On a 40 minute bike ride the bicycle wheels revolve 2400 times. what is the constant of proportionality? (a.) 0.016 revolutions per minute; the cons of proportionality is 0.016.(b.) 20 revolutions per minute; the constant of proportionality is 20.(c.) 40 revolutions per minute; the constant of proportionality is 40.(d.) 60 revolutions per minute; the constant of proportionality is 60.

60 rev/min (Answer D)

Step-by-step explanation:

Calculate it!  

2400 revolutions

= 60 rev/min

  40 minutes

just find the gcf and solve the gcf's until you get each answer i have a really good feeling somethings missing xd (like the dimensions of the fence) *cough *cough *hint *hint

step-by-step explanation:

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.
