Answer:
(2, 12)
Step-by-step explanation:
Analysis of variance (ANOVA) "is used to analyze the differences among group means in a sample".
The sum of squares "is the sum of the square of variation, where variation is defined as the spread between each individual value and the grand mean"
If we assume that we have groups and on each group from we have individuals on each group we can define the following formulas of variation:
And we have this property
The degrees of freedom for the numerator on this case is given by where k =3 represent the number of groups.
The degrees of freedom for the denominator on this case is given by .
And the total degrees of freedom would be
And the correct answer would be 2 degrees of freedom for the numerator and 12 for the denominator

Answer:
y=+9
Step-by-step explanation:
y=mx+b
m is the slope and b is the y intercept, replace m with 0 and replace b with 9.

1,200*.1=120
1200-120= 1080
1080

199.95*.3=59.99 (rounded)
199.95-59.99=140
140
