7. Braydon wants a triple-scoop ice cream cone. In his freezer, he has strawberry,
maple walnut, and blueberry ripple ice
cream.
a) Use a tree diagram to determine how
many possible combinations Braydon
can choose.

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.

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

2x^2+5x+17

your welcome. : )

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves
