Answer:
D. Highest increase in the multiple R2.
Step-by-step explanation:
Included variables in a multiple regression model are those variables which have the most effect on the model ; variables which have no effect on the performance of the model ar discarded. Model performance are based on the variables affect the multiple R² value of the model. The R² value is the coefficient of determination which gives the proportion of change in predicted value based on the regression line. Higher R² value means the variable has greater effect in the model performance. Therefore, variables which have the highest increase on the multiple R² value , are included.

4725 which is a whole number
Answer:
y= 2/5x+4/5
Step-by-step explanation:
identify two points on line m then find it's gradient.
using the gradient of line m find the gradient of the perpendicular line
then use points (3,2) and (x,y) to find it's equation.
The number of additional sandwiches is 15.
If we multiply 75 sandwiches by 0.2 (20%), then we get 15, which would be the number of sandwiches needed to be sold to meet the sales goal.
