Accuracy vs precision
Naily [24]
Accuracy is how close a measured item is to the actual or true value and precision is how close the measured items are to being the same.  So you could weight 5 apples.  If each apple weights 2 lbs and you said that the 5 apples weight a total of 10lbs you are determining the precision.  Precision is independent of accuracy.  Accuracy would be if you put all 5 apples on the scale at one time and knew a exact amount.

What is the equation of a circle with its center at (0,-2) and passing through the point (3,-5)
Ksivusya [100]
Circle's Standard Form Equation:
r^{2} = (x - xo)^{2} + (y - yo)^{2}

First you need to substitute the C (0,-2) in the equation, where: Xo = 0 and Yo = -2;

r^{2} = (x - 0)^{2} + (y - ( -2))^{2} \\ r^{2} = x^{2} + (y + 2)^{2}

Now you substitute the Point (3,-5) values in the last expression, where: X = 3 and Y = -5;

r^{2} = 3^{2} + (( - 5) + 2)^{2} \\ r ^{2} = 9 + ( - 3)^{2} \\ r^{2} = 9 + 9 \\ {r}^{2} = 18

Now you get the R^2 value and substitute in the equation that you found putting the C values on it:

r^{2} = x^{2} + (y + 2)^{2} \\ x^{2} + (y + 2)^{2} = 18

Here is your standard form equation of the circle.
