Lynbrook west, an apartment complex, has 100 two-bedroom units. the monthly profit (in dollars) realized from renting x apartments is represented by the following function. p(x) = -2x2 + 1700x - 43000 (a) what is the actual profit realized from renting the 41st unit, assuming that 40 units have already been rented?

From renting the 41st unit, you have made an actual profit of 1538 dollars.

Step-by-step explanation:

The problem states that the monthly profit (in dollars) realized from renting x apartments is represented by the following function.

This mean that when you have rented x apartments, you have made a profit of P(x) dollars.

(a) What is the actual profit realized from renting the 41st unit, assuming that 40 units have already been rented?

After you have rented 40 apartments, you have made a profit of P(40) dollars.

After you have rented 41 apartments, you have made a profit of P(41) dollars.

To find the actual profit from renting the 41st unit, you have to calculate P(41) - P(40).

So

So

From renting the 41st unit, you have made an actual profit of 1538 dollars.

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.
