Hyun woo is riding a ferris wheel. h t h(t) models his height (in m m) above the ground, t t seconds after the ride starts. here, t t is entered in radians. h t 1 0 cos 2 ? 1 5 0 t 1 0 h(t)=? 10cos( 150 2? ? t)+10 when does hyun woo first reach a height of 1 6 m 16 m? round your final answer to the nearest whole second.

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.

191 students play sports and ninety-seven 10th graders were surveyed.
