Name the ordered pair that corresponds to an angle of a pi radians

3π (540°) and 5π(900°)

Step-by-step explanation:

π radian = 180° degree

in the trigonimitrical cercle each point is taken by many values

so π position is also -π position

to move from π to -π you should move 360° (wich is 2π) backwards

π-2π = π

so  -π = π +2π

you can get as much as you can of values similar to π using the formula :

π + 2*k*π where k is a relative number

π+ 2*1*π = 3π

π+2*2*π = 5π

3π is 540°

5π is 900°

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.

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
