Description
The perimeter of the rectangle is 18 square cm. What are the length and width? Which equation models this problem
8 • l = 18 –
8
l(l – 8) = 18
l + (8 + 2l) = 18
2l + 2(l – 8) = 18

Explanation & Answer
Let
Length = x
Width= x-8
Perimeter = 2 l + 2 W
18/2=l+w
9=l+w
9=x+x-8
9+8=2x
17=2x
X=17/2=8.5
Width = 8.5-8= 0.5
The answer2l + 2(l – 8) = 18

DescriptionIn this discussion, you will explore the zeros of polynomials.InstructionsStep 1: Respond to the following:Imagine you are writing exam questions for an algebra course. You want to write questions that include finding the zeros of polynomials. To balance the difficulty level of the test’s questions, you decide to include two different types of questions, as described here:Question #1: A polynomial of degree at least 3 where all the zeros are positive whole numbersQuestion #2: A polynomial of degree at least 3 where one or more of the roots are fractionsFind two polynomials for the two described questions. Explain how you know each question satisfies the requirements stated. What approach did you use to find these polynomials?*Be sure to cite any outside sources in APA format.

The Payment Time Case
Purpose of Assignment The purpose of the assignment is to develop students' abilities in using datasets to apply the concepts of sampling distributions and confidence intervals to make management decisions. Assignment Steps Resources: Microsoft Excel®, The Payment Time Case Study, The Payment Time Case Data Set Review the Payment Time Case Study and Data Set. Develop a 700-word report including the following calculations and using the information to determine whether the new billing system has reduced the mean bill payment time:Assuming the standard deviation of the payment times for all payments is 4.2 days, construct a 95% confidence interval estimate to determine whether the new billing system was effective. State the interpretation of 95% confidence interval and state whether or not the billing system was effective.Using the 95% confidence interval, can we be 95% confident that µ ≤ 19.5 days?Using the 99% confidence interval, can we be 99% confident that µ ≤ 19.5 days?If the population mean payment time is 19.5 days, what is the probability of observing a sample mean payment time of 65 invoices less than or equal to 18.1077 days?
