Drag the tiles to the boxes to form correct pairs. polygon abcd is defined by the points a(-4, 2), b(-2, 4), c(1, 3), and d(2, 2). match the coordinates of the points of the transformed polygons to their correct values.

D'(-2, 2); C''(3, -1); A'''(4, -2); and B''(4, 2)

Step-by-step explanation:

For D', we rotate the point (2, 2) 90° counterclockwise. This maps every point (x, y)→(-y, x); it takes (2, 2)→(-2, 2).

For C'', we rotate the point (1, 3) 90° clockwise.  This maps every point (x, y)→(y, -x); it takes (1, 3)→(3, -1).

For A''', we rotate the point (-4, 2) 180° clockwise.  This maps every point (x, y)→(-x, -y); it takes (-4, 2)→(4, -2).

For B'', we rotate the point (-2, 4) 270° counterclockwise.  This is the same as rotating the point 90° clockwise.  This maps every point (x, y)→(y, -x); it takes (-2, 4)→(4, 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.
