If a plant grows 1/2 inch in 3/7 of a week, how many inches per week is the plant growing?

Assuming you want the rate per one week.

1/2 ÷ 3/7 = x / 1

(1/2)(7/3) = x

7/6 = x

1 1/6 = x

The plant grows one and one-sixth inches in a week.

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.
