40 points plz urgent what are the relative frequencies

Hi,
To calculate this use this formula:

Relative Frequency = subgroup of data / total of the data

total of A = 72
Total of B = 54

now
Group1-A= 24/72 = 0.33
Group1-B= 44/54 = 0.81
Group2-A=48/72= 0.666(but rounding to nearest hundrest would be 0.67) = 0.67
Group2-B=10/54= 0.19 (After rounding)

Here, We know,
Relative Frequency = Magnitude of species / Total Value

Value of A = 72 & Value of B = 54

Then, 
Section (1A) = 24/72 = 0.33
Section (1B) = 44/54 = 0.81
Section (2A) =48/72= 0.67
Section (2B) =10/54= 0.19

[ Just fill the boxes with those values, and don't mismatch columns & raws ]

Hope this helps!

This is what i found “answer: a rigid transformation preserves both the side lengths and the angle measures of a polygon. step-by-step explanation: rigid transformations are the transformations which does not affect the size and the shape of figure .” i hope this you for what your looking for. can you plz mark me brainliest?
