Question

I need assistance with this problem. It is confusing. I am thinking it is the first answer

Answer 1

Step 1

Given;

`s(L)=0.118L-25`

Required; To find the independent and dependent quantities in the relationship.

Step 2

An independent variable is a variable that represents a quantity that is being manipulated in an experiment. x is often the variable used to represent the independent variable in an equation. Notice that as L the length of the shoe changes it affects s(L), the size of the shoe. The independent variable is not affected by the dependent variable. From this the question the independent quantity is;

`L,\text{ the length of the shoe in mm}`

A dependent variable represents a quantity whose value depends on how the independent variable is manipulated. y is often the variable used to represent the dependent variable in an equation. For this question, the dependent quantity is;

`s(L),\text{ the size of the shoe}`

Answer;
