Make x the subject of h = 4(x + 3y) + 2

x= (h-12y-2)/4

Step-by-step explanation:

First expand the brackets so its 4x+12y+2=h

Then subtract 12y and 2 from both sides

This maxes 4x=h-12y-2

then divide by 4

so its x= (h-12y-2)/4

step-by-step explanation:

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.
