sweet-ann [11.9K]

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

<em></em>D_{s}<em> </em>
