The correlation coefficient between the variables are always between +1 and -1
If the correlation coefficient is near to +1 the degree of relationship between variables is strongly positively correlated. And if the correlation coefficient is near to -1 the degree of relationship between variables is strongly negatively correlated.
Hence at the extremes +1 and -1, there is a strong degree of relationship between two variables
Near to 0 (the middle of the range), there is a weak degree of relationship between two variables
So, the answer would the value the is nearest to 0 since we want a weak relationship
The value that is nearest to 0 is a) 0.10
So, the answer is a)0.10
For
reading the fraction like f(x)/h only (f(x+h) start fraction f(x) / h end fraction), the answer is 
They are alike because you are just doubling the number by 2
The tip would be $17.26
All you have to do is multiply 86.29 x .2 (20%)
ANSWER
72 square feet
EXPLANATION
The perimeter of a rectangle is given by:
P= 2l+2w
It was given that, the perimeter of the rectangular mat, is 36 feet.
36= 2l+2w
Divide through by 2.

It was given also that, the length of the mat is twice its width.
This implies that,

Put equation (2) into equation (1) to get,



This means that the length is 12 ft.
The area of the rectangular mat is
