Erika is saving up money to buy a car when she turns 16. Right now, she has $450 in her savings account . If she needs at least $3,000 to purchase a car, what is the least amount of money she will need to save each year over the next three years in order to be able to save at least $3.000 ?

850$ each year.

Step-by-step explanation: 3000-450=2550. Then divide 2550 with 3 because 3 is how much years left then get 850.

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.
