Grace works from 10 to 20 hours per week while attending college. she earns $9.00 per hour. her roommate frances also has a job. her pay for t hours each week is given by the function f(t)= 10t, where 5t ≤ t ≤ 15.

a. find the domain and range of each function.

b. compare their hourly wages and the amount they earn per week.

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.
