48 The graph of g(x) = x2 was transformed to create the graph of h(x) = -
-0)

describes the transformation from the graph of g to the graph of h?
F A reflection over the x-axis and a horizontal stretch

H A reflection over the x-axis and a vertical stretch
A reflection over the y-axis and a vertical stretch

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.

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
