Answer:
.
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 (A,B,C) and on each group we have sample of size (6,5,6) respectively , 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 
On this case the correct answer would be 2 for the numerator and 14 for the denominator.
Best answer
14
The first graph. This is because the one solution is where the two lines will intersect.
In the second graph, the two lines are parallel, so there is no possible way for them to intersect. In the third graph, the two lines are on top of one another, so there’s more than one solution.
Therefore, the first graph is where there is one solution.
Answer : 50
Explanation : All angles of a triangle add up to 180
Hi there!
The correct answer is the first option - an x intercept of the graph is (0,3). If you take a look at the graph, you'll see that one line crosses the x axis at (0,3). Meaning that, this is one x axis.
Hope this helps!! :)
