What shows the relationship between two variables?
A function expresses the relationship between two or more variables. A function can be expressed as a mathematical equation or as a graph. In general, a function expresses a the effect an independent variable has on the dependent variable..For example, in the classic linear function:y = mx + bx and y are the variables (m is said to be the slope, and b is the constant). This function expresses the mathematical relationship between the variables x and y. In this function, x is said to be the independent variable, and the function destines the y variable to be dependent upon the value of x.
Constant which multiples a variable in a term?
the co-efficient
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.
What is the relationship between flow rate and pipe size?
At constant pressure and constant fluid density, larger pipe results in larger flow rate.
What the relationship between temperation and pressuer in a gas?
Pressure is directly proportional to temperature therefore increasing one increases the other when volume is kept constant.
What is the relationship between a variable and a constant?
By definition:a variable varies (changes) in valuea constant is constant (fixed) in value
What relationship exists between two variable when their ratio is a constant?
Two variables whose ratio is constant have a linear relationship. The first variable is the second multiplied by the constant.
What is constant of variation in math terms?
It is a relationship between two variables such that one variable os always larger than the other by a multiple which is the constant of variation.It is a relationship between two variables such that one variable os always larger than the other by a multiple which is the constant of variation.It is a relationship between two variables such that one variable os always larger than the other by a multiple which is the constant of variation.It is a relationship between two variables such that one variable os always larger than the other by a multiple which is the constant of variation.
What has a variation in the relationship between two variable quantities with a constant ratio?
The relationship is a linear one. For example when driving at a constant speed, the relationship between distance driven and the time driven is linear with a constant ratio (of the constant speed).
What is a variation that is the relationship between two variable quantities with a constant ratio?
Direct variation.
What is the relationship Constant and variable?
It is a relationship of mutual exclusivity.
What is the relationship between two variable if the product of the variables is constant?
inversely proportional or inverse proportion
What are the dependent and independent variables in relationship between resistance and current at constant voltage?
dependent variable is current and independent variable is resisitance
What is the relationship in which the ratio of the manipulated variable an the responding variable are constant?
It is a direct [linear] proportionality.
How many types of correlation?
There are 3 types1.positive/ negative/zero/2.linear/non-linear3.simple/multiple/partial- If the direction is same,the relationship is positive-If the direction is opposite , the relationship is negative-If the amount of change is constant in different variable it is linear-If the amount of change is not constant in different variable is non- linear-If it is establishing a relationship between two characteristic then it is simple- If it is establishing a relationship between three or more characteristic then it is multiple-If it is establishing a relationship between only one of all the variable then it is partial
When would you use simple linear regression?
You use it when the relationship between the two variables of interest is linear. That is, if a constant change in one variable is expected to be accompanied by a constant [possibly different from the first variable] change in the other variable. Note that I used the phrase "accompanied by" rather than "caused by" or "results in". There is no need for a causal relationship between the variables. A simple linear regression may also be used after the original data have been transformed in such a way that the relationship between the transformed variables is linear.
Which variable is held constant when testing for the thermal expansion relationship of a gas?
pressure
