This is the concept of probability and statistics, to get the summation of (x-μ) where μ is the mean will be given by:
(3.7-11)+(8.2-11)+(9.9-11)+(9.9-11.3)+(15.6-11)+(17.3-11)
=-7.3+-2.8+-1.1+0.3+4.6+6.3
=0
The answer is 0
Answer:
its 40
Step-by-step explanation:
1x20 = 20
and 2x20=40
For this case we have the following equation:

From here, we must substitute ordered pairs of the form:
(x, y)
If the ordered pair satisfies the equation, then it belongs to the line.
We have then:
For (8, 5):
We substitute the following values:

We observe that the equation is not satisfied and therefore, this point does not belong to the line.
Since one of the points does not belong to the line, then the equation is not a good model.
Answer:
It is not a good model. One of the points does not belong to the line.
