Lauren rides her bike 36 miles in 4 hours. How many feet is Lauren traveling each minute?

786 feet per min

Step-by-step explanation:

60 (mins in an hour) x 4= 240 mins

there are 5240 feet in a mile

5240 (feet in a mile) x 36= 188640

188640 divided by 240= 768

were is the equation

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.
