A researcher carefully calculates the correlation coefficient and gets a value of r=1.23. What does this value mean? A mistake was made.

The variables have a weak, positive relationship

The variables have a strong positive relationship

The variables have a strong negative relationship

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

the two may have that, even a breakdown is probably offered
