:a sub shop sold sandwiches that were 1/2 a foot long. if you were to cut the sandwich into 8 equal pieces, what fraction of a foot would each piece be?

The size of each piece (fraction of foot) = 1/16 foot

Step-by-step explanation:

Total size = 1/2 feet

total pieces = 8

To calculate the equally sized pieces, we divide the total size by the number of pieces

=>

=>

=> feet

Therefore the size of each piece (fraction of foot) = 1/16 foot

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.
