Ann's and Deb's astronomy classes are going on a field trip to see the night sky. Ann's class has 9 telescopes for 21 students. Deb's class has 12 telescopes for 28 students. Which class has the greater ratio of telescopes to students?

Answer: Neither, the two classes have the same amount of telescopes.

Step-by-step explanation:

ANN = 9 telescopes / 21 students

DEB = 12 telescopes / 28 students

Times Ann's ratio by 1/3 (basically dividing by 3)

9(1/3) / 21(1/3 = 3/7

Times Deb's ratio by 1/4 (diving by 4)

12(1/4) / 28(1/4) = 3/7

Since they are the same, neither class has more telescopes. Again, hope this is right and if not sorry.

please help due today

Phil and his family want to do something fun and memorable on Leap Day. They each come up with an activity: attend a trapeze class, go fishing, go on a hike, or visit a theme park. They settle on picking the letters L, E, A, and P from a bowl, replacing them after each pick, to make the decision. They repeat this experiment 40 times to verify their model and record the results in this table.
Below is the chart
Activity Letter Times Picked
trapeze class L
10
fishing E
11
hiking A
9
theme park P
10


Based on the results in the table, is this model a fair representation for choosing an activity?
A.
No, it is an unfair model because the outcomes have different frequencies.
B.
No, it is an unfair model because the relative frequency of the letter E is the highest.
C.
Yes, it is a fair model because the relative frequencies of the letters L and P are equal.
D.
Yes, it is a fair model because the relative frequencies of all the outcomes are similar.
