Ajar contained 18 red marbles, 14 green marbles, and 20 blue marbles. a marble was selected at random, the color was recorded, and the marble was placed back in the jar. the table shows the results after 60 trials. what was the relative frequency of selecting a blue marble? enter your answer in the box to the nearest percent.

This is very late but but for helping other people in the future, the answer is 33. I took the test and it's correct. Here is a screenshot:

the co-ordinates of the transformed rectangle are:

d. (0, 0), (0, 3), (-3, 3), (-3, 0)

step-by-step explanation:

from the columns of the given matrix, the co-ordinates of the rectangle before transformation are:

(0, 0), (0, 3), (3, 3), (3, 0)

r =

transformed matrix can be obtained by multiplying the given matrix by r:

columns of the transformed matrix are:

0   0   -3   -3

0   3     3     0

from the columns of the resulted matrix, we can see that the vertices of the transformed triangle are:

(0, 0), (0, 3), (-3, 3), (-3, 0)
