Can someone with this vertices question.

A

Step-by-step explanation:

The translation rule for

R(- 5, - 5) → R'(0, - 13) is

(x, y) → (x + 5, y - 8)

Hence U(- 5, 1) → U'(- 5+ 5, 1 - 8) → U'(0, - 7) → A

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.
