Set up a system of equations.
l=4w
2l+2w=110
Substitute l in to the second equation.
2(4w)+2w=110
8w+2w=110
10w=110
w=11
Substitute w back into the first equation.
l=4(11)=44
So, the length is 44 feet and the width is 11 feet.

Answer:
The probability that a person is audited more than twice is 0.0037
.
Step-by-step explanation:
We are given that The chance of an IRS audit for a tax return with over $25,000 in income is about 2% per year.
We are interested in the expected number of audits a person with that income has in a 16-year period
Now we are supposed to find the probability that a person is audited more than twice.
So, We will use binomial distribution
So, Probability of success =p= 2% = 0.02
So, Probability of failure = q=1-0.02=0.98
n = 16
Now we are supposed to find the probability that a person is audited more than twice i.e. 
So, 
Formula :
So,
Hence the probability that a person is audited more than twice is 0.0037
.

Discrete data refers to things that come in whole number amounts, whereas continuous data can have fractional amounts. Discrete data would be like the number of books on a shelf. Continuous data would be like the weight of a book in pounds. Since there are not fractions of a step in a stairway, we'd say that this number is discrete data.
Answer:
The best estimate of the proportion of adults who say that the law goes easy on celebrities is 0.7435.
Step-by-step explanation:
Confidence interval concepts:
A confidence interval has two bounds, a lower bound and an upper bound.
A confidence interval is symmetric, which means that the point estimate used is the mid point between these two bounds, that is, the mean of the two bounds.
In this question:
CI is between 0.645 and 0.842. So the best estimate of the proportion is:
(0.645+0.842)/2 = 0.7435
The best estimate of the proportion of adults who say that the law goes easy on celebrities is 0.7435.
