What is a variable used for in Python?
A variable is used to store information. As an example say you are asking someone for their favorite food, and want to store the answer in a variable called favoriteFood: favoriteFood = input("What is your favorite food?") Now if you print the value of favoriteFood (using print(FavoriteFood)) you will see that it has been saved in that variable. You can store any type in a variable, such as number, a string, or even an object.
What is the function of a variable resister in an electrical circuit?
A variable resistor usually has three terminals, one of which is connected to the 'wiper' by which means its resistance is measured. By using all three terminals, we can control the potential difference in a circuit. When used in this way, we call the variable resistor a 'potentiometer'. By using two of the three terminals, one of which must be connected to the variable wiper, we can control the current passing through circuit. When used in this way, we call the variable resistor a 'rheostat'.
What is the advantage of static character variable?
Static variables exist for the entire duration of the program. Therefore a static character variable is a character that exists for the entire duration the program is running. Regardless of where a static variable is declared and initialised, it is physically instantiated and initialised when the program loads. If the variable has function scope, whatever value is currently assigned to the variable will remain in effect the next time that function is called, but only the function can modify the variable. If the variable has class scope, then the variable exists even if no instances of the class have yet been instantiated, but any and all instances share the variable (it is common to the class, not to any one instance of the class). Static class variables must be initialised outwith the class body and outwith any other function body, but can only be modified by the class members (both static and non-static) and by friends of the class. If the variable has file scope, then the variable is a global variable. Global variables are largely frowned upon as there's no way to control what code can modify the value. Passing local function variables to other functions is the preferred method as this gives much greater control over which code can access and/or modify the value, as well as limiting the lifetime of the variable. To ensure the variable exists throughout a program's lifetime (as per a static variable), instantiate the variable from within the program's entry point.
Why do local variables lose their values between calls to the function in which they are defined?
They are designed to work that way - and it's actually quite useful to have variables that work that way. If you want to keep a value from one method call to the next, you have to use some other way to store the information. For example, you can store information in an object field.
How to convert a string into an integer in javascript?
In C# you can do that in the following way Convert.ToInt32(yourStringHere), for instance Convert.ToInt32("wikianswers"). But not all string can be converted to int type. If it happens compilator will throw the exception converting error which you can handle using structure try { ...//your code } catch (Exception) { ... //your code in the case of the exception }
Is tables always the best way of finding the value of a variable?
false
Compared to diagrams and equations are tables always the best way of finding the value of a variable?
No, tables are not ALWAYS the best way to find a value. They may be the easiest way or not.
Are tables one of the best ways of finding the value of a variable?
They can be, but not always. Other methods (equations, graphs) may be the best way.
What is useful for finding ones way and is a three letter word?
Map
In what way can we use variables?
A variable is used purely for the purpose of storing a single value. Being variable, the value can be changed at any time. A constant is the opposite of a variable; its value cannot be changed.
What is a depened variable?
The key word here is 𝘥𝘦𝘱𝘦𝘯𝘥𝘦𝘯𝘵. This means that the variable's value depends upon something else. For example, to figure out Y, you need to multiply 4 times X and then add 3. Whatever value you put for X determines what Y's value will be. So Y depends upon the value of X . That makes Y a dependent variable.
Why is it useful to rewrite a formula in terms of another variable?
to be more clear and not mix up your work. i suggest this all the way.
Does it matter which way you subtract the values when you are finding the distance?
Not if you take the absolute value of the answer.
Write down a PHP code to add a session variable?
The preferred way is to simply alter the session superglobal. <?php $_SESSION['variable'] = "value"; ?>
How is a box and whisker plot useful?

What are the definition between indeoendent and dependent variables?
The independent variable determines the value of other variables and is change by the person doing the experiment. The dependent variable is what is affected by the independent variable; it "depends" on the independent variable.
What is the independent varible?
a variable that is function is the value of other variables! And your mom. No this answer is wrong. Its the way you eat pizza.
