I am assuming you were supposed to be using Pythagorean theorem. So I will help you solve it that way. As you know Pythagorean theorem needs a right angle and the three sites.Because the line is a tangential wine that means that it is perpendicular to a radius; therefore, that’s the right angle. r and 120 are legs, a & b. The hypotenuse is 80 plus what? How long? 80+ r.
Pythagorean Theorem:
A^2 + b^2 = c^2
120^2 + r^2 = (80 + r)^2
(120)(120) + r^2 = (r + 80)(r +80))
14400+ r^2 = r^2 + 160r + 6400
8000=160r
R=5 ft.

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 . . . . . . . . . . . . 0.001037

white males

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

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

non hispanic white population

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
