Question

The graph below shows a company's revenues in 2004, 2006, 2008 and 2010. The equations for the line of best fit and the parabola of best fit for the data are y = 9.2x + 2.68 and y = 1.36 x^2 + 1.06x + 8.1 respectively. In 2011, the company's revenue was 108.25 billion dollars. Use this information to complete parts (a) and (b) D. Guessing is okay What does the line of best fit predict the company's revenue to be in 2.11 (year 7)? billion dollars (Type an integer or a decimal) What does the parabola of best fit predict the company's revenue to be in 2011 (year 7)? billion dollars. (Type an integer or a decimal.) b. Which model is the better overall predictor of the company's revenue? A. The line of best fit B. The parabola of best fit Using the model that best fits the data provided, predict the company's revenue in 2020. billion dollars (Type an integer or a decimal.)

Explanation / Answer

predition to be in 2011 from line of best fit =9.2*7+2.68=67.08 billion dollars

predition to be in 2011 from parabola of best fit =1.36*72+1.06*7+8.1=82.16 billion dollars

b)

option B ; parabola of best fit

c)predition to be in 2020 from parabola of best fit =1.36*162+1.06*16+8.1=373.22 billion dollars
