the following measurements represent the wind chill as a function of the air speed(wind velocity) at an ambient temperature of 15 degrees F:
wind speed(x)
5,10,,15,20,25,30,35
wind chill T(degrees F)
7,3,0,-2,-4,-5,-7
a. fit a logarithmic equation model(y=a+b in x)
b. use your model to predict the wind chill temperature if the wind speed is 23(ambient T=15 degrees)
a. logarithmic model
a = 18.92076019
b = -7.09634239
x y a+b*ln(a)
577.65
1032.8
150-0.04
20-2-2.05
25-4-3.61
30-5-4.89
35-7-5.97
b. prediction
23-3.03
