In 2007, the US population was 302 million people. In 2012, and 314 million. What was the rate of the population change per year?

Answers

The correct answer is:

2.4 million.

Explanation:

To find the rate of change, first we find the amount that the population grew in the time period:

314-302 = 12

Now we calculate the number of years:

2012-2007 = 5

Divide the amount of change by the number of years:

12/5 = 2.4

The population grew by 2.4 million people per year.
314 - 302 =12 / 5 = 2.4,

the population grows 2.4 percent of people a year.

Step-by-step explanation:

Your aunt bought a new car. After three months of car payments she owed a total of $22,275 to the bank for the car loan. After 12 months, she owed $18,900 to the bank for the car loan. What was her average payment rate on the principal of the car loan during this time?

Answers

Given:
Balance after 3 months = 22,275
Balance after 12 months = 18,900

$22,275 - $18,900 = $3,375

12 months - 3 months = 9 months

3,375 / 9 months = $375 per month.

375 x 12 = 4,500
4,500 + 18,900 = 23,400 principal amount.

375 / 23400 = 0.016 
0.016 x 100% = 1.60%

The principal of the car loan is $23,400
The interest rate of the car loan is 1.60%
The monthly payment is $375.

Answer:

You can find the rate of change by dividing the difference in the principal owed by the difference in the number of months.

18,900 – 22,275 / 12 – 3 = -375

The average payment is $375 per month.

Brain was asked to round 4.44 to the nearest tenth and said it was 4.5 Is he correct?Why or Why not?

Answers

Brian (I think you meant Brian haha..) is incorrect because the tenth place is the number right after the decimal which is a 4. If you are rounding to the tenth place that means that you have to look at the number to the right of that, which is 4. 5 and up means you round up and 4 and down means you round down. This is a 4, so you keep the 4 after the decimal and get rid of the last 4. Therefore, when rounded it would be: 4.4.
Hope this helped! Good luck! :)
The answer is 4.4 hope i helped :)
