The length of a rectangle is 4 more than its width. The perimeter is 40 feet. What are the length and width of the rectangle?
Hint: The perimeter of a rectangle is given by the formula P = 2/ + 2w.
O The width is 13 ft and the length is 7 ft.
O The width is 7 ft and the length is 13 ft.
O The width is 8 ft and the length is 12 ft.
The width is 12 ft and the length is 8 ft.

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.
