Whats the prime factorization of 42

3,7,2

Step-by-step explanation:

42 = 21*2

42 = 3*7*2

Ta da!

Hope this helps! :)

The prime factorization is 46 = 2 times 3 times 7.

Step-by-step explanation:

So we have the number 42.

First, break 42 up into 2 and 21.

Then split those two numbers further into 3 and 7 from 21 (because they are the factors of 21).

Since you can't break it down any further, take the prime numbers from there and multiply them against each other. This is why it is called prime factorization.

Don't simplify any further and don't multiply them together. Just keep it as 46 = 2 times 3 times 7. There you go!

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.
