Make a
Calculation:
The slope of the line is positive and the points are close to the line.
The slope of the line is negative and the points are not close to the line.
No correlation:
There is no obvious pattern of increase or decrease for the given data.
Consider the table provided into textbook.
Graph the data as ordered pairs with the month on the horizontal axis and Gallons sold on the vertical axis. Let
Use maple to graph a scatter plot and a line of fit.
Suppose
The data show a strong positive correlation.
b.
Use two ordered pairs to write a prediction equation.

- 9:41 … 93 Applying an Exponential Function to Newton's Law of Cooling 60. Water in a water heater is originally Aa ← 122°F. The water heater is shut off and the water cools to the temperature of the surrounding air, which is 60°F. The water cools slowly because of the insulation inside the heater, and the value of k is measured as 0.00351. a. Write a function that models the temperature T (t) (in °F) of the water t hours after the water heater is shut off. b. What is the temperature of the water 12 hr after the heater is shut off? Round to the nearest degree. c. Dominic does not like to shower with water less than 115°F. If Dominic waits 24 hr. will the water still be warm enough for a shower?
