Question

the mean of 7 number is 13 if one number is excluded , the mean becouse 11 the excluded number is​

Answer 1

Answer:

25

Step-by-step explanation:

Mean = Adding all the numbers/the number of integers.

n + x + w + y + a + b+ q/7 = 13

13 x 7 = 91

The total of the 7 numbers ADDED together is 91.

If one number is excluded, the mean becomes 11.

7 - 1 = 6 numbers now.

6 x 11 = 66 (the total of the 6 numbers).

Difference: 91 - 66 = 25

The excluded number is 25.
