Which expression shows the sum of the polynomials with like terms grouped together? (8x+37 - 822)+(4y - 52)
o [8x+4y+(-82)] +37+(+52)
Bx+4y+ (32+ (-822) +(+52)
[8x+(-822)] +4y+[32+(-57)]
8x+4y+ (-822) + [32+(-52)]

its 69.420

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.
