<h3>Answer:  10</h3>

============================================

Work Shown:

First add up all the ages

9+13+9+10+10+9+10+10+11+9 = 100

Then divide that sum by 10, since there are 10 values we added up

100/10 = 10

The average age is 10 years old.

High population density can cause increased competition for resources such as food or shelter, while a low population density ca
krek1111 [17]

Answer:

The region with the highest population density is Binky Lee

The region with the lowest population density is Cheslen

Step-by-step explanation:

we know that

The <u><em>population density</em></u> is the number of people per unit of area

so

Find out the population density for each region

<em>Bear Creek</em>

\frac{462}{112}= 3.70\ people/acre

<em>Binky Lee</em>

\frac{12,624}{3,412}= 4.13\ people/acre

<em>Cheslen</em>

\frac{3,537}{1,263}= 2.80\ people/acre

<em>Crow's Nest</em>

\frac{2,142}{612}= 3.5\ people/acre

so

Cheslen < Crow's Nest < Bear Creek < Binky Lee

therefore

The region with the highest population density is Binky Lee

The region with the lowest population density is Cheslen
