Commutative property:- x + 2 = 2 + x
distributive property:- 2x - 2 = 2(x - 1)
Answer:
The strong linear relationships are:
r = 0.95
r=-0.83
Step-by-step explanation:
When we have points whit apparent linear tents, we can fit the curve to a line and when the correlation coefficient (r) is equal to 1, we have perfect correlation and when r is equal to 0 we do not have a correlation.
Therefore r = 0.95 suggest strong linear relationships.
Now, we can use the same analysis with a negative value of r, so r = -0.83 is strong too.
I hope it helps you!
I believe the perimeter is 232. Since it's a regular polygon that means all the sides are equal so you take the two expressions on the sides of the polygon and set them equal to each other. Now you know that x=22 so you take that value and substitute it into one of the expressions to get the side length (x+7➡️22+7=29) now we know that each side length is 29. Since there are 8 sides you multiply 29 by 8 and get 232. Hope this helped!
