7. D) 180

7. C) 24%

7. D) 2 out of 9

7. D

Step-by-step explanation:

36 doesn't go into 5

45 doesn't go into 4

60 doesn't go into 9

180/4 = 45

180/3 = 60

180/5 = 36

180/9 = 20

We can make this problem even easier by converting the denominator from 25 to 100. This can be done with multiplication (x4)

Whatever you do to the denominator, you must also do to the numerator, so if we multiply both sides by 4, we get 24/100, which is equivalent to .24

total: 81 pieces of jewelry

18/81 or 2/9 (divide numerator and denominator both by 9)

.67 = 67/100

.607 = 607/1000 or 60.7/100

.07 = 7% or 7/100

.067 = 6.7% or 6.7/100

the answer is letter "D" (180)

hope it helped! :)

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:

non hispanic white population

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

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

non hispanic white males

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

hope this is what you were asking for!
