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%
6(8)+b/6
48+b/6
b/6=-48
b=-48/6
b=-288
It would be 20 because the highest number is 25
Answer:
b) in the fourth round, there was one team left in the tournament.
c) no because with only one team left, the tournament ends.
F(1) = -2
