Which describes the correlation shown in the scatterplot? On a graph, points are grouped together and decrease. There is a positive correlation in the data set. There is a negative correlation in the data set. There is no correlation in the data set. More points are needed to determine the correlation

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

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
