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

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

57/70

=0.81

Randy chooses to survey every 5th student in the cafeteria. He surveys a total of 140 students and finds that 84 support buying
umka21 [38]

Answer: He can predict that 420 students will be in support of the purchase.

Step-by-step explanation:

Since Randy surveyed one student out of every 5 he came across in the cafeteria, it means that if he came across five people, he will survey one, if he came across ten students, he will survey 2 and so on.

If then he surveyed a total of 140 students, then we can actually multiply the number by 5 to know the exact number of students he possibly came across in the cafeteria:

= 140 × 5

= Total of 700 students

If 84 out of the surveyed students supported the purchase, we can find what that figure represents in the total number of students in the cafeteria:

84/140 = x/700

We cross multiply

140 × X = 84 × 700

140X = 58,800

X = 58,800/140

X = 420 students

Therefore, he can predict that 420 students out of a total of 700 students in the cafeteria will be in support of the purchase of the P.E equipment
