There are twice as many people in the household, but your income has doubled. Is your new tax liability salbutamol twice as much as when you were single, more than twice as much, or less than twice as much?

twice as much as when you were single

Step-by-step explanation:

tax liability is calculated from subtracting all expenses from income. Assuming expenses also double, subtracting all expenses from income will result in tax liability twice as much as when you were single

Income initially= x

Income after increase= 2x

expenses initially= y

expenses after increase= 2x

tax liabiltiy initially= x-y

tax liabiltiy after increment= 2x-2y= 2(x-y)= 2× tax liability initially

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.
