Mean: To find mean you do the same as you would to find an average. Add up all of the numbers and divide by how many numbers are there. So, 8.3 + 4.5 + 6.2 + 9.6 + 4.3 + 11.2 + 5.9 + 9.7 + 10.5 = 70.2 Then divide by 9 since you have 9 numbers. 70.2 / 9 = 7.8
Median: To find median you set up the data from least to greatest and cross out one number from each side until you are left with one number as the middle number. 4.3, 4.5, 5.9, 6.2, 8.3, 9.6, 9.7, 10.5, 11.2 4.5, 5.9, 6.2, 8.3, 9.6, 9.7, 10.5 5.9, 6.2, 8.3, 9.6, 9.7 6.2, 8.3, 9.6 = 8.3 Mode: Mode is the most, meaning the number that appears the most in your set of data. In this case there is no mode because in your set there is no number that occurs more than once.
It would be the negative form of those bumbers and the non-negative form of those numbers. The absolute value applies to negative numbers the same. For example absolute value of -3 is 3.
<h3>How to solve an equation with one variable</h3>
Herein we have an equation with several rational constants and only one variable, x, which has to be cleared by using algebra procedures. The procedure is shown below:
2 · x + 1 / 3 + x - 1 / 4 = 13 / 2 Given
2 · x + x = 13 / 2 - 1 / 3 - 1 / 4 Compatibility with addition / Existence of additive inverse / Modulative property
3 · x = 71 / 12 Definitions of addition and subtraction / Distributive property
x = 71 / 36 Compatibility with multiplication / Existence of multiplicative inverse / Modulative property / Result
