The perimeter of triangle XYZ will be:
40r + 30r + 60r = 130r
The area of triangle ABC is n² so the area of triangle XYZ will be n²×r²
Answer:
Automated menu
Live agent menu
So then we can conclude that we have lower variation for the Live agent menu since the coefficient of variation is lower compared to the Automated menu
Step-by-step explanation:
We can solve this by case
Automated menu
Data: 11.7 7.4 3.9 2.9 9.2 6.3 5.5
We can begin calculating the mean with the following formula:
And replacing we got:
Now we can calculate the standard deviation with the following formula:
And replacing we got:
Now we can calculate the coeffcient of variation with this formula:
And replacing we got:
Live agent menu
Data: 6.2 2.9 4.4 4.1 3.4 5.2 3.7
We can begin calculating the mean with the following formula:
And replacing we got:
Now we can calculate the standard deviation with the following formula:
And replacing we got:
Now we can calculate the coeffcient of variation with this formula:
And replacing we got:
So then we can conclude that we have lower variation for the Live agent menu since the coefficient of variation is lower compared to the Automated menu
