Answer:
<h3>C. 10</h3>
Step-by-step explanation:
let n1 be the degree of freedom of factor A
Let n2 be the degree of freedom of factor B
If there are 5 levels of factor A, then n1 = 5
If there are 7 levels of Factor B then n2 = 7
The interaction between the degrees of freedom is expressed using the formula;
df = (n1 - 1)+(n2 - 1)
df = n1 -1 + n2- 1
df = n1+n2 -2
Substitute n1 and n2 and get df
df = 5+7-2
df = 12-2
df = 10
Hence the interaction degree of freedom is 10
(x^15)(x^-3) = x^(15 + (-3)) = x^12
n = 12
Answer:
The slope is 1/2

I did rise over run
0.4 and 0.40 are equal. That zero on the hundredths place does not matter.
