Help me with this too pls

it would take 6 hours,

Step-by-step explanation:

it is raining 2 inches per hour, so adding on 2 inches for each hour you get 6 hours.

6 hours

Step-by-step explanation:

It would take 6 hours for it to reach to a foot.

The answer in it's ratio form would be 12/6 since 12 stands for the inches and 6 stands for hours.

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.

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
