A plumber charges $70.00 for the first hour and $50.00 for each additional hour spent on a job. The plumber does not adjust the cost for partial hours, so a partial hour is charged as a full hour. The service charge in dollars, S, as a function of time in hours, h, is what type of function? A. exponential function B. step function C. linear function D. periodic function

linear function

Step-by-step explanation:

I believe it's a linear function due to the fact you start with $70 and for every hour after, x, is $50 so there is no change in increase. So it is linear. 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.
