Which statement is true about the number −5 ? the number −5 is not a rational number because it cannot be written as a ratio of integers. the number −5 is a rational number because it can be written as the fraction −51 . the number −5 is a rational number because it can be written as the fraction −50 . the number −5 is not rational number because it is a negative integer. a number line ranging from negative fourteen to positive six, with increments of one unit.

the answer would be D. –5 is an integer, but not a whole number :3

step-by-step explanation:

just plug in each number for x and see which ones work and don't

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.
