Josiah measures the lengths of different banners around the school and records the lengths in both centimeters and meters. Which statement is true about the lengths of the school’s banners? The lengths in centimeters show that there is more variation in the data because the variance is 10,000 times greater than the variance of the lengths in meters. The lengths in meters show that there is less variation in the data because the variance and standard deviations are approximately equal. The lengths in both measurements have the same variation because they represent the same data in different units. The standard deviations of 99.1 centimeters and 0.991 meters are equivalent lengths. The variations of the lengths in centimeters and meters cannot be compared because the standard deviations are not equal.

Suppose someone opens the valve on a large water tank so that water drains out. Choose a starting volume of water in the tank (from 100 to 500 gallons), and choose how much water drains out each day (from 2 to 5 gallons). Write the equation that models the relationship between time (x) and water volume (y) in slope-intercept form. Post your equation. Choose another equation from the discussion board and answer the following. Write the equation in slope-intercept form, and use the equation to find the amount of water in the tank exactly 2 days after the valve is opened. Determine the slope of the line. Describe the meaning of the slope in this context. Rewrite the equation in standard form, and use that equation to find the x- and y-intercepts. Describe the meaning of each intercept. Do these equations represent an exact or approximate relationship between time and volume? This could be a matter of opinion. What is your opinion? Explain.
