Asap 25 pts + brainliest to right/best answer

40

Step-by-step explanation:

1. (h°g)(-3) = h(g(-3))

2.  -6 into h(x).

h(-6) = (-6)2 + 4

       = -12+4

       =-8

3. (for the exponent of 2)

h(-6) = (-6)2 + 4  

        = 36 + 4  

        = 40

A.

Step-by-step explanation:

This is my second account so I can mark you brianliest.

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.

a: 1/6, j: 1/4
