3, 13, 14, 9, 7, 3, 3, 13
Find the median travel time for that group of students.

8

Step-by-step explanation:

First put the numbers least to greatest.

3, 3, 3, 7, 9, 13, 13, 14

Now cross the numbers left to right until you reach the middle.

3, 3, 3, 7, 9, 13, 13, 14

Since there are 2 numbers in the middle, you have to combine them and divide by 2.

9+7=16

16/2=8

Final answer

8

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
