Concept explainers
a.
To graph: The data of the table.
a.
Answer to Problem 91E
Explanation of Solution
Given: The table shows below,
Using graphing utility to plot the points and graph the model.
The
Now draw the model of data.
b.
To find: The rational model of the data.
b.
Answer to Problem 91E
Explanation of Solution
Given: The table shows below,
Take the reciprocal of A to generate the points
Using above part (a), the linear regression was
So, reciprocal of this,
So,
Now make new table of 1/ A
Now plot the points and rational model of the data.
c.
To find: The rational model of the data.
c.
Answer to Problem 91E
Explanation of Solution
Given: The table shows below,
Rational model,
Linear model,
Choose rational model because this model shows data perfectly. In this model output million per part. It shows as number of increase carbon monoxide amount increases.
