Problem

Use the graph on the right to estimate the death rate for 65 -year-olds. Assuming that there were about 12.9 million 65 -year-olds, how many people of this age could be expected to die in a year? The estimated death rate for 65 -year-olds is 18 deaths per 1000 people. (Round to the nearest whole number as needed.) Assuming that there were about 12.9 million 65 -year-olds, $\square$ people of this age could be expected to die in a year. (Simplify your answer.)

Solution

Step 1 :Given values are death rate of 18 per 1000 people and a total population of 12.9 million 65-year-olds.

Step 2 :Convert the total population from millions to the actual number, which is \(12.9 \times 10^6 = 12900000.0\).

Step 3 :Calculate the number of deaths by multiplying the death rate per 1000 people by the total population. This gives \(\frac{18}{1000} \times 12900000.0 = 232200\).

Step 4 :Round the number of deaths to the nearest whole number, which remains 232200.

Step 5 :Thus, \(\boxed{232200}\) people of this age could be expected to die in a year.
