AAA batteries are advertised to have a life of about 9 hours of use. With certain level of confidence. It is advertised that the life is between 8 to 10 hours. If 9 hours is the point estimates then the margin of error is.

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

25/6 hope it : )
