Hey umm can someone help me, it's urgent,,, thanks. You have $20 in your piggy bank. You spend $2 every day on snacks. What relationship is there between the amount of money in your bank and the number of days you buy snacks?
Is it positive or negative?

The relationship is m=20-2d. The relationship is negative.

Step-by-step explanation:

The relationship is m=20-2d (m is the amount of money in your bank and d is days). This is because the amount of money you have equals the 20 dollars you originally had minus 2xd or 2d (this is because you spend 2 dollars each day) The relationship is negative because you are subtracting/taking out money. Hope this helps!

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.
