Anthropologists can estimate the height of a woman by measuring the length of her radius bone (from the wrist to the elbow). The
zloy xaker [14]
B = 0.26 h - 18.85,
where b is the length of the radius bone and h is the height.
To find the equation for height of a woman, you can solve the equation for h.
0.26 h = b + 18.85
h = ( b + 18.85 ) / 0.26
h = ( 100 b + 1,885 ) / 26
Then you can plug in the length of the radius bone in this equation.
