Question

find the data of the mean 17,25,28,35,40​

Answer 1

Correct Question :-

• Find the mean of the data :- 17, 25, 28, 35, 40.

Answer :-

• The mean of the given data = 29.

To find :-

• The mean of the given data.

Step-by-step explanation :-

• Let's find the mean of the given data!

We know that :-

$\underline{ \boxed{ \sf Mean = \dfrac{Sum \: of \: all \: observations}{Number \: of \: observations}}}$

Here,

• Sum of all the observations = 17 + 25 + 28 + 35 + 40.

• Number of observations = 5.

Hence,

$\rm Mean = \dfrac{17 + 25 + 28 + 35 + 40}{5}$

Adding all the numbers,

$\rm Mean = \cancel{\dfrac{145}{5}}$

Dividing 145 by 5,

$\overline{ \boxed{ \rm Mean = 29}}$

Therefore,

• Mean of the given data is 29.

Know more :-

What is mode?

• The observation which occurs maximum number of times in the given data is called mode of the data. In a grouped data, mode is the observation which has maximum frequency.

What is mean?

• The value obtained by dividing the sum of observations by the number of observations is called mean of the data.

Answer 2

Given data: 17, 25, 28, 35, 40

Need to find: Mean of the given data.
