Question

6) If the mean of 10 obseovation
is 12. What is their sum?​

Answer 1

Answer:

120

Step-by-step explanation:

$mean = \frac{sum \: of \: observation \: }{number \: of \: observation \: }$

12 = sum of observation / 10

sum of observation = 12 * 10

sum of observation = 120

Answer 2

Answer :

• Sum of their observations is 120

Given :

• The mean of 10 observations is 12

To find :

• Sum of observations

Solution :

Given

• Number of observations = 12
• Mean = 10

As we know that,

• Mean = sum of observations/no of observation

Where , Mean is 10 and Number of observations is 12

》Mean = sum of observations/no of observation

》Sum = Mean × no of observation

》 12 × 10

》120

Hence , Sum of their observations is 120
