Question 6 5 pts
The average amount of time to finish this quiz is 26 minutes with a standard deviation of 1.2 minutes. What is
the probability that you will finish this quiz in 25.1 minutes or less? Write your answer as a percentage with 2
decimals.

normalcdf(-1^99, 25.1, 25, 1.2) = .226627 or 22.66%

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
