Answer:
For 6: A
For 7: B
Step-by-step explanation:
It requires graphing. For circumcenter, you draw a perpendicular line from each vertex to opposite side of that vertex and the intersection of those lines is the point of circumcenter.
Answer: False
Step-by-step explanation: To find the mean time add all the times and divide by the amount of times you have, which is 9.
0 + 15 + 30 + 90 + 105 + 120 + 45 + 60 + 75 = 540 total minutes spent.
Now divide 540 by 9 to get the mean time. 540 divided by 9 = 60.
So the mean is 60 minutes, not 75 minutes.
Therefore the statement below is False.
The expected value formula is

We know that there are 125 tickets, so the probability of the ticket is

Then, we find the expected value

<h2>Hence, the expected value is $7.60.</h2>
