How many solutions does a system of equations have that are lines that are parallel?

To answer this question, you have to ask yourself, "What specifically is a solution to a system of equations?"

The answer to this question is: A solution is where the two lines intersect each other.

Now, you have to think, "Where do these two lines intersect each other?"

Well, one big factor is knowing that both of these lines are parallel to each other. That means they run alongside each other and never cross over.

If you put piece by piece together with this information, you can deduce that two parallel linear lines will never cross over each other and thus, have no solutions to them.

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.
