What else can I help you with?
The relationship between two quantities that increase or decrease together is called?
direct variation or positive correlation.
When one variable increases the other does what?
The other can increase, decrease or stay the same. It depends on the relationship between the two variables.
In an arithmetic sequence the constant rate of increase or decreas between successive terms is called the?
An arithmetic sequence does not have a constant rate of increase or decrease between successive terms, so it cannot be called anything!The constant increase or decrease is called the common difference.
What does the slope of a trend line tell you about the relationship between two quantities?
If the slope of the trend line between variables X and Y is m, then an increase in value of 1 unit in X is associated with an increase of m units in the value of Y. The relationship is one of association, not of cause-and-effect.
A correlation of -0.90 between two sets of test scores indicates that?
There is quite a high degree of linear agreement between the two variables with one showing an increase when the other shows a decrease.
What is the relationship between two quantities that increase or decrease together?
Direct variation
The relationship between two quantites that increase or decrease together is called?
Variation in direct proportion.
What is the relationship between two quantites that increase or decrease together called?
If they increase or decrease exactly, then the constant of proportionality or coefficient of proportionality. If not exactly, then a correlation coefficient.
The relationship between two quantities that increase or decrease together is called what?
The relationship between two quantities that increase or decrease together is called a positive correlation. This means that as one quantity increases, the other quantity also increases, and vice versa.
What is the relationship between hardness and ductility?
when ductility increase hardness decrease
The relationship between two quantities that increase or decrease together is called?
direct variation or positive correlation.
What are some ways to describe the relationship between sets of numbers?
by their increase or decrease
What is Graph the relationship between cost and number?
They are inverly related ,number increase cost decrease as wellas cost increase may qulity & number decrease
What can be said about the relationship between and immediately after an increase in temperature?
Immediately after an increase in temperature, the relationship between two variables may change. This change could result in an increase, decrease, or no change in their relationship, depending on the specific properties of the variables involved.
How will a pressure increase affect a gaseous system?
An increase in pressure will cause the gas molecules to be compressed closer together, which will increase the frequency of collisions between molecules. This can lead to an increase in temperature and a decrease in volume of the gas.
4 kinds of relationships between the physical quantities?
Direct relationship: When two quantities increase or decrease together. Inverse relationship: When one quantity increases while the other decreases. Linear relationship: When the relationship between the quantities can be represented by a straight line. Nonlinear relationship: When the relationship between the quantities cannot be represented by a straight line.
What does a correlation coefficient of 0.8 mean?
It means that there is a strong positive association between changes in the two variables being studied. Positive association means that the two variables tend to increase together or decrease together. Note that there is no mention of a causal relationship between the variables.
