I think the answer is 21 you just multiply the number of weightlifters by the number of places so 7 x 3.
Angles 1 and 2 are linear, meaning that they are supplementary, or add up to 180 degrees. We already know that angle 1 = 72 degrees. So, to find angle 2, take 180 and subtract 72 from it to get: 180 - 172 = 108 degrees. The answer is B.
Answer:
328.4
Step-by-step explanation:
sorry I don't know the step by step
Building a probability distribution, it is found that the expected value for both players is of 0.25 points.
- The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.
In this problem, the four possible outcomes, considering Player A - Player B, are:
H - H
T - H
H - T
T - T
That is, considering a success as the number of heads, the distribution is:
For Player A, the earnings of each outcome are: -1, 0 and 2
Hence, the expected value is:
For Player B, the earning of each outcome are: 2, 0 and -1.
Hence:
The expected value for both players is of 0.25 points.
