Respuesta :

Independent variable is the height and dependent variable is weight so you will have a quadratic such as weight = number•height^2 + number•height + number. All you need is to figure out first number and second number and third number (usually denoted by a,b,c) it will be a very tedious calculation by hand which deals with sum of the weight, sum of the weight squared, sum of weight•weight, number of weights, and sum of heights etc etc with the same pattern. It should be done by a calculator. At the end the Weight = a height^2 + b height + c (with a b c results displayed on the calculator) and then Answer = a*5.8^2 + b*5.8 + c

Weight of someone who is 5.8ft tall is 149.8 lbs.

What is a quadratic equation?

A quadratic equation is a method of representation of a unknown variable by some variable of degree upto 2.

How to find the weight?

a=5.607,b=-12.009,c=30.648

Let, y= weight(lbs) and x=height(ft)

y=5.61*x*x-12x+30.65

y=5.61*5.8*5.8-12*5.8+30.65

y=149.77

y≈149.8lbs.

Weight of someone having height 5.8ft tall is 149.8lbs.
