Abyte is the amount of computer memory needed to store a letter of the alphabet. in the 1980s, a computer had approximately 8.0 times 10 to the power of 3 bytes of memory. today's computers have approximately 4 times 10 to the power of 9 bytes of memory. how many times more memory do today's computers have than computers in the 1980s? write your answer using scientific notation

Step-by-step explanation:

wow

the last choice

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.
