The oven was at room temperature 70℉. Just after it was turned on, the temperature rose 40℉ per minute. What does the independent variable represent? What does the dependent variable represent? Graph your results. Be sure to graph the independent variable on the horizontal axis. What will the temperature of the oven be after 6 minutes? Write an algebraic model (equation) for this application. How long will it take before the temperature is 450℉.

You are interested in the effect of room temperature on how well students do at memorizing a list of unrelated words. You randomly assign half of the student participants to a cool room and half to a warm room. You then give each group the list of words. After showing them the list, you have them write down as many words as they can remember (a free-recall task). What is the independent variable? What is the dependent variable?

Find an image on the Internet of a linear regression graph. The image you choose should have the horizontal and vertical axes labeled with units and you should be able to locate the regression equation. If you are stuck, search for linear regression. For the image you chose: What does the slope of the equation represent in terms of the units on the axes? What do the x-intercept and y-intercept represent in terms of the units on the axes? Identify...

Murder Investigation: When a glass of wine with a certain temperature is placed into a room, its temperature will converge to the room’s temperature according to the formula: F(t)=Fs+(F0-Fs) -.3t. Where F(t) is the temperature of the object after being in the room for t hours, F0 is the initial temperature of the object, and Fs is the temperature of the room that the object is in. Use this formula to investigate the scenario below and answer the following questions....

Task #1: Respiration Rate Changes in Minnows as a Function of External Temperature (adapted from exercise developed by Daphne McKay) Introduction Counting gill cover movements is a way to calculate respiration rates in fish. Fish breathe by taking water in through the mouth and forcing it over the gills when the mouth closes. An oxygen-carbon dioxide exchange occurs. Then the operculum opens to allow the carbon dioxide-rich water to exit. The respiration rate changes in response to changes in the...

Excel Lab 2: Regression and Goal Seek In this lab, you will use Excel to determine the equation of the model which best fits a set of ordered pairs obtained from data sets. You will enter data, graph the data, find the equation for the regression model, and then use that equation to make predictions for the dependent variable. You will use the goal seek to make predictions for the independent variable. Then you will consider how accurate your predictions...
