The predicted speed for a hailstone with a diameter of 5 inches is 153 miles per hour.
We can substitute d=5 into the equation and solve for s:
s = 7.62 + 29.6(5)
s = 7.62 + 148
s = 155.62
Rounding to the nearest whole number, we get s = 153.
A meteorologist has collected the data about the diameter of hailstones in inches, d, and the speed at which they fall in miles per hour, s. The resulting line of best fit for the data set is s=7.62+29.6d. What is the predicted speed for a hailstone with a diameter of 5 inches? Round to the nearest whole number.(1 point)
