The complete question in the attached figure N 1
we know that
The formula for Sample Standard Deviation is indicated in the attached figure N2
n in this problem is 4 <span>and Yuri had to divide in the formula by 3 </span>
therefore
the answer is Yuri divided by n instead of n -1
Answer:
each person would get 4 with 4 left over
Step-by-step explanation:
Given that the total number of swimmers is 80, and the ratio of the seventh grade swimmers to all swimmers is 5:16. You will know that answer for this through cross multiplication. So let's put it this way:
5 ?
-- ----
16 80
Multiply 80 by 5 and you get 400 then divide this by 16 and you get 25.
Therefore, out of 80 swimmers, there are 25 seventh grade swimmers. Hope this answer helps.
