Cross multiply
72 x 2 = 15c
144 = 15c
Divide each side by 15
c = 9.6
The exact circumference is 60ft
Answer:
Option D (Yes. The model is a good fit because the residual plot does not have a random pattern).
Step-by-step explanation:
First of all, insert all the data in Microsoft Excel. Make sure that the values of X are in the ascending order. Then, make the scatter plot of the data with the line of best fit from the Insert option. The graph shows that there is a positive relation between x and y. Most of the actual values of y lie very close to the line. A very few observations are a little further from the line of best fit. Therefore, the model is a good fit because the residual plot does not have a random pattern. Option D is the correct answer!!!
