Data Analysis: Meteorology The table shows the maximum daily high temperatures in Las Vegas and International Falls (in degrees Fahrenheit) for month with corresponding to January. (Source: National Climatic Data Center) (a) A model for the temperatures in Las Vegas is Find a trigonometric model for International Falls. (b) Use a graphing utility to graph the data points and the model for the temperatures in Las Vegas. How well does the model fit the data? (c) Use the graphing utility to graph the data points and the model for the temperatures in International Falls. How well does the model fit the data? (d) Use the models to estimate the average maximum temperature in each city. Which term of the models did you use? Explain. (e) What is the period of each model? Are the periods what you expected? Explain. (f) Which city has the greater variability in temperature throughout the year? Which factor of the models determines this variability? Explain.
