It is given in the question that
If four angles of a convex pentagon measure 120°, 93°, 108°, and 101°, find the measure of the fifth angle.
First we have to find the sum of measurement of all the angles of a convex pentagon, by using the formula
Where n is the number of sides. And for polygon, it is 5 .SO the sum of measurement of angles of a polygon is
Let the measurement of missing angle be x .
So we have
Given the model of the Exponential Regression:
By definition:
You can see in the table the observed y-values (the temperature in Fahrenheit)
In order to find the Predicted y-values, you need to substitute all the x-values given in the table (the time in minutes) into the equation and then evaluate. You get:
Now you have these points:
Therefore, you can plot them on the Coordinate Plane:
By definition, when the residual plot shows a pattern, a non-linear regression model is appropriate for the data. Therefore, the Exponential Regression Model is a good fit.
Hence, the answer is:
- Residual Plot:
- First option.
