X^2 goes into - 3x^2 how many times?

3 time

Step-by-step explanation:

write out the problem

-3x^2 / x^2

-3x^2 can be written as

-3 * x^2

so then the problem is

-3 * x^2 / x^2

= -3

the abs. value of -3 is 3

so it goes into it 3 times

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.
