The shape is a quadrilateral, because it has four sides.
And sum of angles in a quadrilateral = 360 degrees.
The angle with no number but just a symbol = 90 degrees.
From the fourth angle been M:
Therefore: 90 + 62 + 127 + M = 360
279 + M = 360
M = 360 - 279
M = 81
M = 81°
Option C.
I hope this explains it.
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
y2-y1/x2-x1
Y(subscript 2) - Y(subscript 1) / X(subscript 2) - X(subscript 1)
It’s 3/5 since it should be adjacent/hypotenuse and 4 is the opposite
