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.
Answer:
Step-by-step explanation:
Helena Violet Kaneesha
1b 1b 1b
x pairs x pairs x pairs
Helena 1b + x pairs of socks
Helena = 1 b(baseball) + $7X ( X is the number of pairs of socks)
Helena ----- $5 + 7X
Since all 3 bought the same thing, multiply the above by 3
answer = 3(5 +7x)
or Distribute
Answer = (3*5) + (3*7x)
