Answer: 3.42
Step-by-step explanation: use trig equations. Sin 20 = x/10. Multiply both sides by 10. Sin (20) times 10 is 3.42
The answer rounded would be .83. I got this by writing out the equation each hour. For example, 1/2+1/2+1/2+1/2+6+1/2+1/2+1/2+1/2+0+0+0 = 10. Then, to find the average you divide them out by the amount of numbers. This would give you 10 divided by 12.
