Based on last week's sales, a store manager concluded that by pricing the store's package of 12 12
donuts at $8

, the store will sell about 80

packages per day. Raising the price to $8.50

8

50
per package of 12
12
donuts will cause sales to fall to about 76
76
packages per day. If a linear model based on this data is used to predict the daily sales of y
y
packages of donuts when the price per package is x

dollars, which statement is true about the rate of change of this linear model?

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.
