Find the mean (average) of each set of numbers. Round your answer to the nearest tenth 17 , 17 , 11 , 10 , 1 , 20 , 17 , 17

13.8

Step-by-step explanation:

Mean means adding all the numbers divided by the total numbers

So we have,

17+17+11+10+1+20+17+17 =110

Total numbers = 8

Mean = 110/8

=13.75

=13.8 (to the nearest tenth)

y=1/4x-4

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
