Question

If the mean of 10 observation is 12 so what is their sum

Answer 1

Answer:

120

Step-by-step explanation:

MEAN=(SUM OF GIVEN OBSERVATIONS)/NO.OF OBSERVATIONS

     12  =  (SUM OF GIVEN OBSERVATIONS)/10

12*10  =  (SUM OF GIVEN OBSERVATIONS)

120     =  (SUM OF GIVEN OBSERVATIONS)

Answer 2

Answer:

Step-by-step explanation:

MEAN (GIVEN) = 12

NO. OF OBSERVATIONS (GIVEN) = 10

FORMULA FOR MEAN = SUM  OF OBSERVATION ÷ TOTAL NO. OF OBSERVATION

THEREFORE , 12 = SUM OF OBSERVATION ÷ 10

                       => SUM OF OBSERVATION = 12 × 10 = 120
