When you add the values 3, 5, 8, 12 and 20 and then divide by the number of values, the result is 9.6 This is called the mean, or the average. 9.5 is called "the mistake."
The answer will depend on the country (or region) whose currency the question is about. Different countries have coins of different values. For example, the US has a 25 cent coin but not a 20 while the Eurozone has 20 cents but not 25.The answer will depend on the country (or region) whose currency the question is about.

Interval is the values between 20 - 29; so 23 is within the 20-29 range.
It means the difference between the lowest and highest values E.G 100 - 80=20, so the range is 20.
To solve the equation y = x^2 - 3x - 20 using systems, you can set up a system of equations by substituting y with x^2 - 3x - 20. This gives you the equation x^2 - 3x - 20 = 0. You can then solve this quadratic equation using factoring, the quadratic formula, or completing the square to find the values of x. Once you have the values of x, you can substitute them back into the original equation to find the corresponding values of y.
