Question

The mean of 1,2,x,3and 4 is 2 find value ofx

Answer 1

Answer:

0

Step-by-step explanation:

we know that

sum of observation / number of observation = mean

therefore

$\frac{1 + 2 + x + 3 + 4}{5} = 2 \\ 10 + x = 10 \\ x = 0$

Answer 2

Answer:

To find the value of x, we can use the information that the mean of 1, 2, x, 3, and 4 is 2. The mean, or average, of a set of numbers is found by adding all the numbers together and dividing by the number of digits in the set.

Step-by-step explanation:

Mathematically, the mean (M) of a set of n numbers is represented by

M = (sum of numbers) / n

Given that the mean of the numbers is 2, we can set up the following equation:

(1 + 2 + x + 3 + 4) / 5 = 2

We can simplify this equation by adding the known numbers on both sides:

(1 + 2 + 3 + 4) / 5 + x/5 = 2

On the left-hand side of the equation, we have the mean of the known numbers: (1 + 2 + 3 + 4) / 5 = 10/5 = 2.

So the equation becomes:

2 + x/5 = 2

We can then solve for x by subtracting 2 from both sides:

x/5 = 0

And then multiply both sides by 5 to get the value of x:

x = 0

Therefore, the value of x is 0.
