P and Q are two geometrically similar solid shapes the total surface area of shape P is 540cm
the total surface area of shape Q is 2160cm
the volume of shape P is 2700cm
calculate the volume of shape Q

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.

step-by-step explanation:

sry but any answer choices

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
