Answer:

Step-by-step explanation:

The correlation coefficient, r value, measures the strength and direction of 2 variables in a scatterplot. It ranges from +1 to -1.

+1 means a perfect positive correlation

-1 means a perfect negative correlation

0 means there is no correlation

Also,

a value close to 0.7 would signify a strong relationship (whether positive or negative)

a value close to 0.5 indicates a moderate relationship

a value close to 0.3 indicates a weak relationship

Now, the question says the r value is 0.315

THis is POSITIVE

Also, this is a "weak" relationship

Thus, we can say:

It has weak correlation, or answer choice D

D is right.

Blank 1: Given

Blank 2 : AD is parallel to BC

Blank 3: <3≅<2

Blank 4: Transitive property of convergence

Blank 5: Definition of Bisect

Step-by-step explanation:

We need to fill in the blanks from the given options.

Blank 1:

ABCD is a parallelogram

This is given

So, blank 1: Given

Blank 2:

A parallelogram have parallel sides i.e in the given parallelogram AD is parallel to BC and AB is parallel to DC

So, Blank 2 : AD is parallel to BC

Blank 3:

We are given <3≅<2

So, Blank 3: <3≅<2

Blank 4:

We know, <1≅<3 and <3≅<2 using transitive property (A≅B and B≅C then A≅C)

So, <1 ≅ <2 is due to transitive property of convergence

Blank 4: Transitive property of convergence

Blank 5:

DC bisects <ADE

A bisect is an line or angle that divides into exactly two parts.

So, Blank 5: Definition of Bisect
