The answer is 64+8y+y².

In a perfect square trinomial, you can divide the value of b by 2 and square it, and it will equal the value of c. This works in every other trinomial listed except this one:

8/2 = 4; 4²=16≠64.

Step 1: Find the mean. mean = StartFraction 32 + 4 + 12 + 40 + 20 + 24 Over 6 EndFraction = 22 Step 2: Find each absolute deviat

DedPeter [7]

Answer:

(C)Stefano should have divided by 6 when finding the mean absolute deviation.

Step-by-step explanation:

Step 1: Find the mean.

$Mean = \dfrac{32 + 4 + 12 + 40 + 20 + 24}{6}=22$

Step 2: Find each absolute deviation.

10, 18, 10, 18, 2, 2

Step 3: Find the mean absolute deviation.

$M A D = \dfrac{10 + 18 + 10 + 18 + 2 + 2}{4} =\dfrac{60}{4}=15$

However, there are 6 values in the data. Stefano should have divided by 6 when finding the mean absolute deviation.

The correct mean absolute deviation is therefore:

$M A D = \dfrac{10 + 18 + 10 + 18 + 2 + 2}{6} =\dfrac{60}{6}=10$
