Buying one movie ticket online costs 16.50, two tickets cost 30.50

Recursive Formula: =an-1+14; a1=16.50

Explicit Formula: an=2.5+14n

Step-by-step explanation:

The common difference is 14, as you would add 14 to 16.50 and get 30.50 for two tickets. However; the tickets are not the same amount of money each, since 16.50 is not a multiple of 14, (neither are 30.50, 44.50, and 58.50.)

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!

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.
