The function F described by ​F(x)equals=2.75xplus+71.48 can be used to estimate the​ height, in​ centimeters, of a woman whose h
Kryger [21]

Answer:

156.5375 cm

Step-by-step explanation:

The function used to estimate the height is F(x)

F(x) = 2.75x + 71.48

The humerus is xcm long. When x = 30.93cm, we put x = 30.93 into the function F(x)

F(30.93) = 2.75(30.93) + 71.48

= 85.0575 + 71.48

= 156.5375 cm(4 decimal places)
