Aglass vase weighs 0.61 lb. how much does a similarly shaped vase made of the same glass weigh if each dimension is 2 times as large? explain. a. 2.44 lb; the vase dimensions are 2 times as large, so the weight is 4 times as much because 2sq = 4. b. 1.22 lb; the vase dimensions are 2 times as large, so double the weight. c. 9.76 lb; the vase dimensions are 2 times as large, so the weight is 16 times as much because 2sq4 = 16. d. 4.88 lb; the vase dimensions are 2 times as large, so the weight is 8 times as much because 2sq3 = 8.

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.
