1)The mean absolute deviation for brand A is .

2)The mean absolute deviation for brand B is .

3)The mean absolute deviations for the two brands similar.

Choices for the lines:

1)1.905, 2.02, 4.9, 8,

2)1.905, 2.02, 5, 5.55

3)are not, are

1 and 2

Step-by-step explanation:

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

idk
