Answer and Step-by-step explanation:

The computation of annual and quarterly mortality rates per 100,000 population is shown below:-

Quarterly mortality rates are


= (Deaths)/(Population\ in\ the\ city)* Population

For the first quarter


= (54)/(450,000)* 100,000

= 12 death per 100,000 population

For the second quarter


= (43)/(450,000)* 100,000

= 9.5 death per 100,000 population

For the third quarter


= (35)/(450,000)* 100,000

= 7.7 death per 100,000 population

For the fourth quarter


= (39)/(450,000)* 100,000

= 8.6 death per 100,000 population

Now the annual mortality is


= (Deaths)/(Population\ in\ the\ city)* Population


= (171)/(450,000)* 100,000

= 38 death per 100,000 population
