IF ANYONE GETS THIS ILL GIVE A BRAINLIST JUST PLS EXPLAIN IT

-5/2

Step-by-step explanation:

n +1/2 = -3/4

Cross Multiply

4n + 4 = -6

Then subtract 4 and put it on the other side

4n = -10

Now divide by 4 on both sides

n = -10/4

And finally, simplify

-10/4 = -5/2

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

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.
