Answer:
<h3>1 gallon of paint can cover 60 square feet of wall.</h3>Step-by-step explanation:
We are given that 2 1/2 gallon of paint can cover 150 square feet of wall.
We need to find the the number of square feet that 1 gallon of paint can cover.
In order to find the number of number of square feet that 1 gallon of paint can cover, we just need to divide 150 square feet by 2 1/2 gallon.
2 1/2 gallon in decimal form could be written as 2.5 gallons.
Dividing 150 square feet by 2.5 gallon, we get

Answer:
At least 75% of these commuting times are between 30 and 110 minutes
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 .
In this question:
Mean of 70 minutes, standard deviation of 20 minutes.
Since nothing is known about the distribution, we use Chebyshev's Theorem.
What percentage of these commuting times are between 30 and 110 minutes
30 = 70 - 2*20
110 = 70 + 2*20
THis means that 30 and 110 minutes is within 2 standard deviations of the mean, which means that at least 75% of these commuting times are between 30 and 110 minutes
