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