The difference between two number is 6, and their product is 27. Find d number​

3, 9

Step-by-step explanation:

The only factors of 27 are 1, 3, 9, and 27, so we can look at the numbers and see which ones have a difference of 6. 3 and 9 have a difference of 6, so the numbers are 3 and 9. I hope I helped!

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.
