Answer:
No solution (because the n's cancel out!)
Step-by-step explanation:
Let's solve your equation step-by-step.
8
2
=
6
n
+4
Multiply all terms by n and cancel:
8n
2
=6+4n
4n=4n+6(Simplify both sides of the equation)
4n−4n=4n+6−4n(Subtract 4n from both sides)
0=6
Answer:
No solutions.
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
It is any fraction except 0 of 180°.
