A1(8,0)

B1(12,6)

C1(6,8)

Step-by-step explanation:

If its dilated by a scale factor of 1/2, that means for each x and y-coordinate you divide by 2 to get the new scale factor

Originally A(16,0) so now it would be A1(8,0)

Originally B(24, 12) so now it would be B1(12,6)

Originally C(12, 16) so now it would be C1(6,8)

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.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
