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
Answer:
x = 3 and 7
There are two true solutions.
Step-by-step explanation:
To solve 
, use inverse operations by squaring both sides of the equal sign.
The quadratic expression can be factored into binomials and set equal to 0 by the zero product property to find x.
(x - 3) ( x - 7) = 0
x-3 = 0 so x=3
x-7 = 0 so x=7
Now check each solution into the original equation to be sure it solve the solution and is not extraneous.
and
![3-7 = \sqrt{-4(3)+28}\\[tex]-4 = \sqrt{16}\\-4 =-4](https://tex.z-dn.net/?f=3-7%20%3D%20%5Csqrt%7B-4%283%29%2B28%7D%5C%5C%5Btex%5D-4%20%3D%20%5Csqrt%7B16%7D%5C%5C-4%20%3D-4)

36 cups ........................................
Make each adult x and each kid 5x
and
set equal to 14.
so it would be
3.5x=14.
14/3.5 = 4
so
x = 4.
adult tickets are 4$ while kids are 2$
