Need ! find the equation of the hyperbola centered at the origin that satisfies the given conditions: vertex: (0, square root of 12), passing through (2, square root of 3, 6) a. y^2/36 - x^2/12 =1 b. y^2/12 -x^2/36 =1 c. y^2/6 - x^2/12 =1 d. y^2/12 - x^2/6 =1

yes

yes yes yes

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.
