Slope is x so it’s -1/5

Answer:
Step-by-step explanation:
Use the Single column to solve this problem.
First you need to figure up her taxes and then subtract the tax credit.
She has a taxable income of 17000. This puts her in the 15% bracket.
<u>First we need to get the % owed on the first 9275 dollars that is taxable.</u>
.10 * 9275 = 927.50
<u>Next we need to get the % owed on the rest of her money, which is in the 15 % bracket</u>
.15 * (17000 - 9275) = 1158.75
<u>Finally, sum up our taxes on the money and then subtract our tax credit, which is 2500</u>
(927.50 + 1158.75) - 2500
(2086.25) - 2500 = -413.75
Since you have a negative number, the government owes you $413.75 dollars. If it was not a negative number, you would owe the government.
Answer:
b = - 3.7
Step-by-step explanation:
here are the data values:
x y XY X²
14 46 644 196
15 49 735 225
16 37 592 256
17 42 714 289
18 37 666 324
19 31 589 361
20 25 500 400
21 23 483 441
22 20 440 484
23 15 345 529
24 12 288 576
now we are required to find the summation (total) of all values of X, Y, XY and X².
∑X = 209
∑Y = 337
∑XY = 5996
∑X² = 4081
The formular for finding b is given as:
b = n∑XY - (X)(Y) / n∑X² - (∑X)²
= 11(5996) - (209)(337) / 11(4081) - (209)²
= 65956 - 70433 / 44891 - 43681
= -4477/ 1210
= -3.7
The question asked us to find the <em>value of b</em> but we can go further to find the equation of the regression line:
a = ∑Y - b∑X / n
= 337 - (-3.7)(209)/ 11
=1110.3/11
= 100.94
the equation is:
Y = 100.94 - 3.7X
