What else can I help you with?
What exists if the y-coordinates decrease as the x-coordinates increase?
A negative correlation
What exists is the y-coordinates decrease and the x-coordinates increase?
Example: draw the graph where y = 10 - x , from x = 0 to 5 step 1
Is y equals 9 divided by x a proportional relationship?
Yes. It is inversely proportional. An increase in x results in a proportional decrease in y and vice versa.
Do the y-values increase drcrease or stay the same as the x-value increases?
The behavior of the y-values as the x-values increase depends on the specific relationship between the two variables. If the relationship is positive, the y-values will increase as the x-values increase. If the relationship is negative, the y-values will decrease. In some cases, the y-values may remain constant regardless of changes in the x-values.
How does the value of y change as the x value increase?
The change in the value of ( y ) as ( x ) increases depends on the relationship between the two variables. If ( y ) is a function of ( x ) that is increasing, then ( y ) will also increase as ( x ) increases. Conversely, if the relationship is decreasing, ( y ) will decrease as ( x ) increases. In cases where the relationship is non-linear or involves complex interactions, ( y ) may change in a more variable manner.
If the coefficient of determination is 0.81 the coefficient of correlation?
Given co-efficient of determination, r2 = 0.81. co-efficient of correlation, r = square root of 0.81 = +0.9, if the data have move in the same direction.(Let x and y as variables then x and y have linear relationship and x increase or decrease and y also have increase or decrease) = -0.9, if the data have move in the opposite direction.(Let x and y as variables then x and y have linear relationship and x decrease or increase and y is also increase or decrease)
How do you find percent increase and decrease?
If you start with a value x and end with a value y thenPercentage change = 100*(y/x - 1)If y > x then the above is positive and is a percentage increase andif y < x then the above is negative and is a percentage decrease.
What does a positive correlation between variables x and y imply?
It implies that an increase in x is accompanied by an increase in y. And similarly, they decrease together.
What is a direct proportion?
Two quantities x and y are said to be in direct proportion if whenever the value of x increase (or decrease), then the value of y increases (or decrease) in such a way that the ratio x/y remains constant.
What exists if the y-coordinates decrease as the x-coordinates increase?
A negative correlation
In an inverse relationship how do the values of y change as the values of x increase?
Y would decrease in value as X increases in value.
When the y- value increase as the x-value decrease how can it be shown in a table?
By finding the differences between the x and y columns on the table.
What exists is the y-coordinates decrease and the x-coordinates increase?
Example: draw the graph where y = 10 - x , from x = 0 to 5 step 1
Is y equals 9 divided by x a proportional relationship?
Yes. It is inversely proportional. An increase in x results in a proportional decrease in y and vice versa.
How are direct variations different from inverse variations?
Consider two variables x and y. If x varies directly as y then y = cx where c is some constant of variation. This means that whenever x increases, y increases and it increases by c times as much as the increase in x. Also, if x decreases, then y decreases by c times the decrease in x. If x varies inversely as y then y = k/x where k is some constant of variation. This means that whenever x increases, y decreases and it decreases by k times as much as the increase in x. Also, if x decreases, then y increases by k times the decrease in x.
How does the value of y change as the x value increase?
The change in the value of ( y ) as ( x ) increases depends on the relationship between the two variables. If ( y ) is a function of ( x ) that is increasing, then ( y ) will also increase as ( x ) increases. Conversely, if the relationship is decreasing, ( y ) will decrease as ( x ) increases. In cases where the relationship is non-linear or involves complex interactions, ( y ) may change in a more variable manner.
What is increasing and decreasing function?
To increase something means to make it bigger, and to decrease something means to make it smaller. These are used often with numerical values (numbers), e.g. I increased (made bigger) 20 to 30. Here I am increasing by 10, etc.
