What else can I help you with?
When a researcher cannot tell which variable might be causing an observed effect in an experiment the variables are?
confounded
When should you use the addition property of equality to eliminate one variable in a system of equation?
When the coefficient of that variable, in which you want to eliminate, is negative.
When one variable increase while the other variable deacreases is a statement indicating an inverse relationship?
No. That condition is necessary but not sufficient.No. That condition is necessary but not sufficient.No. That condition is necessary but not sufficient.No. That condition is necessary but not sufficient.
The elimination method is useful when you can eliminate one of the variable terms from an equation by adding or subtracting another equation? true or false?
True. The elimination method is a technique used in solving systems of equations where you can eliminate one variable by adding or subtracting equations. This simplifies the system, allowing for easier solving of the remaining variable. It is particularly effective when the coefficients of one variable are opposites or can be made to be opposites.
What information is contained on the graphs y-axis?
Information about the variable that is plotted along that axis and an indication of the range of values of that variable which are of sufficient interest to be plotted.

Is it sufficient to do a signle experiment to test a hypothesis?
define a experimental variable
What is the purpose of the flag variable in a bubble sort?
to eliminate unnecessary swaps to eliminate unnecessary comparisons to stop as soon as the list is sorted to sort an array of unknown size

How do you solve systems of equations using linear combination?
You select the linear combination of the equations in such a way that at each stage you eliminate one variable.You select the linear combination of the equations in such a way that at each stage you eliminate one variable.You select the linear combination of the equations in such a way that at each stage you eliminate one variable.You select the linear combination of the equations in such a way that at each stage you eliminate one variable.
The elimination method is useful when you can eliminate one of the variable terms from an equation by adding or subtracting another equation?
True
What reduces an equation that has two variables to an equation that has one variable. It is then possible to find the solution for this variable.?
substitution
What variables did you have to control in order to get a valid result?
We controlled the independent variable (the variable we manipulated) to observe its effect on the dependent variable (the variable we measured). We also controlled for any potential confounding variables that could influence the results. Additionally, we ensured consistency in experimental conditions to eliminate any extraneous variables that could impact the outcome.
To eliminate the influence of uncontrolled variables during experimentation?
establish a control group identical to the experimental group except for the variable being tested
