Answer:
68%
Step-by-step explanation:
<em><u>68-95-99.7% Rule:</u></em>
<em><u /></em>
This is the empirical rule which is used to remember the percentage of values that is within a band of the mean. We say:
- 68% of the data fall within 1 standard deviation of the mean
- 95% of the data fall within 2 standard deviation of the mean, and
- 99.7% of data falls within 3 standard deviations of the mean
Clearly, from the empirical rule, we see that about 68% of the area is between z = -1 and z = 1 (or within 1 standard deviation of the mean)
180.
4•9=36, and 36•9 is 324. 4•3 is 12, while 12•12 is 144.
324 - 144 = 180. I hope this helps!
The measurement of ∠1 is half of the central angle's length 120
120/2 = 60
60° is your answer
Reason: This is because an inscribed angle is half of the arc length.
A central angle is the same measurement as the arc length.
hope this helps
