According to the empirical rule , 68% of the population falls within one standard deviations from the mean.
Given : For pigs, the length of pregnancies varies according to a normal distribution with a mean of 114 days and a standard deviation of 5 days.
According to the Empirical Rule, the length of approximately 68% of all pig pregnancies will fall between days and

Answer:
The width of the carpet is 12 inches and the length of the carpet is 120 inches.
Step-by-step explanation:
^We can distribute first^
Distributing would result in:
Then we would combine like terms, which would result in:
Then we solve the equation.
Since the width of the carpet is 12 (as we figured out). The statement said that "The length of the carpet is 108 inches more than the width."
So now we add 108 to 12 to figure out the length.
The length of the carpet is 120 inches.
