Answer:

the answer is 2.4 million

Step-by-step explanation:

In order to find the rate of change, you first must find the amount that the population grew in the time period:

314-302 = 12

Now you need to calculate the number of years:

2012-2007 = 5

Lastly, divide the amount of change by the number of years:

12/5 = 2.4

The population grew by 2.4 million people per year. Hope this helps! :)

Answer:

The coordinates of the end point B are (14 , 8)

Step-by-step explanation:

let B(x , y)

M midpoint of A and B

⇔ 8=(x+2)/2 and 11=(y+14)/2

⇔ 16=x+2 and 22=y+14

⇔ x=14 and y=8
