When thinking about rotational symmetry, you must remember that rotational symmetry means if you are given a figure, and you turn the figure, you end up with the same figure. This happens when you have regular polygons, and each angle is congruent. In order to find the angle of rotation, you divide 360 by the number of angle you are given. if you rotated 360 degrees, that means 360/360=11. Your figure only had one angle, so it can't even be a polynomial! Also, every figure in the world will look exactly like it started if rotated 360 degrees, so this would not be logical.

I wish to determine the correlation between the height (in inches) and weight (in pounds) of 21-year-old males. To do this, I me
Serga [27]

Answer:

r=\frac{2(23146)-(139)(333)}{\sqrt{[2(9661) -(139)^2][2(55457) -(333)^2]}}=1

So then the we have perfect linear association.  Because the heights and weights of the men are similar.

Step-by-step explanation:

Let X represent the Height and Y the weigth

We have the follwoing dataset:

X: 70, 69

Y: 169, 164

n=2

The correlation coefficient is a "statistical measure that calculates the strength of the relationship between the relative movements of two variables". It's denoted by r and its always between -1 and 1.  

And in order to calculate the correlation coefficient we can use this formula:  

r=\frac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{[n\sum x^2 -(\sum x)^2][n\sum y^2 -(\sum y)^2]}}  

For our case we have this:  

n=2 \sum x = 139, \sum y = 333, \sum xy = 23146, \sum x^2 =9661, \sum y^2 =55457  

And if we replace in the formula we got:

r=\frac{2(23146)-(139)(333)}{\sqrt{[2(9661) -(139)^2][2(55457) -(333)^2]}}=1

So then the we have perfect linear association.  Because the heights and weights of the men are similar.
