Question

City there are 244,000 48-year-olds. Based on the table below howmany are not expected to be alive in a year?

Answer 1

SOLUTION:

Case: Number of deaths

Method:

First, we add the total number of deaths

$\begin{gathered} 63+79+91+99+103+106+110+113+115+117+118+120+123+127+132+315+341+371+405+443 \\ =3491 \end{gathered}$

Next, we subtract from the total number of people alive

$\begin{gathered} 2000000-3491 \\ =1996509 \end{gathered}$

If there were 244,000 48-year olds,

The scale factor will be:

$\begin{gathered} =\frac{244000}{100000} \\ =2.44 \end{gathered}$

Hence the number of people expected NOT to be alive is:

$\begin{gathered} 3491\times2.44 \\ =8518.04 \end{gathered}$

Final answer:

8519 people approximately
