The average rate of change in attendance from 2011-2021 is 1.132 per year
From the graph, we have:
The average rate of change is then calculated as:
Rate = (58.77 - 47.45)/(2021 - 2011)
Evaluate
Rate = 1.132
2022 is 11 years from 2011.
So, the predicted annual attendance for 2022 is;
Attendance = 47.45 + 1.132 * 11
Attendance = 59.90
The years with unusual growth are 2020 and 2021.
This is so because they have the same attendance.
The factor that might have contributed to the anomalous growth include
In (a), we have:
Attendance = 47.45 + 1.132 * 11
Express as a function
y(t) = 47.45 + 1.132(t)
2025 is 14 years from 2011.
So, we have:
y(14) = 47.45 + 1.132(14)
y(14) = 63.298
2030 is 19 years from 2011.
So, we have:
y(19) = 47.45 + 1.132(19)
y(19) = 68.958
The factors include:
