Question

A population has 1000 individuals. Over a period of 1 year, 200 new individuals are born. Which equation shows how to calculate the birthrate of this population?



A. 1000 × 0.2 = 200
B. 1000 + 200 = 1200
C. 200 ÷ 1000 = 0.2
D. 1000 ÷ 200 = 5

Answer 1

the way you find the birth rate is dividing the number of births to the population so your answer would be c

Answer 2

Answer: C. 200 ÷ 1000 = 0.2

Explanation:

Birth rate is defined as the number of individuals born every year per 1000 people in a population.

Thus Birth rate=$\frac{\text {Number of individuals born}}{\text {Original population}}$

Thus Birth rate=$\frac{200}{1000}=0.2$

Thus birth rate is given by 200 ÷ 1000 = 0.2
