A venue can sell 750 750 tickets per concert. For an upcoming concert, they have been selling 25 25 tickets a day. Write a linear function that represents the number of tickets remaining at a given time.

y=25x+750

Step-by-step explanation:

You have 750 fifty per day which will be your b (y=mx+b)  and you will make 25 tickets per person which will be your m.

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.
