Goshia [24]

Answer:

The correct answer is 327.78.

Explanation:

A mortality rate refers to the determination of the rate of the occurrences of deaths in a given population in the course of a particular time period. The formula for finding the mortality rate is:  

Deaths taking place in a given time duration / the size of the populace among which the deaths have taken place × 10ⁿ

The given population of the country is 250 million

The number of individuals died due to a certain disease is 819450

Thus, the mortality rate per 100000 can be calculated as:  

819450 / 250000000 × 100000 = 327.78 deaths per 100,000 people.
