Question

The mean of 10 numbers is 700. The sum 10 numbers is?

Answer 1

Answer:

7000

Step-by-step explanation:

mean=700

sum/10=700

sum=7000

Answer 2

The sum of 10 numbers is 7000 if the mean of the 10 numbers is 700.

Given,

Count of numbers, N = 10

Mean of numbers, M = 700

To Find,

Sum of numbers, S

Solution,

This problem could be solved using a very simple method.

We use the simple mathematical formula for finding the mean of a set of numbers to solve this problem.

The arithmetic mean, sometimes referred to as arithmetic average, is a measurement of a data set's central tendency; specifically, it is the sum of values divided by the total number of values. There are various mean types in mathematics, particularly in statistics.

Mathematically, arithmetic mean 'M' could be denoted as the following:

⇒ M = S/N

where 'S' is the sum of the values

and 'N' is the count of the values

Here we have been given the mean of a set of values, i.e., 'M' and 'N' are given. We have to find the value of 'S'.

For this, rearrange the equation for finding the arithmetic mean.

⇒ S = M × N

Substitute the values that we have in the above equation to get the sum of 10 numbers:

⇒ S = 10 × 700

⇒ S = 7000

Therefore, the sum of the values is 7000.
