Answer:
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:
For our case we have this:
n=2
And if we replace in the formula we got:
So then the we have perfect linear association. Because the heights and weights of the men are similar.
Answer:
122
Step-by-step explanation:
![x^6+y^2](https://tex.z-dn.net/?f=x%5E6%2By%5E2)
Plug in 1 for x and 11 for y
![=1^6+11^2](https://tex.z-dn.net/?f=%3D1%5E6%2B11%5E2)
1 to the power of any number will always equal 1
![=1+11^2\\=1+121\\=122](https://tex.z-dn.net/?f=%3D1%2B11%5E2%5C%5C%3D1%2B121%5C%5C%3D122)
I hope this helps!
