HELP PLEASE What is the midpoint of the vertical line segment graphed below? (2,4) (2,-9)

(2, -5/2)

Step-by-step explanation:

We can easily find the midpoint of this line using the midpoint formula. Although we can just find it by looking at the graph, let's try finding the midpoint using the formula to make sure we are correct.

answer: 43/157

this is the answer and if you try to prove me wrong your a meanie

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.
