What is an Example of two independent variables?
Variables are symbols that replace unknown numbers. Variables are often letters. For example: 5*x=10 7*6=y Here "x" and "y" are the variables.
What does independent mean in science?
Scientifically, independent refers to the direct opposite of dependant. The dependant variable is varied deliberately and systematically by the experimenter, and the summary of the independent variables form the results of the experiment. Example: Experiment to determine tensile strength of lumber. Method: Add 10kg weights to sample lumber and observe results (dependant variable is number of 10 kg weights) Results: 1...2...3...4...5...6CRASH 'CRASH' = Independent variable, proving tensile strength > 60kg (dependant variable)
What do dependent and independent variables represent in science?
In science, independent variables are variables that you control the change of, to see how somethings changes as a result of changing these variables. Dependent variables are variables that change because the independent variables are changed, but you don't change directly. A good example of this would be an experiment where you're measing how cold a glass of water gets after putting in different amounts of ice in it and wating 5 minutes. The independant variable would be the amount of ice you put into each glass, because that's what you're directly changing. The dependent variable is how cold each glass gets, because that's the result you're trying to see by changing the independent variable - it changes because something else changes. Additionally, when graphing, independent variables are put on the x-axis (horizontal line), and dependent variables are put on the y-axis (vertical line).
-2x plus y equals -3?
-5
What is the 3 solutions to the equation y equals -4x-5?
You need two independent equations to solve for two unknowns or variables (x and y).
Does the way the equal sign is used change which variables are dependent and independent?
No, but take for example the equation { y=x^2 +5 } y is dependent on x and x is independent, nothing you do to it, rearrange whatever will change the fact that x is independent and y is dependent
How do you solve 4x-y equals 5?
-1
What is the solution of x plus y equals 5?
You have two unknown variables, x and y. You therefore need at least two independent equations to find a solution.
How many variables do you test within one experiment?
Generally speaking, you only want to test a single variable within one experiment so when a change occurs you know what caused it. If you change multiple variables at once it is harder to attribute the change to a single cause.
What is the average weight for a 5' child?
Many variables must be considered when determining your average weight, depending on your age (pre-teen, teen, adult), frame size (small-medium or large bone), genetics and the height, in general it's around 85 lbs. - 100 lbs.
Is anova qualitative or quantitative?
! ANOVA is generally computed for two or more QUANTITATIVE variables. If the quantitative variables are two or less in number, people prefer the t test (one sample t, paired t, or independent samples t) The Independent variable however is qualitative( for example, Girls and boys or Names of Schools.) It is the dependent variable that is Quantitative (for example, the ages - 2, 5 , 70, etc or weight or number of somethings). If you have 2 independent variables, you go for the two way ANOVA. Else, it's the one way ANOVA. !
Average weight if 5 ft. 5?
Many variables must be considered when determining your average weight, depending on your age (pre-teen, teen, adult), frame size (small-medium or large bone), genetics and the height, in general it's around (male) 122 - 150 lbs., (female) 113 - 138 lbs.
