Write a short statement that expresses a possible relationship between the variables. (size of file, time to download the file)

Here we got as variables the size of a file and the time needed to download that file. So the size is the independent variable and the time is the dependent variable. (because the time will depend on the size of the file).

A relationship between these two can be of the form:

The time needed to download a file is proportional to the size of the file.

This can be written as : T(w) = A*w

where T is time, w is the weight of the file and A is a proportionality constant.

no this is a nonlinear negative

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
