6/2
Step-by-step explanation:
(y2-y1)/(x2-x1)
4-(-2) over 1-(-1)
4+2 over 1+1

The balance of the loan at 14 months= $10,561.25
It would take a total 23 months to pay off the loan.
The total amount of money paid for the car is = $9,052.5
<h3>Calculation of loan compounded monthly</h3>
The total loan for the car = $8,500
The rate at which the loan is compounded monthly is
= 6.5%
The monthly payment for the loan = $390
- To calculate the balance of the loan at 14 months;
Find the simple interest
= P×T×R/100
= 8,500 × 1 × 6.5/100
= 55,250/100
= $552.5
If 12 months = 8,500 + 552.5
14 months = X
make X the subject of formula,
X = 14 × 9052.5/12
X= 126,735/12
X = $10,561.25
- To calculate the period of time it will take to pay off the loan
The amount paid monthly = $390
The amount to be paid for the loan with interest = 8,500 + 552.5 = $9,052.5
If 1 month = $390
× month = $9,052.5
Make X the subject of formula,
X = $9,052.5/$390
X= 23 months
The total amount of money paid for the car is already calculated which is through the simple interest
= P×T×R/100
= 8,500 × 1 × 6.5/100
= 55,250/100
= $552.5
- Total amount of money paid for the car
= 8,500 + 552.5
= $9,052.5

The ACT score was better since the z-score of the ACT is greater than the z-score of the SAT. Then the correct option is B.
<h3>What is a normal distribution?</h3>
It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.
The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.
The z-score is given as
In 1985, the average ACT score was 18 with a standard deviation of 6.
Also in 1985, the average SAT score was 500 with a standard deviation of 100.
Dr. Robertson took both tests in 1985 and scored a 26 on the ACT and a 620 on the SAT.
Then the z-score of the ACT will be
Then the z-score of the SAT will be
Then the ACT score was better since the z-score of the ACT is greater than the z-score of the SAT.

If x = 3 is a solution, (x - 3) is a factor of f(x).
2x³ + x² - 25x + 12 ÷ (x - 3) [by long division] = 2x² + 7x - 4
so f(x) = (x - 3)(2x² + 7x - 4)
f(x) = (x - 3)(2x - 1)(x + 4)
so 'zeros', or more correctly solutions, are: x = 3, x = 1/2 and x = -4.
[by setting each of the factors equal to 0 and solving for x].
