Which statement describes values of x and y such that could be an irrational number? A. The value of x is zero, and the value of y is an integer less than zero.

B. The value of x Is the square root of an integer, and the value of y is an Integer
greater than zero.

C. The value of x Is an Integer less than zero, and the value of y is an Integer greater than zero.

D. The value of x Is a square root that can be simplified to an Integer, and the value of y is an
Integer less than zero.

The answer is B

It's not A, C, or D, because they all are stated as integers, which cannot be irrational

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.
