Answer:

Using reflexive property (for side), and the transversals of the parallel lines, we can prove the two triangles are congruent.

Step-by-step explanation:

Since AB and DC are parallel and AC is intersecting in the middle, you can make out two pairs of alternate interior angles<em>.</em> These angle pairs are congruent because of the alternate interior angles theorem. The two pairs of congruent angles are: ∠DAC ≅ ∠BCA, and ∠BAC ≅ ∠DCA.
With the reflexive property, we know side AC ≅ AC.
Using Angle-Side-Angle theorem, we can prove ΔABC ≅ ΔCDA.

If the correlation between two variables is close to 0, you can conclude that a scatterplot would show

andrew-mc [135]

Answer:

The correct option is (c).

Step-by-step explanation:

Correlation coefficient is a measure of the strength of the linear relationship between two variables.

It ranges from -1.0 to 1.0.

A correlation coefficient closer to 1.0 indicates that there is a strong positive linear relation between the variables.

A correlation coefficient closer to -1.0 indicates that there is a strong negative linear relation between the variables.

A correlation coefficient closer to 0 indicates that there is no linear relation between the variables. But some other form of relation might exist.

If the correlation between two variables is close to 0, we can conclude that a scatter plot would show no straight-line pattern, but there might be a strong pattern of another form.

Thus, the correct option is (c).
