Not independent : An event is Not independent if the outcome of one event effect the outcome of other event.
1. A jar contains twenty coins. Two coins are picked randomly without replacement.
Not Independent because if coins are not replaced the outcome of next event will be effected.
2. A coin is flipped three times.

Solve like an algebraic equation
C= 2(3.14)r
remove ( )
C- 6.28r
divide by 6.28
C/6.28=r
hope this helps
Answer:
step 6 has an algebraic error
1. 2700 degrees. 450 rotations in on minute is 450(360) degrees per minute. If you divide this by 60 you get 2700.
2. 180 degrees. 4.3 rotations per minute is 4.3 times 360 degrees per minute. Multiply that times 5, and divide the answer by 360 and you get 21.5, which means he is 180 degrees from his starting point.
