BRAINLIEST and PLEASE show your work Solve for y using the formula y = x^2(2+4); when x = 4

y=96

Step-by-step explanation:

y=4^2(2+4)

y=16(2+4)

y=16(6)

y=96

96

Step-by-step explanation:

Important information:

x^2(2+4)

x=4

Explanation/Solution:

x^2(2+4)

4^2(2+4)

16 (2+4)

16 · 6 =

96

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.
