30 . . . . . . . . . . . . 0.001372

30–31 . . . . . . . . . . . . 0.001399

non hispanic white population

29–30 . . . . . . . . . . . . 0.001083

30–31 . . . . . . . . . . . . 0.001116

non hispanic white males

29–30 . . . . . . . . . . . . 0.001477

30–31 . . . . . . . . . . . . 0.001503

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
