So we have a little red wagon that we'll call W. Then we ask, how many ears of corn can W carry?
We have an empty wagon; so W = 0 ears
We add one ear; now W = 1 ear
We add one more; now W = 1 ear + 1 more = 2 ears
We add yet another, W = 2 ears + another = 3 ears
And there you are. W is a variable; it's value varied (thus variable) from W = 0 through W = 3 ears. And we could add more or...gasp...even take some away from the wagon making W smaller.
Bottom line...a variable is just a symbol that can vary its value (like W did).

What is a factor usually being measured or observed that responds to another factor?
A factor that is usually measured or observed in response to another factor is called a dependent variable. In an experiment, the dependent variable reflects changes resulting from the manipulation of an independent variable. For example, in a study examining the effect of fertilizer on plant growth, the growth of the plants (dependent variable) is measured in response to the amount of fertilizer applied (independent variable).
What is control variable?
what is an controlled variable. we need to know it for our science proformance asscement!!! From a friend in need!
Independent and dependent variable?
Math: Independent variable is what you change. Dependent variable is what you measure.
What are the similarities between a control and a variable?
There are not any similarities between a control and a variable. However, a Control Variable, is a variable.
Why you use resistor with variable resistor?
Often we want to easily change a resistor value, so we use a variable resistor. For example, we may want to change the resistor that controls the power sent to a LED, so we can easily make it brighter or dimmer. Often if we use a variable resistor, there is only a very narrow range that is useful. Continuing our example, sometimes we use several LEDs, and we use the variable resistor to set them all to the same brightness. In this case, the resistance range that sets the LED to be twice as bright as the the other LEDs, and the resistance range that sends so much power to the LED that it is permanently destroyed is even less useful. So we add a fixed resistor in series with the variable resistor -- the fixed resistor sets the minimum net resistance, no matter how we turn the knob on the variable resistor. In our example, the addition of the fixed resistor allows us to turn the variable resistor throughout its whole range, and the LED gets brighter and dimmer; without that resistor, a certain range of the knob on the variable resistor would allow so much power to go to the LED that it would be destroyed.
What is variable and example of variable?
An variable in science something that can be changed and example is facts and figures .
Is temperature an example of continuous variable?
Yes. It is a continuous variable. As used in probability theory, it is an example of a continuous random variable.
Is the variable of x an example of abstract representation?

What Variable in algebra?
A variable in algebra is an unknown quantity as for example in the term 5y the variable is y
What is a non example of independent variable?
dependent variable
How do you write variable in a sentence?
Here is a example. "I wrote variable in a sentence."
What is the independent variable of a variable?
Just the number, for example: 7x the variable is 7. The variable is the number without the variable(x,y,z, etc.)
What id a variable?
A variable is a symbol the represents another number. Example: 2y - 5y Y is the variable.
How do you form a differential equation?
You write an equation that involves an independent variable (for example "x"), a dependent variable (for example "y"), and the first derivative, or higher-level derivatives, of the dependent variable (for example, dy/dx).
What is a example of controlled variable?
A controlled variable is a setting where the dependent variable is not controlled by the independent variable. For example, if you were trying to measure the rate of movement in an organism in highly salty concentrations, a controlled variable would include the organism in an environment with no salt at all.
Is insurance premiums for fire insurance an example of variable cost?

Can you provide an example of a non variable in this equation?
In the equation 2x 5 11, the number 5 is an example of a non-variable.
