Lisa is in charge of buying door prizes for the school dance. She bought 100 items made up of $2 cups and $3
bracelets that commemorate the dance. The total cost for
the items was $260. Without knowing the numbers of each
item Lisa bought, Sandra writes this system of equations to
figure it out on her own.
c+b=100
2c+3b=260
In the equations, c represents the number of cups and b
represents the number of bracelets. How many cups did
Lisa buy?

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:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
