Answer:
3 1/5
Step-by-step explanation:
Pretty simple, just take away what u have top from bottem
Common denominator would be 15 and the fractions would turn into 6/15 and 10/15
The brown line is 180 -60 = 120 degrees
120/360 = 0.333
24 * 0.333 = 8
answer is 8PI, the 2nd choice
Answer: -1
Step-by-step explanation:
3( x +7 ) =18
8Use distributive property
3x + 21 = 18
Substract 21 from both sides
3x = -3
Divide 3 by both sides
x = -1
Another way to solve:
3( x +7 ) =18
Divide 3 by both sides
x + 7 = 6
Substract 7 by both sides
x = -1
The coefficient of determination is the ratio of the sum of squares regression and the ssy
The sum of squares regression is 27
<h3>How to determine the sum of squares?</h3>
The given parameters are:
Coefficient of determination, R^2 = 0.12
SSy = 225
The coefficient of determination is calculated as:
R^2 = SSR/SSY
So, we have:
0.12 = SSR/225
Make SSR the subject
SSR = 0.12 * 225
Evaluate the product
SSR = 27
Hece, the sum of squares regression is 27
