Answer:

<em>398 deaths were caused by Alzheimer.</em>

Explanation:

Proportionate mortality rate (PMR) gives the proportion of deaths in a given population over a period of time, this can be linked to various causes.

Mathematically PMR is reoresented below;

PMR = $\frac{D_{s} }{D_{t} }$ X 100

where $D_{s}$ = No. of death from a specific cause (In our case Alzheimier )

$D_{t}$ = Total No. of death at a given period

from the question the parameters were given except the number of death from Alzheimier

1.87 = $\frac{D_{s} X 100}{21,270}$

multiply both side by 21,270 to isolate $D_{s}$

$D_{s} X 100$ = 1.87 x 21,270

Divide both side by 100 to obtain $D_{s}$

$D_{s}$ = $\frac{39774.9}{100}$

$D_{s}$ = 397.749

since dead people can not be divided
