Eli has 7 games on his phone . his sister has 6 more than him which ratio compares the number of games on Eli's phone to the number of games on his sisters phone,

7:13

Step-by-step explanation:

Since Eli has 7 games and his sister has 6 more than him, first you would add 7 to 6 and would get 13.

7 + 6 = 13

After you add, since the question is asking which ratio compares the number of games on Eli's phone compared to the number of games on his sister's phone, the number of Eli's games would go first, and then his sister's number of games would be the second number in the ratio, leaving you with 7:13.

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.
