A certain city with a population is ti be divide into 11 voting districts and no district is to have a population that is more than q0 percent grater than the population of any other district, what is the minimum possible population that the least populated district could have?
10700 10800 10900 11000 11100
for a finite sequence of nonzero numbers, the number of variations in sign is defined as the number of pairs if consecutive terms of the sequence for which the product of the two consecutive is negative. Which is the number of variation in sign for the sequence 1, -3,2,5,-4,-6?
One
two
three
four
five .
if n and y are positive integers and 450y =n^3, which of the following must be an integer?
1)y/3*2^2*5
2)y/3^2*2*5
3)y/ 3*2*5^2

是3吗？
是的话就是（1，-3）（-3，2）（5，-4）
3.if n and y are positive integers and 450y =n^3, which of the following must be an integer?
1)y/3*2^2*5
2)y/3^2*2*5
3)y/ 3*2*5^2
450Y=N^3=3^2*2*5^2 带进去可以化简吧

想问下有没有漏条件？感觉是不是要告诉一共多少人啊？
就这个还真不懂算耶~
牛牛们来吧~
楼主你那个第一题少条件的，没告诉总人数怎么可能知道least的人数，最least么就是1.。。。
这个题目好像是prep里有的
The 1st question missed one condition: the sum of the population is 132,000.
because we need "the minimum possible population that the least populated district", so
set it as x, and the rest as 1.1x, therefore, we have:
x+10*1.1x=132000 => x=11,000
It is a Q in Prep~
