Answer from: yettionajetti

2(x - 10)(x + 10)

Step-by-step explanation:

Given

2x² - 200 ← factor out 2 from each term

= 2(x² - 100) ← x² - 100 is a difference of squares and factors as

x² - 100 = x² - 10² = (x - 10)(x + 10), hence

2x² - 200 = 2(x - 10)(x + 10)

Answer from: sfritz6456

Step-by-step explanation:

If your equation is 2x^2-200 and you're to factor it, the first thing you do is set the expression equal to 0 so you can solve for x.

2x^2-200=0

There's a couple of different ways in which to approach this. You can factor out a 2:

2(x^2-100)=0

and solve it from there. The Zero Product Property says that if the equation is equal to 0, then either 2 has to equal 0 or x^2-100 has to equal 0. We know that 2 does not equal 0, so x^2-100=0

Add 100 to both sides in the equation:

x^2=100

and then take the square root of both sides. Because this is a second degree polynomial, we expect to have 2 solutions, and we do. Don't forget that when you take the square root of a number you have to alow for both the positive and the negative of the result. Our factored form of the given equation then is that x = 10 and x = -10.

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:

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
