Question

Find the arithmetic mean of the values of sin 0, sin30, cos60,
tan 45º and cot 45°​

Answer 1

Step-by-step explanation:

sin0 = 0

sin30 = 1/2

cos60 = 1/2

tan45 = 1

cot45 = 1

arithmetic mean = sum of all observations

                              total number of observations

                          = 0+ 1/2 + 1/2 + 1 + 1      =   4/5 = 0.8

                                   5

                           

Answer 2

arithmetic mean = 0.6

Step-by-step explanation:

given data

a = sin 0  = 0

b = sin30  = 0.5

c = cos60  = 0.5

d = tan 45º  = 1

e = cot 45°  = 1

solution

we get here arithmetic mean that is express as

arithmetic mean = $\frac{a+b+c+d+e}{5}$      .................1

here put all these value in equation 1 we get

arithmetic mean = $\frac{0+0.5+0.5+1+1}{5}$

arithmetic mean = $\frac{3}{5}$  

arithmetic mean = 0.6
