Answer:
The standard deviation of the distribution is 21.7 students.
Step-by-step explanation:
We are given the following in the question:
We treat college student living on campus as a success.
P(college student living on campus) = 0.38
Then the number of students follows a binomial distribution.
Sample size, n = 2000
We have to evaluate the standard deviation of the distribution.
Formula:
Putting values, we get,
Thus, the standard deviation of the distribution is 21.7 students.

What is liner equation with two variable?
- An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.
- For example, 10x+4y = 3 and -x+5y = 2 are linear equations in two variables.
-10x² -10y² = -300 ----a
5x² + 5y² = 150 ---- b
While trying to solve this,
We can multiply the eq. b by 2 so we will get eq. c and then add to eq. a we will get 0 as the solution.
10x² + 10y² = 300 ----c
-10x² -10y² = -300 ---a
<u>Everything cutoff, we will </u><u>get 0</u><u>, and there is no solution to these equations.</u>
