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.

C: 1
Step-by-step explanation:
4x^2-4x=24
Subtract 24 from each side
4x^2 -4x -24 = 24-24
4x^2 -4x-24 =0
Factor out a 4 from each side
4(x^2 -x -6) =0
What 2 numbers multiply to -6 and add to -1
-3*2 = -6
-3 +2 =-1
4(x-3) (x+2) =0
4(x-3) (x- -2) =0
p=3 q =-2
p+q
