Hey there!
• When you hear the word “mean” in mathematics it usually defined as “average”.
• To find it you have to ADD all of the numbers DIVIDE all of the numbers you have in the given data plot.
YOUR EQUATION:
10 + 8 + 5 + 12 + 20 / 5
= 18 + 5 + 12 + 20 / 5
= 23 + 12 + 20 / 5
= 35 + 20 / 5
= 55 / 5
= 11
Therefore, your answer is: 11
Good luck on your assignment & enjoy your day!
