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.
Answer:
It's been 70 days
Step-by-step explanation:
14 28 42 56 70
10 20 30 40 50 60 70

Answer:
20x+8+7=-105
20x(8+7)=-105
-15 to both sides 20x=-120
divide by 20 to both sides -120/20=-6
x=-6
Step-by-step explanation:
distributive property
addition property of equality
subtraction property of equality
division property of equality
Answer:
The solution graph is also attached.
Step-by-step explanation:
Given
as
so
solving the intervals
as
subtract 2 from both sides
also
subtract 2 from both sides
Add 3y to both sides
Divide both sides by 4
so combining the intervals
Merge overlapping intervals
Therefore,
The solution graph is also attached.
