Answer: The true statements are:-
There are about the same number of points above the x-axis as below it.
The points are randomly scattered with no clear pattern.
The number of points is equal to those in the scatter plot.
Explanation:
- A residual plot is a graph which shows that the residuals on the vertical axis and the independent variable on the horizontal axis.
Thus, the number of points is equal to those in the scatter plot and ame number of points above the x-axis as below it.
We know the points are randomly scattered across the plot, so that there is no relationship. Thus the points are randomly scattered with no clear pattern.
5,004,000,002,008 That's standard
The answer is 0.01 seconds it would take for five seconds
To answer this, we need to start with the standard equation for an ellipse:
(x^2/a^2)+(y^2/b^2)=1
Where a is one half of one axis, and b is one half of the other.
The problem states that one axis is 1057 ft, and the other is 880 ft, so divide these values by 2 and square them. This results in:
(x^2/279,312.25)+(y^2/193,600)=1
For verification, if you have a graphing calculator, solve for y, set the size of the window so it should perfectly fit the ellipse, and check (it does)
