Answer:
D. It only benefits a handful of the world's countries is the correct answer.
Explanation:
<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
30+13.98=43.98
which we round to 44dB</span>

Answer:
real interest rate = -3.08%
Explanation:
real interest rate = nominal rate - inflation rate
- nominal interest rate = [($562/$509) - 1] x 100 = 10.41%
- inflation rate = [(143/126) - 1] x 100 = 13.49%
real interest rate = 10.41% - 13.49% = -3.08%
since the real interest rate is negative, the investor actually lost money in real dollars. This means that the amount of goods that the investor could purchase before making the investment is higher than the amount of goods he/she will be able to buy after the investment.
