If you would like to calculate the arithmetic mean, geometric mean, and harmonic mean from the following averages, you can calculate this using the following steps:
averages: 56.4, 59.8, 55.8
the number of values: 3
arithmetic mean:
(56.4 + 59.8 + 55.8) / 3 = 57.33
geometric mean:
(56.4 * 59.8 * 55.8)^(1/3) = 57.31
harmonic mean:
3 / (1/56.4 + 1/59.8 + 1/55.8) = 57.28
The spinner game is an illustration of probability, and the spinner game that is fair is (b) If you spin a number greater than 10, you win.
<h3>How to determine the fair game?</h3>
The number of sections in the spinner is given as:
n = 20
There are 10 numbers greater than 10 i.e. 11 to 2.
So, the probability that a number greater than 10 is spun is:
P = 10/20
P = 0.5
The probability that a number that is not greater than 10 is spun is calculated using the following complement rule
q = 1 - p
This gives
q = 1 - 0.5
Evaluate
q = 0.5
Notice that both probabilities are the equal
Hence, the spinner game that is fair is (b) If you spin a number greater than 10, you win.

Step-by-step explanation:
Double angle formulae involve trigonometric functions of double angles and in order to get its value you must consider the following:
-derive the double angle formula from additional formula
-write the formula for the angle in alternative form
-use the formula to write trigonometric expressions in different forms
-use the formula in the solution of trigonometric equations
And the answer would be 4sin(theta)cos(theta)cos(2theta)
