The function H described 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 sholder) is X cm long. Predict the height of a woman whose humreus is 40 cm long is?

Question

The function H described 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 sholder) is X cm long.  Predict the height of a woman whose humreus is 40 cm long is?

shubhamsrg · Answer

what if i ask you value of 2x for x =4 ?

ash2326 · Answer

H(x)=2.75x+71.48
We need to find the height of a woman whose humreus is 40 cm
put x=40
$$H(40)=2.75\times 40+71.48$$
Can you solve the rest?

H=1.8558 @ash2326.  I tried to find the value of h.  Am I wrong?

ash2326 · Answer

You're right but you wouldn't get 1.8558. Check your calculations

anonymous · Answer

If I round it up then it would be 2?

ash2326 · Answer

$$2.75\times 40+71.48=110+71.48=181.48 cm$$
