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
Answer:
19 < x < 31
Step-by-step explanation:
The range for the third side is
25-6 < x < 25+6
19 < x < 31
Take the other two sides and subtract and take the other two sides and add
Subtract 30, then factor the equation.
... x² = 30
... x² - 30 = 0
... (x -√30)(x +√30) = 0
By the zero product rule, the solutions are values of x that make a factor be zero.
... x - √30 = 0 . . . . the first factor is zero
... x = √30
... x + √30 = 0 . . . . the second factor is zero
... x = -√30
The solutions are . . .
... x = ±√30 . . . . . matches your 3rd choice
Answer:
or 8.944
Step-by-step explanation:
Simplify
Square root both sides to get x by itself
or 8.944
The answer is 5:) you first have to cross multiply then divide both sides from x
