Rowan has 50$ in a saving jar and is putting in 5$ every week. jonah has 10$ in his own jar is putting 15$ very week. each of them plots his progress on a graph with time on horizontal axis and amount in the jar on the. vertical axis. which statement about their graph is true.
(a) rowan's graph has a steeper slope than johan's
(b) rowan's graph always lies above johan's
(c) johan graph had a steeper slope than rowan
(d) johan graph always lies above rowan

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope

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.
