Answer:
The minimum percentage of noise level readings within 8 standard deviations of the mean is 98.44%.
Step-by-step explanation:
When we do not know the shape of the distribution, we use the Chebyshev's Theorem to find the minimum percentage of a measure within k standard deviations of the mean.
This percentage is:
Within 8 standard deviations of the mean
This means that 
. So
The minimum percentage of noise level readings within 8 standard deviations of the mean is 98.44%.
Answer:
x > 5
Step-by-step explanation:
Given that:
= -2(3x + 2) > -8x + 6
(negative sign before bracket will alter the internal signs when multiplied by each term)
= -6x - 4 > -8x +6
Taking x terms on left side and other constants on right side
= -6x + 8x > 6 +4
Signs will be changer for transferred terms
= 2x > 10
By Dividing both sides 2 we get
=x > 10/2
= x >5
Answer:
the answer would be B) no solution
Step-by-step explanation:
The two equations are parrael and that makes it have no solution.

Answer:
32d
Step-by-step explanation:
-The students ride their bikes to and from school every day. The distance is thus;
-Taking that there are 5 school days per week and that it rains in one per week. the total number of days is:
Now, we multiply the distance per day by the total number of days:
Hence, the total distance in a 4-week period is expressed as 32d ( where d is the distance from home to school).
Answer: y=5+4/5
Step-by-step explanation:
1) Move all terms to the left:
y-(29/5)=0
2) Add all the numbers together, and all the variables
y-(+29/5)=0
3) Get rid of parentheses
y-29/5=0
4) Multiply all the terms by the denominator
y*5-29=0
5) Multiply elements
5y-29=0
6) Move all terms containing y to the left, all other terms to the right
5y=29
y=29/5
y=5+4/5
