Question

is the mean of the data 12,15,x,19,25 44 is 25 then x is​

Answer 1

Answer:

Data: 12,15,x,19,25 44

So, Mean= Sum of obsv./No. of obsv.

So, Mean= 115+x / 6

Since we know that the mean of the given numbers is 25.

Replacing 25 for Mean in the above equation, we get

25= 115+x / 6

=> x= 35 [Solving the equation]

So, x=35 (ans)

Answer 2

In context to question asked,

We have to determine the value of "x".

As per question,

it is given that,

Mean of the data 12,15,x,19,25 44 is 25

As we know that,

Mean of the data can be determined by adding all the values and dividing it by total number of values.

So, means of the given term will be,

$\frac{12+15+x+19+25+44}{6} \\=>\frac{115+x}{6}$

As per question,

The mean of the data is 25.

So, equating both the mean,

We will get,

$\frac{115+x}{6} = 25\\=>115+x = 25\times 6\\=>115+x = 150\\=>x = 150-115\\=>x = 35$

Hence, value of "x" will be 35.
