Answer:
2.57
Step-by-step explanation:
The mean absolute deviation is the mean of the absolute values of the differences from the mean.
<h3>Application</h3>
The mean of the dataset is the sum of values, divided by their number:
mean = (20 +16 +21 +16 +22 +16 +15)/7 = 126/7 = 18
The absolute values of the differences from 18 will have an average of ...
mean(|differences|) = (2 +2 +3 +2 +4 +2 +3)/7 = 18/7
mad(data) ≈ 2.57

<em>Additional comment</em>
Some calculators have the mad( ) function built-in. See the second attachment, for example.
Answer:
The value is
The probability has increased
Step-by-step explanation:
From the question we are told that
The percentage that are from outside the country is
The percentage that logs on everyday is
The percentage that logs on everyday that are from the inside the country is
Generally using Bayes' Rule the probability that a person is from the country given that he logs on the website every day is mathematically represented as
Where is the percentage that are from inside that country which is mathematically represented as
And is percentage that logs on everyday that are from the outside the country which is evaluated as
Given that the percentage that are from inside that country is
and that the probability that a person is from the country given that he logs on the website every day is
We see that the additional information increased the probability

Answer:
The equation is:
The sum is:
--------------------------------------------------------------------
If the sequence is infinite, the formula is:
-------------------------------------------------------------------
Step-by-step explanation:
We must calculate the radius of the geometric series
The first term of the series is:
The last term of the series is:
If the sequence is finite then the formula is:
If the sequence is infinite then by definition as the radius are then the formula for the sum of the geometric sequence is:
