Answer:
a)
b)
And adding these values we got:
c) We can find the expected value given by:
And the standard deviation would be:
We can use the approximation to the normal distribution and we have at leat 95% of the data within 2 deviations from the mean. And the lower limit for this case would be:
And then we can consider a value of 18 as unusual lower for this case.
Step-by-step explanation:
Let X the random variable of interest "number cleared by arrest or exceptional", on this case we can model this variable with this distribution:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
Part a
We want this probability:
Part b
We want this probability:
We can find the individual probabilities:
And adding these values we got:
Part c
We can find the expected value given by:
And the standard deviation would be:
We can use the approximation to the normal distribution and we have at leat 95% of the data within 2 deviations from the mean. And the lower limit for this case would be:

Step-by-step explanation:
<h3> The complete exercise is attached.</h3><h3></h3>The area of a rectangle can be calculated with this formula:
Where "l" is the lenght and "w" is the width.
Then, you can notice that it can be obtained by multiplying the dimensions of the rectangle.
Knowing this, you can determine that the total area of the two flowers bed can be obtained by adding the products of their dimensions.
Since one of the rectangular flower bed is 2.78 feet by 4.81 feet and the other bed 2.78 feet by 5.61 feet, you can write the following expression to find the total area (in square feet)of the two beds:
If you factor out 2.78:
or
Therefore, the expression that does not represent the total area in square feet of the two beds, is:
