From the mean of 13,
the value of the stated summation will be given by:
(5.7-13)+(10.2-13)+(11.9-13)+(13.3-13)+(17.6-13)+(19.3-13)
=-7.3+(-2.8)+(-1.1)+0.3+4.6+6.3
=0
Hence the summation indicated also known as mean absolute deviation is 0.
Answer: C. 0
The tangent function has a period of π or 3.14. The period is the point where the graph touches the x-axis. The graph passes through 0 and then π. The next point is 2π. This goes on for the points nπ where n is any whole number.
