Which set of ordered pairs does not represent a function? \{(-8, 6), (-7, -7), (7, -9), (0, 6)\}{(−8,6),(−7,−7),(7,−9),(0,6)} \{(-9, 9), (-3, 4), (3, 9), (-2, 1)\}{(−9,9),(−3,4),(3,9),(−2,1)}
\{(7, -2), (-5, 6), (5, 0), (3, -2)\}{(7,−2),(−5,6),(5,0),(3,−2)} \{(-9, 1), (2, 0), (8, -2), (2, -6)\}{(−9,1),(2,0),(8,−2),(2,−6)}

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
