<span>1.6. The Pearson Correlation Coefficient, otherwise known as r-value, must have a value between -1 and 1. It's used to measure how closely related two different variables are. -1 means negative linear correlation, 0 means no linear correlation, and 1 means positive linear correlation.</span>
Answer:
rhombus
Step-by-step explanation:
A rhombus had EQUAL four sides yet no right angles. Why not trapezoid? Well, a trapezoid doesn't have four equal sides. Square and rectangle aren't the answer because they contain right angles. Hopes this helps!
I already a seed you when you asked this the first time. The answer is 3.
You multiply both sides by 50 and then you get this
(In the picture)
Straight line:
y = mx + c
m is the slope of the graph and c is the y-intercept
In this case, m = 5 as stated in the question, so...
y = 5x + c
By substituting the given co-ordinates (-2,-1) into this equation, we can find c
-1 = 5(-2) + c
-1 = -10 + c
-1 + 10 = -10 + c + 10 (Add 10 to both sides)
9 = c
c = 9
Put c = 9 into the equation:
y = 5x + 9
