Apainter earns $15 per hour what is the minimum number of hours he must work to earn at least $200? write an inequality to represent this situation and to represent this situation and solve

15x>200.  The minimum number of hours he must work to earn at least $200 is 14 hours.  Working 14 hours will allow him to receive $210.  This is the minimum number of hours he can work because if he works 13 hours instead, he will only make $195, which is less than 200.  15x>200 (15x is equal to or greater than 200) x=14.

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.
