Which function is nonlinear? a.) 9y + 3 = 0 b.) y - 4x = 1 c.) y = 2 + 6x^4 d.)x - 2y = 7 e.) x^y + 1 = 2 h !

C.) Y = 2 + 6X^4   not linear

E.) X^Y + 1 = 2  not linear

Step-by-step explanation:

linear functions are in terms on x and y, no exponentials

A.) 9Y + 3 = 0      linear

B.) Y - 4X = 1   linear

C.) Y = 2 + 6X^4   not linear

D.)X - 2Y = 7   linear

E.) X^Y + 1 = 2  not linear

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.
