Answer: 125lb < M < 155 lb

Step-by-step explanation:

The mean mass is 140 lb, and the deviation must be less than 15 pounds (exactly 15 is not accepted).

Then (140lb + 15lb) is not alowed, and (140lb - 15lb) is not alowed.

Then we can define M = mass.

We have the two equations:

M < 140lb + 15lb

M < 155lb

And

M > (140lb - 15lb)

M > 125lb

If we write these two relations togheter, we get:

125lb < M < 155 lb

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
