If they increase or decrease exactly, then the constant of proportionality or coefficient of proportionality. If not exactly, then a correlation coefficient.

How does a direct variation look?
Two variables, x and y are said to be in direct variation with one another if they are related by an equation of the form y = cx where c (>0) is the constant of [direct] variation. In the coordinate plane, this equation gives rise to a straight line, through the origin, and with a gradient (slope) = c. What this means that both x and y are 0 together, and that every increase (or decrease) in x results in an increase (decrease) of c times that amount in y.
How do you increase 29 by 30?
Add them together which equals 59
What is the similarities between correlation analysis and regression analysis?
Correlation analysis seeks to establish whether or not two variables are correlated. That is to say, whether an increase in one is accompanied by either an increase (or decrease) in the other most of the time. It is a measure of the degree to which they change together. Regression analysis goes further and seeks to measure the extent of the change. Using statistical techniques, a regression line is fitted to the observations and this line is the best measure of how changes in one variable affect the other variable. Although the first of these variables is frequently called an independent or even explanatory variable, and the second is called a dependent variable, the existence of regression does not imply a causal relationship.
What is the relationship between the legs and the hypotenuse?
The two legs squared and added together = the length of the hypotenuse's length squared
What is the average decrease of 9.66 to 6.25 6.41 to 1.45 and 4.29 to 3.66?
The differences are 3.41, 4.96 and 0.63, which when added together give 9 and an average of 3.
The relationship between two quantites that increase or decrease together is called?
Variation in direct proportion.
What is the relationship between two quantities that increase or decrease together?
Direct variation
What is the relationship between two data sets when their data values increase or decrease together?
It is a positive relationship.
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.
The relationship between two quantities that increase or decrease together is called?
direct variation or positive correlation.
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.
Can the removing of energy increase the volume of a substance because the molecules come closer together?
No. It can increase the volume in some cases, but not BECAUSE the molecules come closer together. If the molecules come closer together, the volume will DECREASE.
When two variables increase or decrease together in the same ratio they?
Are in direct proportion
Does the surface energy increase or decrease with increase in planar density?
The surface energy decreases with an increase in planar density. This is because a higher planar density means more atoms are closely packed together, leading to a decrease in the number of surface atoms and therefore a decrease in surface energy.
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.
How do you increase and decrease frictional force?
To increase frictional force, you can increase the roughness of the surfaces in contact, increase the normal force pressing the surfaces together, or increase the coefficient of friction by using materials that interact with more resistance. To decrease frictional force, you can use lubricants to reduce surface interaction, decrease the normal force, or use smoother materials to reduce resistance.
