A) Roll a die letting 1 represent Ira making an A and 2-6 represent Ira not making an A. Roll the die four times.
B) Roll a die letting 1 represent Ira making an A and 2-6 represent Ira not making an A. Roll the die five times.
C) Using a table of random digits select a digit between 0 and 9. Let 0-7 represent Ira making an A and 8-9 represent Ira not making an A. Select four digits.

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
