Answer:
a.the goodness of fit for the estimated multiple regression equation increases.
Step-by-step explanation:
As the value of the multiple coefficient of determination increases,
a. the goodness of fit for the estimated multiple regression equation increases.
As we know that the coefficient of determination measures the variability of response variable with the help of regressor. As we know that if the value of the coefficient of determination increases strength of fit also increases.
Answer:
(1/3)⁷
Step-by-step explanation:
negative exponents work like this:
x⁻²=(1/x)²
Apply this theory to this equation:
3⁻⁷=
(1/3)⁷

3. x = 14 degrees
4. x = 17.5 degrees
Step-by-step explanation:
SO, The first question:
6x - 21 = 105
6x = 105 -21
6x = 84
x = 14
SO, The second question:
55 + 85 = 8x
140 = 8x
17.5 = x
