Explanation of Solution
Given information: The below table shows the data related to average price and number sold.
Years | 1990 | 1992 | 1994 | 1996 | 1998 | 2000 | 2002 | 2004 | 2006 |
Revenue | 5.7 | 6.5 | 7.0 | 7.9 | 8.7 | 9.6 | 9.9 | 10.8 | 11.5 |
Concept used: In XY coordinate plane, years is represented on horizontal x axis and revenue ( in billions dollars) is represented on vertical y axis..
Calculation: Two data sets, on plotting in XY plane, show the related scattered plot as:
And as in year 2004, attendance is 328 and in 2006, it is 335, so estimated attendance in year 2005 will be 330 million.
Conclusion: Scatter plot shows that there is a strong

- The Colossus Ferris wheel debuted at the 1984 New Orleans World's Fair. The ride is 180 ft tall, and passengers board the ride at an initial height of 15 ft above the ground. The height above ground, h, of a passenger on the ride is a periodic function of time, t. The graph displays the height above ground of the last passenger to board over the course of the 15 min ride.
