Anna's parents maintain a checking account for anna while she is attending college. her parents make an initial deposit of $500. they make additional deposits throughout the semester of $350 each. if x represents the number of deposits her parents make, does f(x) = 350x + 500 model the situation? explain why or why not.

Yes

Step-by-step explanation:

The equation does model the situation. they are make 350 dollar donations with a base of 500. That means you need to have x with the 350 and not the 500.

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.
