<span>A correlation
coefficient is a measure of the strength of dependence and correlation of a set
of data. It shows how good is the fitted model to the data. It will have values
ranging from -1.0 - 1.0. Having a coefficient that is the lower or the upper
limit will tell you that the model best fit the data and a good correlation.
However, as it goes farther from the limits then the correlation is to be a bad
one.</span>
Answer:
y=6x+20
Step-by-step explanation:
m= y2-y1/x2-x1
m= -4-8/-4-(-2)= 12/-2= 6/1
y= mx+b
y= 6x+b
8= 6(-2)+b
8=-12+b
+12 +12
b= 20
Step-by-step explanation:
1680 feet
Answer:
-In mathematics, the argument is a multi-valued function operating on the nonzero complex numbers. With complex number z visualized as a point in the complex plane, the argument of z is the angle between the positive real axis and the line joining the point to the origin, shown as φ in figure 1 and denoted arg z. To define a single-valued function, the principal value of the argument (sometimes denoted Arg z) is used. It is chosen to be the unique value of the argument that lies within the interval (–π, π].
