36 colored
faction 36/60 = 18/30 = 6/10 = 3/5
faction not equivalent to is 8/20
answer is C. 8/20
11)
answer is D. 18.21
cause 18.21 > 17.06 and 18.21 < 18.307
Answer:
C
Step-by-step explanation:
When completing the square, we essentially want to create a perfect square trinomial by adding a constant.
If we have the following expression:

And we want to complete the square, we will need to divide the b-coefficient by half and then square it.
Thus, the added term should be:

In the given equation, we have:

The b term here is 8. Therefore:

The value we would add would be 16.
The answer is C.
Further notes:
To complete the square, add 16 like mentioned earlier. However, we also need to subtract 16 to balance things out:

The expression inside the parentheses is now a perfect square trinomial. Factor it:

And we are done!
Total money = 150 + 95 + 210 + 45 + 55 + 165 = $720
Total months is 6
Mean = 720 / 6 = $120
