Andrea has a part-time job at the local grocery store. She saves for her vacation at a rate of $15 every week. Find her rate of change.
Solution
Begin by finding two ordered pairs. You can make a chart or use the Substitution Property to find two
coordinates. After 2 weeks of saving, she will have $30. After 10 weeks of saving, she will have $150. So we will use
the points (2, ) and (10, to determine our slope.
Use the formula:
M=
m =
150-30 dollars
10-2 weeks
m =
dollars
weeks
15 dollars
1 week
Andrea's rate of change is $15 per week.
m =

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.

step-by-step explanation:

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
