J(5,3) and K( 7,3) are the endpoints of a chord of a circle. Which
information is needed to prove that is a diameter of the circle?
O A. (6, 3) is the center of the circle and the midpoint of JK
O
B. (1, 0) is the center of the circle and the midpoint of JK
C. (-1,0) is the center of the circle and the midpoint of
O
D. (-6,3) is the center of the circle and the midpoint of JK.

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.

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
