Question

find the mean of the first 10 negative integers from 0​

Answer 1

Answer:

$mean \: = \: \frac{ - 1 -2 - 3 -4 - 5 - 6 - 7 - 8 - 9 - 10 }{10} \\ = \frac{ -55 }{10} = - 5.5$

Answer 2

Answer:

the first 10 non negative even integers are from 0 to 18 . the average of those integers is (0+18/) 2=18/2=9. thus , the sum of those integers is 9×10 =90

sum of first 10 negative integers is

= -55 .
