The slope of BC is
(4-2)/(-3-2) = -2/5

The slope of AD is
(-2- -4)/(-2-3) = -2/5

The slope of CD is
(2- -4)/(2-3) = -6

The slope of BA is
(4- -2)/(-3- -2) = -6

BC ∥ AD and CD ∥ BA because their slopes are equal. Therefore, ABCD is a parallelogram because both pairs of opposite sides are parallel.

If the opposite sides of any quadrilateral are parallel to each other, then the quadrilateral is entitled to a parallelogram. Thus, ABCD is a parallelogram.

The question is asked to prove the quadrilateral ABCD a parallelogram.

Now, If the opposite sides of any quadrilateral are parallel to each other, then the quadrilateral is entitled to a parallelogram. If the slope of lines is congruent to each other then the lines are parallel.

The formula for finding the slope of a line from the given coordinates (x_1,y_1) and (x_2, y_2) is mentioned below:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

Therefore,

The slope of AB is -6.The slope of BC is -2/5.The slope of CD is -6.The slope of AD is -2/5.

Now, the slope of AB is congruent to the slope of CD, and the slope of BC is congruent to the slope of AD.

Hence,

$AB \parallel CD\\BC \parallel AD$

Thus, ABCD is a parallelogram.

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.
