Question
Nate has the following data:9141792014312171419mIf the mean is 14, which number could m be?820Save answer
Solution
To find the value of 'm', we first need to understand that the mean is the sum of all numbers divided by the count of numbers.
Given that the mean is 14 and there are 9 numbers (including 'm'), we can set up the equation:
(9 + 14 + 17 + 9 + 20 + 14 + 3 + 12 + 17 + 14 + 19 + m) / 12 = 14
Solving the left side of the equation without 'm' gives us:
(149 + m) / 12 = 14
To isolate 'm', we multiply both sides by 12:
149 + m = 168
Subtracting 149 from both sides gives us:
m = 19
So, 'm' could be 19.
