question 121

Multiple Choice

Factor completely. If the polynomial cannot be factored, write ʺprime.ʺ
- $5 x ^ { 2 } + 5 x y - 60 y ^ { 2 }$

• A) \(( 5 x + 15 y ) ( x - 4 y )\)
• B) \(5 ( x + 3 y ) ( x - 4 y )\)
• C) \(( x - 3 y ) ( 5 x + 20 y )\)
• D) \(5 ( x - 3 y ) ( x + 4 y )\)

Definitions:

F-Test

A statistical test used to compare the variances of two populations to see if they are significantly different.

Multicollinearity

A statistical phenomenon in which two or more predictor variables in a multiple regression model are highly correlated, potentially distorting the model's coefficients.

Biased Estimates

Estimates that are systematically different from the population parameters being estimated, due to errors in data collection, analysis, or selection.

Slope Coefficients

In linear regression, the slope coefficient measures the rate of change in the dependent variable for a one-unit change in the independent variable.
