<span>Assuming a normal distribution the noise level is below 44dB 90% of the time.
Looking up the standard deviation that goes along with .01 on a normal distribution chart, we find that 2.33 standard deviations is the answer. Given the standard deviation of six we turn this in to deviation in decibels from the mean:
6*2.33 = 13.98
Add this to the mean to get

which we round to 44dB</span>
The answer is a I believe I'm not really sure

480,000 / 8 new useful life = 60,000 depreciation per year.
