I believe it’s the 3rd option but I’m not completely confident
Step-by-step explanation:
who am I kidding I’m never confident lol
2(x+1)+3x=37
simplifythe left side:
2x +2 +3x = 37
Combine like terms:
5x +2 = 37
Subtract 2 from both sides:
5x = 35
Divide both sides by 5:
x = 7
Answer:
True. See explanation below

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 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 we can find the F statistic

Which degree maps the triangle onto itself
The degrees that can map a point, line, or shape onto itself are:

i.e. multiples of 360
Looking at the given options
is correct because it can be found in the listed multiples
In other words, it will map point
to point
