Answer:
Variable A and variable B have a negative linear association.
Step-by-step explanation:
We are asked to find which best describes the association between variable A and variable B.
From the scatter plot we could clearly see that as the value of variable A are increasing the corresponding value of variable B is decreasing.
Also we could see that the points are linear.
Hence, the relationship that best describes variable A and variable B is:
Negative linear Association
Answer:
x = 3 and x = -7
Step-by-step explanation:
The given quadratic equation is 
. We need to find the solution of this equation.
If the equation is in the form of 
, then its solutions are given by :
Here, a = 1, b = 4 and c = -21
Plugging all the values in the value of x, such that :
So, the solutions of the quadratic equation are 3 and -7.
Here you go, The answer is 8.75
Well the answer options are a bit confusing but the steps are 1, 2, & 3.
