evaluate the piecewise function at the given value of the independent variable.

3x + 1 if x < -1
f(x) =
-2x -5 if x > _ -1

determine f(2)

-9
-8
-3
1

Determine f(2).

Because 2>-1 we input 2 into every instance of x in the second function.

f(2)=-2(2)-5=-4-5=-9

-9

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: r there any options?
