It’s definitely NOT D, as the distributive means distributing something.

Example of a distribution problem

7(5+2)
You need to distribute 7 into 5 and 2. (7•5 ) + (7•2)

The answer is A.

The are the same regardless of their value.

Hope that helps!

Suppose you are studying a population with the following characteristics: Birth rate = 14 per 1,000/year Death rate = 6 per 1,00

Nutka1998 [239]

Answer:

12 per 1,000 / year would be population growth

Step-by-step explanation:

To know the population growth it is important to know what it contributes to its growth and that it decreases it.

Birth rate ==> increases growth

Death rate ==> decreases growth

Immigration rate ==> increases growth

Emigration rate ==> decreases growth

Now it only remains to add those that increase growth and subtract those that decrease, like this:

14 per 1,000 / year - 6 per 1,000 / year + 5 per 1,000 / year - 1 per 1,000 / year = 12 per 1,000 / year

12 per 1,000 / year would be population growth
