Answer:

Relative frequency, by row, of students who like both tacos and pizza is:

0.81

Step-by-step explanation:

                                  Like Tacos Do Not Like Tacos      Total

Like Pizza                    57                 13                       70

Do Not Like Pizza            12                  15                       27

Total                            69          28                       97

The relative frequency by row is calculated as the ratio of the frequency of the required field to the total frequency of that row

H e l p m e <br> will give brainliest answer. I'm very not smart sos
USPshnik [31]
Since this is a test, I'm not going to give you the answer...

but, remember, the formula to find area for a square is base multiplied by the height.

For a triangle, it would be base multiplied by the height, then divided by 2.

Remember to add up the shapes' areas when necessary!
