Which of the following situations could be represented by the equation y = 3x + 5?

A. A bricklayer lays 5 bricks in 3 minutes. What is the total number of bricks he can lay in x minutes?

B. An express package costs $5 plus $3 per pound to ship. What is the total cost for x pounds?

C. A jogger is 3 miles from home, jogging toward home at 5 miles per hour. What is the total number of minutes it will take her to get home?

D. A math teacher gave some problems worth 5 points and a bonus problem worth 3 points. What was the total value of the problems?

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.
