What does X-Y equal in algebra?
It equels 10* * * * *The answer depends on the values of x and y.
When the values for x increases faster than the values for y which way will the graph curve away from or toward the y axis?
On an x-y graph, the line y=x is a diagonal from bottom left to top right when x and y increase at the same rate. If values of x increase faster than values of y, then the line would curve away from the y-axis.
How can you tell from a scatter plot whether 2 variables have a positive correlation a negative correlation or no correlation?
Suppose the scatter plot is of a variable X on the horizontal scale and Y on the vertical scale.Find the approximate middle of the x values and call it p.Find the approximate middle of the y values and call it q.Draw horizontal and vertical lines through the point with coordinates (p, q).If you know about quadrants, skip this paragraph. The two lines through the point (p,q) divide up the plane into 4 quadrants. Quadrant I is top right. Quadrant II is top left. Quadrant III is bottom left. Quadrant IV is bottom right.If the scatter plot is mostly in quadrants I and III the correlation is positive. If mostly in quadrants II and IV the correlation is negative. Otherwise the correlation is small.Remember, though, that 0 correlation does not mean no relation. y = x2 will have 0 correlation but it is a perfectly well defined relationship!Suppose the scatter plot is of a variable X on the horizontal scale and Y on the vertical scale.Find the approximate middle of the x values and call it p.Find the approximate middle of the y values and call it q.Draw horizontal and vertical lines through the point with coordinates (p, q).If you know about quadrants, skip this paragraph.

How do you find where two lines intersect based on an equation?
when the x and y values of both equations are equal, because the point of intersection will only have one x value and one y value
Why is y the dependent variable?
Traditionally y is a function of x and hence it is dependent. Graphically as well various values of x result in corresponding values of y; showing the dependence of y on x.
Suppose the scatterplot of log y on x produces a correlation close to 1 then will the difference between consecutive values of y for equal x-intervals be approximately constant?
No. The ratio of consecutive values of y for equal x-intervals will be approx constant.
What is implied when it is said that x and y have a positive correlation?
When it is said that x and y have a positive correlation, it implies that as the value of x increases, the value of y tends to increase as well. This relationship suggests that there is a direct association between the two variables, meaning that higher values of one are associated with higher values of the other. Positive correlation can be quantified using a correlation coefficient, typically ranging from 0 to 1, where values closer to 1 indicate a stronger correlation.
Write a c program that will exchange the values of x and y after the statement executed x is equal to y and y is equal to x?

What is the pattern of the x and y values?
To determine the pattern of the x and y values, one would typically look for relationships such as linearity, proportionality, or trends in the data points. For example, if the x values increase consistently and the y values also show a corresponding increase, it may indicate a positive correlation. Alternatively, if the y values decrease as x values increase, this could suggest a negative correlation. Identifying specific mathematical relationships, such as linear equations or quadratic functions, would also help clarify the pattern.
When is the standard correlation coefficient positive?
Assume that you are correlating two variables x and y. If there is an increasing relationship between x and y, (that is , the graph of y=a+bx, slopes upward), the correlation coefficient is positive. Similarly, if there is a decreasing relationship, the correlation coefficient is negative. The correlation coefficient can assume values only between -1 and 1.
When is the correlation coefficient closest to 1?
When x and y values of points agree in a linear relationship
What is the formula of correlation coefficient of correlation?
ρx,y=cov(x,y)/sqrt[Var(x)*Var(y)]
What values do x and y have if x16 y16 and when x and y are combined they equal 0?
If ( x = 16 ) and ( y = -16 ), then their combination ( x + y = 0 ) holds true. Thus, the values of ( x ) and ( y ) are 16 and -16, respectively.
What is the domain and range of the sine function y is equal to 2 sin x?
Domain (input or 'x' values): -∞ < x < ∞.Range (output or 'y' values): -2 ≤ y ≤ 2.
What does the product of 3yx equal?
That depends on the values of x and y.
