Answer:
A
Step-by-step explanation:
Taking the square root of both sides.
[891/33=27] ratio of the two prism: hencesurface area of smaller prism is[153/27]=5.67cm
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

.
