Find the midpoint of (-1, -5) and (-5, 9)

(-3,-2) is the midpoint

Step-by-step explanation:

To find the midpoint

Add the x coordinates and divide by 2 to find the x coordinate of the midpoint

(-1+-5) /2 = -6/2 = -3

Add the y coordinates and divide by 2 to find the y coordinate of the midpoint

(-5+-9) /2 = -4/2 = -2

(-3,-2) is the midpoint

Step-by-step explanation:

To solve, we have to use the midpoint formula:

Our points:

(-1, -5) (-5, 9)

Our x1 is -1, and our x2 is -5. Our y1 is -5, and our y2 is 9.

our midpoint: (-3, 2)

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.
