Whicg graph represents the solution set for the inequality 1/2x <18
2 answers:
To draw the region that represents the solution of the inequality you have to:
1. draw dashed vertical line (dashed because of sign of inequality is <, doesn't include notion equal to);
2. shade the region that determines all points on the coordinate plane that have x-coordinate less than 36.
The attached diagram represents the solution set for the given inequality.

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
