The The square root of R² (the coefficient of determination) is not r, the correlation coefficient. Therefore, it's false.
<h3>What is a correlation coefficient?</h3>
It should be noted that the correlation coefficient is used to measure how string the relationship between two variables are.
The correlation formula tells us the linear relationship between the variables. R² is the square of the correlation coefficient.

Answer:
The value of polynomial for x = 2 that is f(2) will be 32
Step-by-step explanation:
We have given polynomial
We have to find the value of f(2)
We have to find the value of polynomial for x = 2
So for finding this value we have to just put x = 2 in polynomial
So f(2) will be
So the value of polynomial for x = 2 will be 32
Answer:
15 meters
Step-by-step explanation:
The diagram of the problem is attached below in the first image.
Chords KM and LN (which is the diameter) intersect at X.
Theorem: If the diameter is perpendicular to a chord, it bisects the chord.
Therefore:
LN divides KM into equal parts of 6 meters,
Applying the theorem of intersecting chords:
KX*XM = LX*XN
6*6=3*XN
3*XN=36
XN=12
Next, we find the length of the diameter LN
LN=LX+XN
=3+12
=15 meters
The diameter of the completed circle is 15 meters.
Answer:
- x-intercept (12.5, 0)
- y-intercept (0, -5)
Step-by-step explanation:
The slope of the line is ...
... (change in y)/(change in x) = (-3 -(-5))/(5 - 0) = 2/5
The y-intercept is given: (0, -5).
The slope-intercept form of the equation can be written from this information as ...
... y = (2/5)x - 5
Solving this for y=0 (to find the x-intercept), we have
... 0 = (2/5)x - 5
... 5 = (2/5)x
... 5·(5/2) = x = 12.5
So, the x-intercept is 12.5, and the y-intercept (given) is -5.
