Which quadratic inequality does the graph below represent?

last option

Step-by-step explanation:

The parent function of a quadratic function is :

The graph shown is the graph of parent function shifted 3 units down:

Then the second option is not correct.

Now you must choose any point of the shaded region and substitute it into the inequality 1 and 3:

( THIS IS NOT TRUE).

(TRUE)

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.
