Find the rate of money collected per sweatshirt sold.

+20

Step-by-step explanation:

I added 20 dollars per sweatshirt. I wasn't sure if you wanted me to fill in the blanks or not, but :

5 sweat shirts is 100

8 is 160

and the 180 one is 9 sweatshirts

while the last one is 240.

The pattern makes sense in the context!!

I hope this makes sense!!

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.
