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.
Just ignore that bot. The actual answer would be y = 1/4X - 2!
Answer:
Step-by-step explanation:
sin^2x=1/2
so sinx=1/V2=V2/2
x=pi/4
C^2=a^2+b^2
√117^2=6^2+x^2
117=36+x^2
81=x^2
9=x
hope this helps :))
