Sophia made the following two-way table categorizing the US senators in 2015 by their political party and whether or not it was their first term in the senate. Find the probability that the senator was in the Democratic party, given that the senator was returning to office. P (Democrat | returning) =

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
