Answer: Therefore, Option 'D' is correct.
Step-by-step explanation:
Since we have given that
Number of population = 132000
Number of voting districts = 11
According to question, no district is to have a population that is more than 10 percent greater than the population of any other district.
Let the number of population that the least populated district could have be 'x'.
So, it becomes,

Hence, there are 11000 population that the least populated district could have.
Therefore, Option 'D' is correct.
Answer:


Step-by-step explanation:
Given


Solving (a): The mean
This is calculated as:

So, we have:



Solving (b): The standard deviation
This is calculated as:

So, we have:




Let , a, b and c be the length of three sides of triangle, represented in terms of vectors as
.
Now, vector of same Magnitude acts as normal vector to each side.
So, equation of any vector p having normal q is given by

Now sum of three vector and it's normal is given as

Cross product of two identical vectors is Zero.
