Question

Find the mean
of x+3,x+5,x+7,x+9and
x+11​

Answer 1

Step-by-step explanation:

Given :-

x+3,x+5,x+7,x+9 and x+11

To find:-

Find the mean of x+3,x+5,x+7,x+9 and x+11 ?

Solution:-

Given observations in the given data are:

x+3,x+5,x+7,x+9 and x+11

Sum of all observations

=x+3+x+5+x+7+x+9+x+11

=5x+35

Number of all observations = 5

We know that

Mean = Sum of all observations/Number of all observations

=> Mean = (5x+35)/5

=> Mean = 5(x+7)/5

=> Mean = x+7

Answer:-

The Mean for the given data is x+7

Used formula:-

• Mean = Sum of all observations/Number of all observations

Answer 2

Answer:

[(x+3)+(x+5)+(x+7)+(x+9)+(x+11)]÷5=[5x+35]÷5=x+7
