The function H descibed by H(X)=2.75X+71.48 can be used to predict the height, in centimeters, of a woman whose humerus (the bone from the elbow to the shoulder) is x cm long. Predict the height of a woman whose humerus is 39 cm long.
I have an answer of the height is 178.73 cm. Is that correct?

yes it looks right to me
Because all you needed to do is to plug in the value 39cm for x and calculate the answer, so u are correct.
