Answer:
The probability is an Empirical Probability
Step-by-step explanation:
The empirical probability (also know as relative frequency, or experimental probability) is the type of probability that involves the ratio of the number of outcomes in which a certain occurrence or event happens to the total number of trials, not in a theoretical sample space but in an actual experiment.
It uses the number of occurrences of an outcome within a sample set as a basis for determining the probability of that outcome.
Answer:
76 degrees.
Step-by-step explanation:
Let as consider O is the center of the circle . So from the figure it is clear that
By central angle theorem, central angle subtended by an arc is twice of inscribed angle of the same arc.
We know that, 
and angle BOD is the central angle subtended by arc BD.
Now,
Therefore, the measure of arc BC is 76 degrees.

I just took the test and got it right
2nd one - y = 3/7x + 6 , hope this helps:)
Answer:
Step-by-step explanation:
- Total distance = 10 miles
- Total time = 2 hours
- Distance walked = x
- Speed walked = 2 mph
- Distance cycled = 10 - x
- Speed cycled = 15 mph
<u>Using the given data we can have the equation below to the time:</u>
- x/2 + (10 - x)/15 = 2
- 30x/2 + 30(10 - x)/15 = 30(2)
- 15x + 20 - 2x = 60
- 13x = 60 - 20
- 13x = 40
- x = 40/13
- x = 3.08 miles <em>rounded to 2 decimal places</em>
