You can use a diffrent kind of ruler for math then you could find the answer.
Answer:
The Third one.
Step-by-step explanation:
So, Turn the mixed number, 2 1/4, to an improper fraction, 9/4. Then match the answer!

Have a nice day! :)
Answer:
II. The sum of the residuals is always 0.
Step-by-step explanation:
A least squares regression line is a standard technique in regression analysis used to make the vertical distance obtained from the data points running to the regression line to become very minimal or as small as possible.
For any least-squares regression line, the sum of the residuals is always zero.
Basically, residuals are used to measure or determine whether or not the line of regression is a good fit or match for the data by subtracting the difference between them i.e the predicted y value and the actual y value, for the x value respectively.
Hence, the statement about residuals which is true for the least-squares regression line is that the sum of the residuals is always zero (0).
Answer:
6
Step-by-step explanation:
I think you mean 2x=12. Divide 2 on both sides to get x=6
Answer:
BPEMDAS (brackets, parentheses, exponents, multiplication and division, addition and subtraction)- Left to right
Notes: Two negatives make a positive. When you have an odd exponent of an negative number, you get a negactive result.
2-(-8)+(-2)³
10-8
2
Hope this makes sense! :)
