Can i get with this question? attached an ss

12,000

Step-by-step explanation:

Let "a" represent the number of panels produced by Plant A. Then the number produced by Plant B is (a+7000). The total number of defectives is ...

... 0.04a + 0.02(a+7000) = 860

... 0.06a + 140 = 860 . . . . . . . . . . . . . simplify

... a = (860 -140)/0.06 = 12,000 . . . . solve for a

Plant A produced 12,000 panels yesterday.

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.
