Calculate the mean 12,2,8,6,57

Answers

Answer 1

Answer:

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

Answer 2

Answer: 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

How do you find the slope of a line?

Answers

-- Pick any small piece of the line.

-- From the left end to the right end of that piece, measure
how much the line rises or drops.

-- Measure how much horizontal distance that piece covers.

-- Divide the amount of rise or drop by the horizontal distance.
That number is the slope of the line.

-- If the line drops as it goes from left to right, then the slope is negative.
