Question

the avg of 30 no.s is 0. of them at the most how many may be greater than zero?​

Answer 1

Answer:

29

Step-by-step explanation:

since average is zero, we know that sum of all the 30 no.s will also be zero.

So, we can have a condition that sum of 29 no.s is x and 30th no. is -x

Hence, avg=sum of 30 no.s/30

= sum of 29 no.s+30th no./3

=x+(-x)/30

=0
