A population has 1000 individuals. Over a period of 1 year, 500 new individuals are born. Which equation shows how to calculate the birthrate of this population?

A. [tex]500 \div 1000=0.5[/tex]
B. [tex]1000 \div 500=2[/tex]
C. [tex]1000 \times 0.5=500[/tex]
D. [tex]1000+500=1500[/tex]



Answer :

To determine the birthrate of a population, we calculate the fraction of new births compared to the initial population.

The birthrate is calculated by taking the number of new births and dividing it by the initial population.

We start with the given data:
- Initial population: 1000 individuals
- New births: 500 individuals

We need to find the birthrate using the formula:
[tex]\[ \text{Birthrate} = \frac{\text{Number of new births}}{\text{Initial population}} \][/tex]

Substituting the given values:
[tex]\[ \text{Birthrate} = \frac{500}{1000} \][/tex]

This simplifies to:
[tex]\[ 0.5 \][/tex]

Therefore, the equation that shows how to calculate the birthrate of this population is:
A. [tex]\( 500 \div 1000 = 0.5 \)[/tex]

The correct answer is option A.
