Answer:
m=15
Step-by-step explanation:
BODMAS
6m+6+7-3m=-32
collect like terms
6m-3m+6+7=-32
3m+13=-32
3m=-32-13
3m=45
m=45/3
m=15
The answer should be 339.1
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:

In conducting a goodness of fit test, a requirement is that the expected frequency must be at least ten for each category.
<h3>What is a
goodness of fit test?</h3>
In relation to the statistical model, the test tells how well it fits a set of observations.
The measures of the goodness of fit summarize the discrepancy between observed values and the values expected under the model in question.
Also, when conducting a goodness of fit test, a requirement is that the expected frequency must be at least ten for each category.
Therefore, the Option B is correct,
