2m is the length so half is the radius

the radius is 1

so if c=2 $\pi$ 1

and $\pi$ 3.14159

u get 6.283

2(3.14159) x 1 = 6.283

Suppose the line of best fit is being found for some points that have an r-value of 0.769. If the standard deviation of the x-co

jeyben [28]

r value i.e Correlation between x value and y value = 0.769

$A_{x}$ =Standard deviation of the x-coordinate = 5.508

$A_{y}$ =Standard deviation of the y-coordinate = ?=k

Slope of line is given by formula

If slope of line is m, then

m = $r\times \frac{ A_{x}}{A _{y}}$

m= $0.769 \times \frac{k}{5.508}$

Substitute the value of k, i.e Standard deviation of the y-coordinate and then you can get the slope of line to three decimal places.

What is the solution to the following system of linear equations?

Lostsunrise [7]

x − 2y = −1 => x = 2y -1

2x + y = −12
2(2y - 1) + y = -12
4y - 2 + y = -12
5y = -10
y = -2
x = 2·(-2) - 1
x = -4 - 1
x = -5
