Answer:
The three sides are 27 feet, 15 feet, 13 feet
Step-by-step explanation:
Let second side of a triangle be = a
Let one side be 12 feet shorter than the second side = (a - 12)
Let the third side be 2 feet shorter than the second side= (a - 12) - 2 =(a - 14)
Perimeter of triangle = Sum of length of all 3 sides
55 = a + (a - 12) + (a - 14)
55 = a + a + a - 12 - 14
55 = 3a - 26
55 + 26 = 3a
81 = 3a
a = 27
Length of one side, a - 12 = 27 - 12 = 15 feet
Length of second side, a = 27 feet
Length of third side, a - 14 = 27 - 14 = 13 feet
Answer:
Minimum percentage = 88.89%
Step-by-step explanation:
We are given the following in the question:
Mean, μ = 95 dB
Standard Deviation, σ = 8 dB
Chebyshev's rule:
- According to this rule atleast percent of data lies within k standard deviation of mean.
We have to find the minimum percent of data lying within 3 standard deviations of the mean.
Putting values, we get,
Thus, minimum 88.895 of data lies within 3 standard deviations of the mean.
