Total number present = 10

Sum of the numbers =?

Arithmetic mean = sum of the numbers / total number

Sum of the numbers = arithmetic mean x total number

Sum of the numbers = 5.6 x 10 = 56

Answer 2

Answer:

56

Step-by-step explanation:

Average mean = 5.6

No. Of scores = 10

Mean = sum of no./ number of scores

Therefore 5.6 = sum of no. /10

Cross multiply

Sum of no. = 5.6 x 10

= 56

The sum of the number is 56
