Pls help i really need it Which best describes the clusters in the data set?

Number of Fish in Each Tank at the Pet Store
A dot plot going from 10 to 15. 10 has 6 dots, 11 has 8 dots, 12 has 0 dots, 13 has 4 dots, 14 has 2 dots, 15 has 3 dots.
There is only one cluster, at 10 and 11.
There is only one cluster, at 13, 14, and 15.
There are two clusters at 10 and at 11.
There are two clusters, at 10 and 11, and at 13, 14, and 15.

it would be .c

Step-by-step explanation:

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

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
