Step-by-step explanation: If your correlation coefficient is positive, that means that your slope which is how steep the line is or your line of best fit must also be positive.

Remember that the correlation coefficient is just a number that indicates the direction and closeness of points of a line of best fit.

If it has a correlation coefficient of 0.89, the points would be close together but not very very close.

What is the solution of x=2+ sqrt x-2

wariber [46]

Answer:

Step-by-step explanation:

$x=2+\sqrt{x-2} \\\\x-2=\sqrt{x-2} \\\\(x-2)^2=\pm(x-2) \\\\x^2-4x+4=\pm(x-2) \\\\$

$x^2-5x+6=0$ OR $x^2+3x+2=0$

x=2 and 3

Hope this helps!
