Learning outcome:
Upon completion student will be able to: * Given linear and exponential data, interpret the rate of change within the given context. * Represent linear and exponential models as equations, tables, graphs and verbal descriptions.
Scoring/Grading rubric:
Each question is worth 10 points.
Introduction:
Everyone has had some experience with gossip. In this lab, you will explore how well rumors (or secrets) spread when this information is passed on to other people.
Scenario A: At noon, you get some great news but you need to keep it a secret. It’s just too good to keep to yourself; so 5 minutes after you get the news you call 2 friends and tell them, but swear them to secrecy.

How many people know your secret at 12:40 in Scenario A?
In Scenario B?
2. Describe the pattern of growth in the “Number of people told” column for both Scenario A and Scenario B.
3. Describe the pattern of growth in the “Number of people who know” column for both Scenario A and Scenario B.
4. Write an equation to find the “Number of people told” for any 5-minute interval(n) in
Scenario A.
5. Write an equation to find the “Number of people told” for any 5-minute interval in Scenario B.
6. Write an equation to find the “Number of people who know” for any 5-minute interval in Scenario A.
7. Write an equation to find the “Number of people who know” for any 5-minute interval in Scenario B.
Using the equations you wrote in problems 4-7, create an Excel spreadsheet with the columns “5-minute interval,” “Number of people told,” and “Number of people who know”. Make sure your spreadsheet matches your tables above before answering the following questions. 8. After how many minutes would at least 100 people know in Scenario A?
In Scenario B?
9. According to the 2012 US Census, the population of NC is 9,752,073. Using Scenario B,
4) Use exponential regression (or find a constant ratio) to determine an equation for the data.

5. Since the distribution D1 no longer holds, there exist a new distribution where everyone has 0.25 less than original and Wilt Chamberlain has 250,000 more than original
B. In order to solve for the rate, we would first begin dividing by twenty. That would give us 5.5. We would then set that equal to one plus r in parenthesis to the power of 10. Then, would bring the power of ten and make it an index to the square root of 5.5 and still have it equal to one plus r in parenthesis. We would then further simplify the square root of 5.5 and the index 10. It would give us a long decimal but rounded to 1.19. I would further subtract it by one.
