Answer:
C
Step-by-step explanation:
THe mean deviation is the sum of all the differences of the values from the mean and then we divide by the number of values in the data set.
First, lets find the mean (sum of all the numbers divided by number of numbers):
Mean = (271+354+296+301+333+326+285+298+327+316+287+314)/12 = 309
Now, the mean deviation:
|(271-309+(354-309+(296-309+.....(314-309))|/12 = <u>19.33</u>
<u>The mean absolute deviation (MAD) is equal to 19.33</u>
<u>Correct answer is C</u>

Explanation:
The sine of any acute angle is equal to the cosine of its complement. The cosine of any acute angle is equal to the sine of its complement. of any acute angle equals its cofunction of the angle's complement. Yes, there is a "relationship" regarding the tangent of the two acute angles (A and B) in a right triangle.
