Find the midpoint and length between each pair of points. (5,5) (-1,3)

PLEASE HELP!!

(2, 4)

Step-by-step explanation:

Midpoint Formula:

Simply plug in your coordinates into the formula:

x = (5 - 1)/ 2 = 4/2 = 2

y = (5 + 3)/2 = 8/2 = 4

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.
