The document summarizes a student project analyzing the trajectories of North Korean and American missiles. It describes the roles of each student, how they calculated averages for distance traveled per hour and day, and how they used a graphing calculator to determine the line of best fit for each missile trajectory over eight days. The summary includes the equations for the lines of best fit and their point of intersection, representing when the missiles would collide.

1. Missile Project By Hailey Lape, Sarah Thomas, Julianna Fritzinger, Kristin Snyder

2. Roles Julianna- calculator works Hailey- checker and team leader. Kristin- technology Sarah- media designer and creative designer .

3. Averages To find the averages, we divided each distance (in miles) per day by 24 to find the miles per hour. Then we added all of the North Korean miles/hour together and divided by 8 to find the average miles/hour. We then added all of the American miles/hour by 8 to find the average miles/hour. Then we multiplied each of the average miles/hour distance by 1.609 to convert them into kilometers/hour. Then we multiplied each of the average km/hour by 24 to find the average km/day.

4. Line of Best Fit Directions Press Stat on the graphing calculater. Select edit 3. In “L1” we put the days in: 1, 2, 3, 4, 5, 6, 7, 8. 4. In “L2” we put the distance the North Korean Missile traveled from Earth in miles and the distance the American Missile traveled from Earth in miles: 10,311; 24,493; 48,238; 72,804; 99,649; 122,801; 151,224; 176,655; 0; 3,128; 33,203; 61,185; 90,233; 115,350; 145,514; 173,057. *After you each enter each value, press “ENTER”, so you can enter the next value. Use arrow keys to change the lists.*

5. Line of Best Fit Continued 5. Press “2 nd ” followed by “Y =” which takes you to the Stat Plot feature. 6. Select “Plot 1” and then press “Enter”. 7. Select the scatter plot graph. 8. Press “Stat” followed by highlighting “Calc” and pressing 4. Then. Press “Enter”. 9. Write down the values given for the slope, a, and the y-intercept, b. 10. Press “Y =” and enter the “ax+b” in to Y sub 1 substituting the values for “a” and “b” that you have written down.

6. 11. Press “GRAPH”. This is your line of Best Fit. 12. Your graph should look like this: Line of Best Fit Continued…

11. Conclusion

12. Possible Errors One error could be from typing the wrong number into the calculator which causes the Best Fit line to be completely different.
