Answer:
Step-by-step explanation:
Given that 30% of all students who have to buy a text for a particular course want a new copy (the successes!), whereas the other 70% want a used copy.
Each purchaser is independent of the other and there are only two outcomes
X - no of persons who prefer new copies is Bin (15, 0.3)
a) E(x) = np =
Var(x) = npq =
Std dev (x) = 1.775
b)
c)
d) h(X) = revenue when x of 15 purchasers want new copies
E(h(x)) = 100(E(x) = 450
Here h(x) = 100x
Hence E(100x) = 100E(X)

- Since, 12² = 144 and 13² = 169, the square root of 150 is between 12 and 13.
- Then, you can pick any two whole numbers less than 13 and multiple them by 1/8.
- Remember that multiplying by 1/8 is the same that dividing by 8.
- Choose 12 and 11, for instance, and two rational numbers that are less than 1/8 of the actual side length are 12/8 and 11/8.
- 12/8 can be simplified to 3/2 and 11/8 is in its simplest form.
- Thus, two rational numbers that are within 1/8 of the actual side length of the bulletin board are 3/2 and 11/8.
