The population of a community is known to increase at a rate proportional to the number of people present at time t. The initial population P0 has doubled in 5 years. Suppose it is known that the population is 12,000 after 3 years. What was the initial population P0?

P(0) = 7,917

Step-by-step explanation:

The population of the community is given by the following formula:

In which P(0) is the initial population and r is the growth rate.

The initial population P0 has doubled in 5 years.

This means that

Which lets us find r.

Applying the 5th root to both sides

So

Suppose it is known that the population is 12,000 after 3 years.

With this, we find P(0)

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
