Respuesta :
When finding the mean you should first add up all the numbers which are 12,2,8,6 and 57 which will give you a sum of 85 next you should divide your sum by how many numbers there are which is 5 and your answer should be 17
Answer is 17.
Explanation;
Mean = sum of the value / number of values
To find out the sum of the values you have to add together all given numbers.
Hence,
sum of the values = 12 + 2 + 8 + 6 + 57
= 85
Number of values means number of data that we have.
According to the given data, there are 5 numbers.
Hence,
mean = 85 / 5
= 17
