Answer:
20
Step-by-step explanation:
Answer:
10%
Step-by-step explanation:
The change is 90-100 = -10. As a percentage of the original amount, that is ...
-10/100 × 100% = -10%
The change from 100 to 90 is a reduction of 10%.
So I am assuming we’re solving for a?
If so,
|(6/-a) - 2 | = 25
|(6/-a)| = 25 + 2
|(6/-a)| = 27
Multiply both sides of equation by -a and you get
6 = 27a
(6/27) = a
0.222 = a
So, we can check by plugging 0.222 in the original equation,
|(6/-0.222) - 2 |=25
|27-2|=25
25=25 which is correct
Answer:
33 ;
Coefficient of determination.
Step-by-step explanation:
The Numbe of independent variables is given by the degrees of freedom of regression which is 33 from the ANOVA output.
The proportion of variation in the dependent variable which is explained by a set of independent variables is given by the R² value also called the coefficient of determination. In the table above, the R² value is 0.5255139760 ; which. Means that about 0.53(53%) of variation in dependent variable is explained by the independent variables.
