1) Find the mean, median, mode, and range of the data set.
A student’s first semester Algebra 2 quiz scores: \(98, 75, 80, 92, 86, 80\)
2) Use your calculator to find the mean, median, and range of the data set. Give the mode as well.
Winning distances (in meters) in the men’s Olympic triple jump events from 1964-2004:
\(16.85, 17.39, 17.35, 17.29, 17.35, 17.26, 17.61, 18.17, 18.09, 17.71, 17.79\)
3) Find the mean, median, mode, and range of the data set. You can use your calculator or do it by hand.
The wait times for customers (in minutes) at a fast food drive through over a \(10\) minute span were:
\(2.5, 1.2, 3.1, 4.8, 1.3, 0.8, 2.4, 2, 3.1\)
4) Using the same data from #3...
a) Increase each waiting time by \(5\) minutes. Find the new mean, median, mode, and range.
b) Summarize what happened to the mean, median, mode, and range when you added this constant value.
5) Using the same data from #3...
a) Multiply each waiting time by a constant of \(3\). Find the new mean, median, mode, and range.
b) Summarize what happened to the mean, median, mode, and range when you multiplied by this constant value.
Review Problems
6) If you purchase a home for \(\$240,000\) and expect the value of the home to increase by about \(2.1\%\) per year, how much can you expect the home to be worth in \(20\) years?
7) Expand \(\log_4 (\frac{x^2 y}{\sqrt{z}})\).
8) Without graphing, explain how you know that \(f(x)= \cos (x) -3\) has no x-intercepts.
9) If a person travels around a \(40\) foot radius ferris wheel \(8\) times, what linear distance did they travel?
10) An investor wants to double their money within \(10\) years, they are looking at accounts that compound their interest continuously. What is the minimum annual interest rate the account can offer to meet the investors goals?
