Answer: 2.28%
Step-by-step explanation:
Given: An airport find that at the present time, the mean noise level is 103 decibels and the standard deviation is 5.4 decibels.
The distribution of noise levels(x) for all jets during takeoff over the neighborhood has a normal distribution.
The probability that jets have a noise level less than 92.2 decibels when taking off over this neighborhood will be :-
Hence, the percent of these jets have a noise level less than 92.2 decibels when taking off over this neighborhood = 2.28%
If you need to write a number as a decimal, it means that you need to write is a an x divided by a power of 10.
you can use this formula:
now let's multiply both sides by 10:
and simplyfy:
(by dividing the first fraction's elements by 5)
change improper fraction into a mixed number
and 1 over 3 is 0.33333...
so the answer is 1.333333 - we can also write it as 1.(3)
