Answer:
0.67% probability he will have to shut down after this month
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
On average sells 8.9 machines per month.
So 
Using the Poisson distribution, what is the probability he will have to shut down after this month
If he sells less than 3 machines.






0.67% probability he will have to shut down after this month
You are given
the surface area of the cube which is 96cm2. You are asked to find the length
of one side and its volume. Note that the surface area of the cube is equal to
6 times the square root of s (the side of the cube) and the volume is the cube
root of s. So,
SA = 6*s^2
96cm2 = 6*s^2
s^2 = 16cm
<u>s = 4cm,
this is the length of one side.</u>
V = s^3
V = (4)^3
<u>V = 64cm3,
this is the volume of the cube.</u>
Answer:
Increase
Step-by-step explanation:
Precision describes the closeness of estimates from different samples, it refers to the width of the confidence interval and can aso be described as the margin of error. While the confidence level describes the accuracy.
Going for a higher confidence level will bring about a wider confidence interval, and thus lead to a less precise estimate.
