Which best describes the clusters in the data set?

A. There is no cluster in the data set.

B. There is one cluster at 13, 14, and 15.

C. There is one cluster at 12, 13, 14, and 15.

D. There are two clusters at 13 and at 15.

C) There is one cluster at 12, 13, 14, and 15.

Step-by-step explanation:

I think this because at 12, 13, 14, and 15 there are a larger amount of dots together, than with 10 and 11. Clusters form when there are large numbers of objects near each other. This is represented by 12, 13, 14, and 15.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

i will pick c put check it over to be sure
