Identify the mean and standard deviation of the graph. Choices:

mean = 23.8; standard deviation = 2.7
mean = 18.6; standard deviation = 5.2
mean = 18.6; standard deviation = 2.7
mean = 23.8; standard deviation = 5.2

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

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?
