Which unit rate corresponds to the proportional relationship shown in the graph? drag and drop the answer into the box to match the graph with its unit rate.0.33cm/s 0.75cm/s 1.33cm/s 0.25cm/s

i think the answer is 1.33cm/s

Step-by-step explanation:

you have to use m=y2-y1/x2-x1

answer:      

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.
