To find: Equation of the line of best fit and the value of

Answer to Problem 11PPE
Using graphical calculator, the best of line fit, related to given data set is
Explanation of Solution
Given information: The below table shows the data set, used to get the line of best fit.
Concept used: Enter year values as first data set and enter tickets sold as second data set in graphics calculator.
Calculation: Plot years as x values on x axis and tickets sold as y values along y axis, so that to find the related line of best fit as
Calculate tickets sold in year 2014, by plugging
Conclusion: Required tickets sold in U.S in year 2014 are 1640.

They are playing a game where they randomly pick a card out of the hat four times, with replacement. Amy thinks that the probability of getting exactly two aces in four picks is equal to the probability of not getting exactly two aces in four picks. Samiha disagrees. She thinks that the probability of not getting exactly two aces is greater. The sample space of possible outcomes is listed below. A represents an ace, and K represents a king.
