Answer: x= 10
Step-by-step explanation:
Same side exterior angles sum to 180.
Using this axiom we can say that
142+ (3x+8) = 180
Add like terms on the left side
150+ 3x = 180
Subtract 150 from both sides
3x = 30
Divide both sides by 3
X= 10
Answer:
Step-by-step explanation:
The top graph seems to be nonlinear because the way its formed and the bottom linear since its straighter and the plots are closer together.
Sorry if im incorrect
For this case the first thing you should know is that if the coefficient of determination (R) is equal to 1, the graph is totally perfect.
Therefore, the closer the value of R is to one, the mathematical model will be the most appropriate.
We have then:
The coefficient of determination for the linear model was 0.95.
Therefore, the mathematical model must be linear.
Answer:
A model that should be used to represent the data set is:
A linear
The Formula to find the Area of a circle using the radius is:
r = 8
So:
And you get about 201.06193
So, the area of a circle with a radius of 8 is about 201.06
Hope this Helps :)
