Question 146593
{{{H(x)=2.75*x+71.48}}} Start with the given function.



{{{H(40)=2.75*(40)+71.48}}} Plug in {{{x=40}}} 



{{{H(40)=110+71.48}}} Multiply {{{2.75}}} and {{{40}}} to get {{{110}}}.  



{{{H(40)=181.48}}} Add {{{110}}} and {{{71.48}}} to get {{{181.48}}}.  



So the predicted height of a woman whose humerus is 40 cm long is 181.48 cm
