Hi there
Replace the blank space by x
so x/7 > 800
All you have to do is cross-multiply
x > 7*800
x> 5600
I hope that's help !
J/9=5
Multiply both sides by 9
Which gets you
j = 45

Answer:
y=-5x+7
Step-by-step explanation:
Prallel lines have the same slope
so the slope of the unknown line is -5
and passes through(1,2)
y-2=-5(x-1)
slope-intercept form:y=-5x+7
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%.
