Question

The wild dog population has a death rate of 0.1 for a given period. If the initial population size for a given region was 90 what is the total number of deaths occured in the given period?

• A. 7
• B. 6
• C. 9
• D. Data insufficient

Answer 1

The correct option is C 9

Death rate is the ratio of the number of individuals who died in a population in a given amount of time to the initial total population.

Therefore,
$0.1=\frac{\mathrm{Number}\mathrm{of}\mathrm{dead}\mathrm{individuals}}{90}$

$\mathrm{No}.\mathrm{of}\mathrm{dead}\mathrm{individuals}=0.1\times 90$
$=9$
