A small airline tracks weight and the external dimensions (height+length+width) of all bags they check. Some of their data is shown in the table below.
weight (lbs) 59 70 80 72 98
external dimensions (in.) 62 70 78 80 115
Which equation does not model the data in the table?
a) y=1.34x-20.78
b) y= .02x2-1.92x+ 104.92
c) y= .03x2+1.23x+107.81
d) y= 24.51(1.015)x
Solution
C is the equation which is not the model
it will give quadratic , and we will get linear as well but the model c is not possible
