3/8
Rise/Run, find a point and determine how high (rise) you have to go from the x- axis. Then find out how far right or left you have to go from the y- axis (run). Divide Rise by Run.
Wow ! That's some cosine !
No angle has a cosine greater than ' 1 '.
The question has no answer.
Sometimes...
2^-3 = 1/(2^3) = 1/8
-2^-3 = 1/(-2^3) = -1/8
Elements of sample space = 8
Elements of sample space are the possible outcomes involved in the event. In this case, there are 4 possible outcomes in pulling out one marble since there are 4 available marbles and another 2 outcomes for the tossing of coins. If it is a combined event, then multiplying the different possible outcomes of each event will give the elements of the sample space.
4 * 2 = 8
( - 4, 4) ; ( -4 , -2 ); ( 2 , - 2) would be the answer:)
