X + x+2 + x+4 + x+6 +x+8 + x+10 + x+12 + x+14 + x+16 + x+18 = 1190
Now simplify
10x + 90 = 1190
10x = 1100
x = 110
Now plug in 110 for x
p=36
because 15 is 3 times 5 so just multiply the perimeter

Answer:
- (3y)(2x^2 -1x -8xy +4y)
- (3y)(x -4y)(2x -1)
Step-by-step explanation:
<u>Part A</u>: All of the coefficients have a common factor of 3. All of the variable products have a common factor of y, so the greatest common factor of all terms is 3y. The expression can be written as ...
(3y)(2x^2 -1x -8xy +4y)
__
<u>Part B</u>: The remaining factor can be factored pairwise:
3y(x(2x -1) -4y(2x -1)) = 3y(x -4y)(2x -1)

Answer:
b. 3 treatments and 21 subjectcs
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"
On this case we have 4 degrees of freedom for the numerator and 95 for the denominator.
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 or treatments. So then if we solve for k we got
The degrees of freedom for the denominator on this case is given by . And we can solve for N like this:
so we have 21 individuals in total
And the total degrees of freedom would be
On this case the correct answer would be:
