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.
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.
What values are plotted on the y-axis of a graph?
In general, y-axis values are the values that depend on the x-axis values.
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
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.
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 a program x and y
What does x y equal?
It equels 10* * * * *The answer depends on the values of x and y.
What does X-Y equal in algebra?
It equels 10* * * * *The answer depends on the values of x and y.
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 does the product of 3yx equal?
That depends on the values of x and y.
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.
When two variables are correlated there are four possible explanations of the correlation What are they?
a. The correlation between X and Y is spurious b. X is the cause of Y c. Y is the cause of X d. A third variable is the cause of the correlation between X and Y
If y tends to increase as x increases on a scatter plot what is the correlation of the paired data?
If Y increases as X increases, you are referring to a positive correlation. However, if Y falls as X increses, you have a negative correlation.
What is x y3 and y9 as an ordered pair?
The answer depends on the values of x and y. The answer depends on the values of x and y. The answer depends on the values of x and y. The answer depends on the values of x and y.
