Show all steps: f(x)=3x-7 and g(x) = -2x-6. find (f o g) (4)

(f o g) = - 6x - 25

Step-by-step explanation:

(f o g)= f(g(x)) = 3(-2x-6) -7 = -6x-18-7 = - 6x - 25

Instead of x in f(x) we put g(x) value.

step-by-step explanation:

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.
