The value of y is directly proportional to the value of x. If x = 18, then y = 4. What is the value of y when x = 27?

y = 6 when x equals 27  Trust me,

Step-by-step explanation:

  Because for the first one you multiply x by 4.5 to get y, that is the proportion, we do the same thing for 27, so just to check 6*4.5 is 27 (you wont)

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.
