Answer from: Amyra2003

The answer to your question is the last option (-2x² - 3)(4x + 1)

Step-by-step explanation:

Expression - 8x³ - 2x² - 12x - 3

Order the terms - 8x³ - 12x - 2x² - 3

Process

1.- Factor the first two terms and the last two terms

(-8x³ - 12x²) + (-2x - 3)

Common factor of the first group -4x

Common factor of the second group -1

2.- Factor each group

First group -4x(2x² + 3)

Second group -1 (2x² + 3)

3.- Factor again by common factor

-4x(2x² + 3) - 1(2x² + 3)

(2x² + 3)(-4x - 1) or -(2x² + 3)(4x + 1) or (-2x² - 3)(4x + 1)

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:

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

males:

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
