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
Answer:
| x + 4 | = -1 No solution
Step-by-step explanation:
3 | x + 4 | + 12 = 9
Subtract 12 from both sides: 3 | x + 4 | = -3
Divide both sides by 3: | x + 4 | = -1
Absolute value cannot be negative, so there is no solution.
Pablo has $4,200 to invest for college. Pablo's goal is to have $5,000 after 4 years. Question: Is this possible if he invests with a rate of return of 6%?We'll we are not sure with the answer unless we solve it. So let's start solving.=> 6% = 6% / 100% = 0.06Now, we have the value of 6% that will be multiplied with the amount to identify his annual interest rate:=> $4,200 * 0.06 = 252 dollars is his annual interest rateLet's multiply this for 4 years=> 252 dollars * 4 = 1008 dollarsThen, let's sum up:<span>=> $4,200 + 1008 dollars = 5 208 dollars.</span>
