new campaign titled “Ninety by Thirty.” The goal of the campaign was to increase the district’s
graduation rate to 90% by the year 2030.
The graduation rate for the years following the start of this campaign are given in the table below.
| Year | 2010 | 2011 | 2012 | 2013 | 2014 | 2015 | 2016 | 2017 | 2018 | 2019 | 2020 | 2021 |

Graduation Rate(%) |
62 | 63 | 65 | 66 | 67 | 67 | 65 | 68 | 70 | 70 | 71 | 71 |
Your job is to decide if the district is on track to reach their goal of 90% by 2030.
Start by creating the following:
1. An accurate and labeled graph of the district’s graduation rates over time, using the data from
the table above.
2. A list of the topics we’ve learned about in this course that would be helpful in solving this
problem.
Then use those to provide:
3. Predictions for the graduation rates for the next 5 years (2022, 2023, 2024, 2025, 2026). Show
your work and explain your approach.
4. A well supported conclusion. Is the district on track to reach its goal of a 90% graduation rate by
the year 2030? Why or why not?
Please show your work on a separate piece of paper or document, using complete sentences when
appropriate.
