Answer:
Is there any pictures to go with the question?
Step-by-step explanation:
Answer:
B= 32.11
A= 52.82
C= 95.07
Step-by-step explanation:
To find these angles, since you have all sides, you will need to use the law of cosines.
From the given discrete distribution, we have that:
<h3>What are the mean, the variance and the standard deviation of a discrete distribution?</h3>
- The mean of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.
- The variance is given by the sum of the difference squared between each observation and the mean, divided by the number of values.
- The standard deviation is the square root of the variance.
In this problem, the distribution is:
Hence, the mean is:
The variance is:
The standard deviation is:
