A Review of Averaging Formulas
Math 1010 Intermediate Algebra Group Project
The Story:
Alyssa works for an online company that helps thousands of small business owners across the country to advertise themselves and find customers in need of their services
After the job is completed, Alyssa’s company encourages the customers to review the business on a scale of I to 5 stars Hiis review is saved within Alyssas database so that future customers can see the average number of stars a business has received on the online service That way the customers can find the best rated person for the job
Alyssa found that many business owners had questions about how they could improve their rating One common question was How nnm> 5-sl»r reviews in a row do 1 need to improve my rating from where Im at to a 4.5?- Or a 4.2? Or whatever threshold they were interested in0 Rather than having to work this out from scratch in every scenario, it is more efficient to create a formula so the answer can be found quickly and efficiently.
We will start out with some simpler questions to become familiar with the situation and how av erages work By the end of this project, you will be able to efficiently answer the question above for ANY starting situation You will use skills you learned about solving formulas for a particular variable and working with rational expressions
AVERAGES
We will be exploring how basic averages work in this section. This Average is also called the Mean, or Arithmetic Mean
1. Write a formula which can find the av erage of the two numbers X and Y AVERAGE=
2. Use your formula to find the av erage of 16 and 34 Show your process AV ERAGE –
3. Explain in words How docs the process of finding the average change if there are 6 numbers to average9
