Given :

  • Given numbers are 6, 10, 0, 7, 9.

To Find :

  • The mean of the above data.

Calculation :

In order to calculate the mean, formula is given by,

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

 \dag Calculating the total sum of observations :

 : \implies \bf 6 + 10 + 0 + 7 + 9

On adding the numbers,

 : \implies{ \boxed{ \blue{\bf 32}}}

Therefore, sum of all observations (numbers) is 32.

 \star And, total number of observations is 5.

Now let's put the values in the equation,

  \dashrightarrow \bf Mean = \dfrac{ \not{32}}{ \not{5}} \\

On cancelling the numbers, we get,

 \dashrightarrow{ \underline{ \underline{ \boxed{\bf{Mean = 6.4}}}}}  \: \orange{ \bigstar}

Henceforth,

  • The mean of the given numbers is 6.4.

Given :

  • First four odd natural numbers which are 1, 3, 5, 7

To Find :

  • The mean of the above data.

Calculation :

In order to calculate the mean, formula is given by,

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

 \dag Calculating the total sum of observations :

 : \implies \bf 1 + 3 + 5 + 7

On adding the numbers,

 : \implies{ \boxed{ \blue{\bf 16}}}

Therefore, sum of all observations (numbers) is 16.

 \star And, total number of observations is 4.

Now, as per the formula, let's plug the values in the equation,

  \dashrightarrow \bf Mean = \dfrac{ \not{16}}{ \not{4}} \\

On cancelling the numbers, we get,

 \dashrightarrow{ \underline{ \underline{ \boxed{\bf{Mean = 4}}}}}  \: \orange{ \bigstar}

Therefore,

  • The mean of the given numbers is 4.

Given :

Given numbers are 6, 10, 0, 7, 9.

To Find :

The mean of the above data.

Calculation :

In order to calculate the mean, formula is given by,

Mean=

Numberofobservations

Sumofallobservations

Calculating the total sum of observations :

⟹6+10+0+7+9

On adding the numbers,

32

Therefore, sum of all observations (numbers) is 32.

\star⋆ And, total number of observations is 5.

Now let's put the values in the equation,

5

32

On cancelling the numbers, we get,

Mean=6.4

Henceforth,

The mean of the given numbers is 6.4.

Given :

First four odd natural numbers which are 1, 3, 5, 7

To Find :

The mean of the above data.

Calculation :

In order to calculate the mean, formula is given by,

Mean=

Numberofobservations

Sumofallobservations

Calculating the total sum of observations :

1 + 3 + 5 + 7:⟹1+3+5+7

On adding the numbers,

16

Therefore, sum of all observations (numbers) is 16.

⋆ And, total number of observations is 4.

Now, as per the formula, let's plug the values in the equation,

⇢Mean=

4

16

On cancelling the numbers, we get,

Mean=4

Therefore,

The mean of the given numbers is 4.
