The gauge of an extension cord measures the diameter (thickness) of the wires inside. The maximum rates

Question:

The gauge of an extension cord measures the diameter (thickness) of the wires inside. The maximum rates (in amperes) at which electric current can safely flow through 16-gauge extension cords are shown in Table 73 for various lengths of cords. Not following these guidelines can cause a fire from overheating.

Let A be the maximum number of amperes that can be safely delivered by a 16-gauge extension cord that is L feet long.
a. Identify the explanatory and response variables.
b. Which variable should be described by the horizontal axis of a coordinate system? How about the vertical axis?
c. Construct a scatterplot.
d. Is the association positive, negative, or neither? What does that mean in this situation?
e. A Milwaukee Screw driver Power Unit® requires 6.5 amperes. Select all the lengths of 16-gauge extension cords shown in Table 73 that can be safely used with the screwdriver.
