Answer:
The minimum percentage of the commuters in the city has a commute time within 2 standard deviations of the mean is 75%.
Step-by-step explanation:
We have no information about the shape of the distribution, so we use Chebyshev's Theorem to solve this question.
Chebyshev Theorem
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 .
Applying the Theorem
The minimum percentage of the commuters in the city has a commute time within 2 standard deviations of the mean is 75%.
Answer:
4.58 ft
Step-by-step explanation:
Pythagoras Theorem:
a^2 +b^2 = c^2
b^2 = c^2 - a^
b^2 =11^2 - 10^2
b^2 = 121 - 100
b^2= 21
the heigh = √21 = 4.58
Answer: 4.58 ft
