What are the relative frequencies to the nearest hundredth of the columns of the two-way table?

                                     A                               B

Group 1.                     0.33                           0.81

Group 2.                    0.67                           0.19

Step-by-step explanation:

To answer this question we must add the frequencies of A and B

This is:

Group 1: f(A) = 24

Group 2: f(A) = 48

Total (A) = 24 + 48 = 72

Then

Group 1: f(B) = 44

Group 2: f(B) = 10

Total (B) = 44 +10 = 54

Now we divide each value of f(A) between the total of (A) and each value of f(B) between the total of (B)

                      A               B

Group 1.         

Group 2.         

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
