Select ALL the true statements about the scatter plot below.
N76 [4]

A scatter plot is a form of plot or mathematical diagram that displays values for two variables for a collection of data using Cartesian coordinates. The true statements are A, D, and E.

<h3>What is a scatter plot?</h3>

A scatter plot is a form of plot or mathematical diagram that displays values for two variables for a collection of data using Cartesian coordinates. One more variable can be presented if the points are programmed.

The following points about the scatter plot are true,

A. The graph shows a linear association

As there can be drawn a line between the two axes of the graph, and this line will give the approximate values, therefore, the graph shows a linear association. Thus, the statement is true.

B. The graph has no outliers

The graph has an outlier lying at the bottom right of the graph. Thus, the statement is False.

C. The graph shows a nonlinear association

As the graph has a linear association, it can not have a non-linear association. Thus, the statement is False.

D. The graph shows a positive association.

As the slope of the imaginary line is positive, the graph shows a positive association. Thus, the statement is true.

E. The graph could be used to show an association between the hours worked and the amount earned.

The above situation can be depicted by the given graph. Thus, the statement is true.

Full steps and all reasons, thanks!​

You can focus on the two sub-triangles ABC and ACD

We know that they are both right triangles, because we're given that AC and BD are perpendicular.

The sides AB and AD are the hypothenuses of these triangles, so we know their length through the pythagorean theorem:

AD^2 = AC^2+CD^2

AB^2 = AC^2+BC^2

But since we're given BC=CD, the expressions for AD and AB are actually the same expression. This proves that AD=AB, and thus that the triangle is isosceles.
