a. Write a system of inequalities that shows the possible number of students and adults that can attend in order to make at least $ 2100 with the limit of 600 people. b. Sketch (AND LABEL!) a graph of the inequalities in the coordinate plane on real graph paper. c. List three solutions from your graph and show that these solutions work. Give your answers in real life, not as an ordered pair. d. Is the point (500, 100) a solution to the system?​

step-by-step explanation:

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.
