From the information given, it should be noted that the values listed below are waiting times of customers at the Jefferson Valley Bank, where customers enter a single waiting line that feeds three teller windows.
The degree of freedom will be:
= 9 - 1 = 8

Answer:
Step-by-step explanation:
The angle forms arc . The measure of this arc is twice the measure of angle , since is a point on the circle. Since forms an arc , we can set up the following equation:
.
Since arc TU represents half of a circle and there are 360 degrees in a circle, we can substitute the following values and solve for the measure of arc VU:
I also think that is b but it could be d
