A12-foot by 15-foot patio is increased by placing a stone border around the patio. the width of the border is the same all around the patio. the perimeter of the patio after it is expanded is 74 feet. the equation which represents x, the width of the border is 2[(12+2x)+15+2x)]=74. what is the width of the border? 1) 2 1/2 feet 2) 3 feet 4) 5 feet 5) 8 1/2 feet

The correct answer is A) 2 1/2 feet

A. 2 1/2 feet.

(c, 0) i might be wrong so don't put full faith on my answer

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.
