-
Use the regression capabilities of a graphing utility to find a linear model of the form f(t) = mt + b for the data.
-
In the model, f(t) represents the number of attendees (in millions of people) and t represents the year.
f(t) = 0.189t – 378.543
-
Use a graphing utility to plot the data and graph the model. Insert a picture of the graph.
-
How does the model compare with your data – choose two years to compare?
-
Use your model to predict how many people will attend The Eras Tour in 2023.
I love this idea, Nigel. A much more interesting problem for the students. Plus, they could more easily see real-world applications of the math. I'm sure Swift and her management would want to predict attendance of a world tour before booking venues and planning.
Nigel, you must invite me to your next interesting problem class… I want to see and hear about how the students react to the problems
