Question

compare the number of swimmers at city pool and the outside temperature to make an interpolation. what is the best estimate for the number of swimmers when the outside temperature is 75°f? 15 swimmers 20 swimmers 25 swimmers 30 swimmers

Explanation:

Step1: Locate the temperature on the x - axis

Locate \(75^{\circ}F\) on the x - axis (temperature axis).

Step2: Find the corresponding value on the y - axis

Move vertically from \(75^{\circ}F\) on the x - axis to the line of best fit. Then move horizontally to the y - axis (number of swimmers axis).

Answer:

30 swimmers
