To make a profit, a company’s revenue must be greater than its operating costs. the company’s revenue is modeled by the expression 7.5x – 100, where x represents the number of items sold. the company’s operation costs are modeled by the expression 79.86 + 5.8x. how many items does the company need to sell to make a profit?

1. 7.5x - 100 > 79.86 + 5.8x (Option A)

2. x > 105.8 (Option D)

3. 106 (Option D)

Step-by-step explanation:

Just completed the assignment and got 100%. Hope this helps :)

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.
