The answer is 2 raccoons per square meter.
The math is very clear. It can be solved using proportion.
If 20 raccoons live in 10 square meters, how many of them will live in 1 square meter:
20 raccoons : 10 m² = x raccoons : 1 m²
⇒
⇒ x =
⇒ x = 2
So, a population density is 2 raccoons per square meter.
Answer is False.
Any investigation normally begin with an observation. Something that catches the attention. A logical problem-solving approach used by scientists is called the scientific method.
Asking question is the step of a scientific method after observation is made. Then comes hypothesis. A hypothesis is prospective answer to the question which is somehow going to be tested.
