A portion of a circular rainbow is to be painted on the wall. the inner edge of the purple strip is 4 feet from the center ( distance r). if the angle a=42.1 degrees, and the area of the rainbow ( from the purple to the red) is 100.298. what is the radius of the outer edge of the rainbow ( the distance R) ?

answer: for each 3 girls there is 2 boys . 3: 2

hope this ! (:   mark me as brainliest if you can

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.

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
