Answer:
By the Chebyshev Theorem, at least 75% of commuters in Boston has a commute time within 2 standard deviations of the mean
Step-by-step explanation:
Chebyshev Theorem
The Chebyshev Theorem can also be applied to non-normal distribution. It states that:
At least 75% of the measures are within 2 standard deviations of the mean.
At least 89% of the measures are within 3 standard deviations of the mean.
An in general terms, the percentage of measures within k standard deviations of the mean is given by
.
What minimum percentage of commuters in Boston has a commute time within 2 standard deviations of the mean
By the Chebyshev Theorem, at least 75% of commuters in Boston has a commute time within 2 standard deviations of the mean
I think this is right -39+26i
The answer is $1,051.17 if I’m not mistaken
Answer:
your answer would be become 11 feet
2z−31=−9z+24
Add 9z to both sides.
2z−31+9z=−9z+24+9z
11z−31=24
Add 31 to both sides.
11z−31+31=24+31
11z=55
Divide both sides by 11.
11z/11=55/11
z=5
