the independant variable is the one that you can change/control, e.g. time\nThe dependant variable is the one that changes outside of your control. e.g. distance travelled. \nOn a graph you plot the independant variable on the x-axis and the dependant on the y-axis

Yes you can. For example education is a dependent variable on  number of schools, teachers, students, etc., which are independent variables. You can relate any two of these independent variables and explain education status in an area. This can be extended to any thing that you can collect data on (sales, incomes, etc.).

people are not here to do your homework:\n\nThis is the definition of a function:\nA variable y is a function of x if a relation between x and y produces exactly one value of y for each value of x.\n\nread it carefully, the answer to your question is quite obvious

An example: Boyle's law: pV = constant\nYou choose the volume V (the independent variable)\nWhen you change the volume, the pressure p changes by it: the dependent variable.\npV = constant is only true for constant T, so now the temperature must be the controlled variable; it must be constant.\n\nTh

You have said that they aren't independent; however, you have no mention of how they depend on each other. Therefore there is no way to calculate the answer.\nIf they *were* independent, then E[X*Y] = E[X]*E[Y]. Each one is an exponential distribution with lambda = 1, so the mean is just 1 (could also integrate e^(-x) from 0 to infinity, you also get 1.)

Sorry to say, you better pass on this data set.  \n\nNote that each row of numbers totals 100, as these are percentages, so the variables are correlated, and have limited application.\n\nI think your professor wants two of the variables to be somewhat independent, meaning one is not a function of the other.  Such as gas mileage and price, for example, if you had a list of automobile makes.\n\nRatio variables are those in which the ratio of two of the numbers have meaning, such as miles per gallon, for example.  If car A gets 15 mpg and car B gets 20 mpg, you can take the ratio of the two: 15/20 and compute 0.75, meaning car A gets 75% of the mileage of car B.

OH NOES THIS IS LIKE A MATH PROBLEM!!!! i can't handle any more variables :( sry.\n\n\nhahahaha.

If y is a function of x, then for every value of x there is one, and only one, value for y.  Y is the dependent variable in this case.

An independent variable is the variable that does not depend on anything, like time.  \n\nThe dependent variable depends on the independent variable.\n\nHere is an example... You want to measure how irritated you get from being around your little brother as a function of time.  Time passes, regardless or your irritability.  But the more time passes, your irritability changes.  So your irritability is dependent on the independent factor of time.\n\nThe control is something that you use to measure experimental values by.  Suppose you are not sure that it is your brother making you irritable... maybe you just become irritable because you are part of the experiment.  So, one day, we measure your irritability as a function of time without your brother.  This is the control.  That way when we measure your irritability with your brother around, we can see how these two differed.\n\nFinally, the constant is something that doesn't change.  Maybe your brother is twice as irritable as your sister.  In this case, irritability is being multiplied by a constant.  Maybe ritalin makes your brother less iritable by a constant amount.  Maybe simply being in the room with your brother, even while he is sleeping, increases your irritability by a certain, constant, amount.

A linear equation in two variables describes a relationship in which the value of one of the variables depends on the value of the other variable. In a linear equation in x and y, x is called x is the independent variable and y depends on it. We call y the dependent variable. If the variables have other names, yet do have a dependent relationship, the independent variable is plotted along the horizontal axis. Most linear equations are functions (that is, for every value of x, there is only one corresponding value of y). When you assign a value to the independent variable, x, you can compute the value of the dependent variable, y. You can then plot the points named by each (x,y) pair on a coordinate grid. The real importance of emphasizing graphing linear equations with your students, is that they should already know that any two points determine a line, so finding many pairs of values that satisfy a linear equation is easy: Find two pairs of values and draw a line through the points they describe. All other points on the line will provide values for x and y that satisfy the equation.\n\n\nA linear equation is special because: \n-It has one or two variables. \n-No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction. \n-When you find pairs of values that make the linear equation true and plot those pairs on a coordinate grid, all of the points for any one equation lie on the same line. Linear equations graph as straight lines.

property AND it's more relaible. (if something happens to it you're not at loss, you have insurance)\n\nstocks=== they can go down in value, or the corporation can fail: ie enron.\n\nmutual funds===as reliable as stocks, income is never certain, and the chance of loss is there.

Yes, independent goes on x axis and dependent on y axis.\nIndependent is producing dependent and x-y has same connotation.

there is direct and indirect variation, direct is y=kx and indirect is xy=k or y=k/x.  the constant of varitaion is k, which determines what x and y are.  normally they will tell you x or y and k, and ask you to find the other variable.

The dependent variable is Y\nThe independent variable is X
