Gabrielle earned $18 an hour and get a 12% rate. with her raise how much will she earn after working 40hrs

Step-by-step explanation:

As, in 1 hour she gets =$18

And 12% rate

Now we will see how much she gets in 1 hour with raise= 12% of 18 = 2.16

So 2.16 + 18 = $20.16

So in 1 hour he gets = $20.16

Now in 40 hours = $20.16 x 40

= $806.4

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.
