The bar graph shows the ratings of American Idol from season 1 (2002) through season 12 (2013). a. Let x represent American Idol’s season number and let y represent the average number of viewers, in millions. Use a graphing utility to draw a scatter plot of the data. Explain why a quadratic function is appropriate for modeling these data. b. Use the quadratic regression feature to find the quadratic function that best fits the data. Round all numbers of two decimal places. c. Use the model in part (b) to determine the season in which American Idol bad the greatest number of viewers. Round to the nearest whole number. According to the model, how many millions of viewers were there in that season? Round to one decimal place. d. how do the results obtained from the model in part (c) compare with the data displayed by the graph? e. Use a graphing utility to draw a scatter plot of the data and graph the quadratic function of best fit on the graph had the producers of American Idol looking for a shake-up? No shake-up was found and the show’s final season aired in 2016.

Solution Summary: The author explains how to graph the scatter plot of the data using a graphing utility.
The bar graph shows the ratings of American Idol from season 1 (2002) through season 12 (2013).
a. Let x represent American Idol’s season number and let y represent the average number of viewers, in millions. Use a graphing utility to draw a scatter plot of the data.
Explain why a quadratic function is appropriate for modeling these data.
b. Use the quadratic regression feature to find the quadratic function that best fits the data. Round all numbers of two decimal places.
c. Use the model in part (b) to determine the season in which American Idol bad the greatest number of viewers. Round to the nearest whole number. According to the model, how many millions of viewers were there in that season? Round to one decimal place.
d. how do the results obtained from the model in part (c) compare with the data displayed by the graph?
e. Use a graphing utility to draw a scatter plot of the data and graph the quadratic function of best fit on the graph had the producers of American Idol looking for a shake-up? No shake-up was found and the show’s final season aired in 2016.
Formula Formula A polynomial with degree 2 is called a quadratic polynomial. A quadratic equation can be simplified to the standard form: ax² + bx + c = 0 Where, a ≠ 0. A, b, c are coefficients. c is also called "constant". 'x' is the unknown quantity

Amy and Samiha have a hat that contains two playing cards, one ace and one king. 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. Who is correct?
Consider the exponential function f(x) = 12x. Complete the sentences about the key features of the graph.
The domain is all real numbers.
The range is y> 0.
The equation of the asymptote is y = 0
The y-intercept is 1
