Answer:
On the average, estimates will be either be 0.2 meters too short or too long.
Step-by-step explanation:
Standard deviation is normally used to show how the actual value of a variable in a given sample deviates from the mean or average value of the sample. The deviation could be slightly more or less than the average value by the value of the standard deviation. Therefore, in this question, the standard deviation shows that the estimates could be 0.2 m short or more than the mean.
According to a daylight calculator for Fairbanks, AK, sun rises at 07:40 and sun sets at 20:12, giving 12 hours and 32 minutes of daylight.
Note that it is not a mistake that daylight is not exactly 12 hours on that day due to refraction of the sun's rays at sunrise and sunset.
At Fairbanks, near equality to 12 hours occurs on March 16 with sunrise at 07:58 and sunset at 19:57.
Answer: r≈6
Step-by-step explanation: Using the formula
C=2πr
Solving forr
r=C
2π=37.7
2·π≈6.00014
Answer:
2
Step-by-step explanation:
To figure this out, you must use the triangle inequality theorem. It says that the sum of 2 sides of the triangle should be more than the third side. If you add 8 and 12, you get less than 24 but if you add 12 and 24 or 8 and 24, you will get more. So, there are only 2 triangles! I hope this helps!
