Which equation defines p as a function of t?

(A) p = 3 t +2

Explanation:

The equation p = 3 t + 2 defines p as a function of t.

Here, p is the dependent variable whose value is determined by the value of t.

t is the independent variable.

In equation t = 3 p + 2, t is a function of p.

In equation p = 0 t + 2, p is independent of t and thus is not a function of t.

In equation t = 0 p + 2, t is independent of p and thus is not a function of p.

Therefore, p = 3 t + 2 shows p as a function of t

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.
