Use the figure below to answer the question.
describe a sequence of transformations that maps
∆abc to a'b'c'

Translation and then reflection

Step-by-step explanation:

First traslation of triangle ABC of 10 units to the right (+10,0)

A: (-5, 4) -> (+10,0) = A'': (5, 4)

B: (-6, 2) -> (+10,0) = B'': (4, 2)

C: (-4, 2) -> (+10,0) = C'': (6, 2)

Second a reflection across the x-axys.

A'': (5, 4) -> A': (5, -4)

B'': (4, 2) -> B': (4, -2)

C'': (6, 2) -> C': (6, -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.
