it means that there are two numbers that are not constant. the value of each number is always related to the other based on an internal function/formual. those two vairables are usually related through a 3rd constant
For example, look at surface of a rectangle that is 100 square meters.
its length might be 10, and its width ten
or its length might be 20, and its width 5
the length and width are vairables (changing), but they are related in a way that they always produce the same constant (surface).
This is TRUE by the way and don't doubt this answer. This Example is very precise.
What else can I help you with?
What does a line graph related to?
It is related to the two variables that are plotted in the line graph.It is related to the two variables that are plotted in the line graph.It is related to the two variables that are plotted in the line graph.It is related to the two variables that are plotted in the line graph.
What is the measure of how strongly two variables are related to one another?
correlation
What does a correlation coefficient of 0.8 mean?
It means that there is a strong positive association between changes in the two variables being studied. Positive association means that the two variables tend to increase together or decrease together. Note that there is no mention of a causal relationship between the variables.
How are line graphs used to show how two variables are related?
i searched this and got nothing so... srry try something else please
Will the sum of two normally distributed random variables be normally distributed if the random variables are independent?
Yes, and the new distribution has a mean equal to the sum of the means of the two distribution and a variance equal to the sum of the variances of the two distributions. The proof of this is found in Probability and Statistics by DeGroot, Third Edition, page 275.
