Standard deviation is equal to the square root of the variance. To arrive at this work out the mean, then subtract the mean and square the result of each number. Then work out the mean of those squared differences and take the square root of that.
when you subtract one square number with another the answer is 16 what are the two numbers
The number subtracted is 16 (42). The other square number is 25 (52). *If you include zero, the pair 9 (32) and 0 (02) also fits the equation.
9, the square of 3, and 4, the square of 2

You want to create an equation for this. The equation should look like this: x^2 - 2x + 4 = 0 Use the quadratic equation to solve it.

There aren't any whole numbers that satisfy this.

So the problem is: Solve: 4x2 - x = 3
The result :)
The roots are 4 and 5. If you subtract the square number 16 (4X4) from the square number 25 (5X5), you would get 9.
4 and 9
9, the square of 3, and 4, the square of 2
5 and 2
