50 points and branliest to whoever figues this out.

consider that δxyz is reflected across the y-axis and translated 2 units down.

choose all true statements about the transformation.

x'y' ≅ xy
∠z ≅ ∠z'
δxyz is not congruent to δx'y'z'.
reflecting and translating the triangle change its shape and size.

answer:

the third one

.

step-by-step explanation:

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.
