The height and weight of several adults were recorded: Using this model, what would be the weight of someone who is 5.8 ft tall? Round your answer to the nearest tenth. You must find the quadratic regression equation first.

Subtracting is the opposite of adding

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
