A scale factor of 3 means that the new shape is three times the size of the original. To calculate the Scale Factor, we use the following: You can get the 'big' and 'small' from the corresponding sides on the figures. So just get your # and multiply it by 3
Reletive frequencey is (number of times desired outcomes happened)/(total times test was repeated) so 60=total times desired outcomes=20 20/60=1/3=0.3333333=33.33%=33%
I don't know the official answer but I can confirm for you that it is either C or D. I just don't remember how to determine which way the sign goes. Sorry
