Step-by-step explanation:
When the angle is measured in degrees, the formula of the area of sector is:
Given: r= 14m, θ= 90
Area of sector
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%
Answer:
C=1 ft
Step-by-step explanation:
c2= a2 + b2 - 2ab
= 8^(2) + 7^(2) - 2(8)(7)
= 113 -112
c2= 1 put a square root on c2 and 1
c = 1
Answer:
The value of the motorhome can be expressed as x - .35x
Step-by-step explanation:
This is because it has lost 35% of it's value. Therefore, we can subtract that from the original value to get its current value.
