Answer:
B
Step-by-step explanation:
We know that 3² = 9, so for g(x) to pass through (3,3), we need to multiply x² by 1/3, giving option B.
subtract 14 from 22 to isolate the variable
Answer: b
Explanation:
The line of best fit to a scattergram is obtained in linear regression analysis by minimizing the sum of the squared errors.
For example, in the diagram shown below, there are n data points in the scattergram.
The error for the i-th data point is

.
The coefficients (a and b) for the line of best fit are determined using calculus, to minimize

.
AFB, the sides are similar
