I did the math and (6,26) is the correct answer.
The correct answer is the choice that you have selected, the third choice.
When, we are looking at the residuals for a regression line, we always want to see the points balance like in the third choice. This means that the equation that we found is right in the middle of the points.
20% of 2100 is 420
So the tax is $420
Then 2100-420= 1680
So he has $1680 left after paying the tax.
The answer to that would be D. 54,299
Recall the formula for area of a rectangle
A = LW
A = area of rectangle
L = length of rectangle = 6
W = width of rectangle
Also, recall the formula for Perimeter of a rectangle
P = 2L + 2W
P = perimeter of rectangle = 20
We have L=6 and P=20. Use these to solve for W in the perimeter formula.
P = 2L + 2W
20 = 2(6) + 2W
20 = 12 + 2W
8 = 2W
4 = W
Thus, L = 6 and W = 4. Use these measurements to solve for A.
A = LW = 6 * 4 = 24 in^2
