Given:

Consider the population of California = $3.9\times 10^7$

Consider the population of Maine = $1.3\times 10^6$

To find:

The difference between the population of California and Maine.

Solution:

We have,

Population of California = $3.9\times 10^7$

Population of Maine = $1.3\times 10^6$

Difference between the population of California and Maine is

$\text{Difference}=3.9\times 10^7-1.3\times 10^6$

$\text{Difference}=3.9\times 10^7-(0.13\times 10)\times 10^6$

$\text{Difference}=3.9\times 10^7-0.13\times 10^7$

$\text{Difference}=(3.9-0.13)\times 10^7$

$\text{Difference}=3.77\times 10^7$

Therefore, the correct option is D.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

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
