Sophie surveyed kids in her class and found two out of every five of them had seen an animated movie in the past month. If there are 30 kids that Sophie surveyed, how many saw an animated movie in the past month? Use the tape diagram to justify.

12

Step-by-step explanation:

30÷5

=6

therefore,

2×6

=12

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
