The international shark attack file recorded the number of shark attacks between 1837 and 2016 for 8 different u.s. states.
elena-s [515]

The mean of the data given 4, 8,5, 13, 3, 4, 1, 10 shows number of shark attacks over 8 different states is 6.

As given,

Number of different states 'n'= 8

Number of sharks attacks for 8 different states

x_{i} = 4, 8,5, 13, 3, 4, 1, 10

Mean = \frac{\sum x_{i} }{n}

         = (4+ 8+ 5 + 13 + 3 + 4 + 1 + 10) /8

         =48 /8

         =6

Therefore, the mean of the data given 4, 8,5, 13, 3, 4, 1, 10 shows number of shark attacks over 8 different states is 6.

so supplementary is 180 degrees
complementary is 90 degrees
