A quadratic regression is the process of finding the equation of the parabola that best fits a set of data. As a result, we get an equation of the form: y = a x 2 + b x + c where a ≠ 0 . The best way to find this equation manually is by using the least squares method.
Answer: PQT and TUV
Step-by-step explanation:
Answer:
-1x - 3 or -x - 3
Step-by-step explanation:
1/5 (5x - 15) - 2x =
1x - 3 - 2x =
1x - 2x - 3 =
-1x - 3
I think the answer would be D.
Explanation:
I think it’s D because it asks which is “skewed right”, and most of the data is on the right side of D
Thats easy
