<h3>Answer:</h3>
- A — 1
- B — ∑[k=0..2] 15Ck(.24^k)(.76^(15-k))
- D — 12 and 3.1
- A — 0.1091
- B — 0.83 ...
<h3>Explanation:</h3>
1. The probability is 0.52 that the officer will pull over a driver and then the expected number more. So, if x is the expected number of drivers pulled over until one is not texting, we have ...
... x = 0.52(1+x)
... 0.48x = 0.52
... x = 0.52/0.48 = 13/12 = 1 1/12 ≈ 1 . . . . matches selection A
(<em>Comment on this result</em>: I find it interesting that these are the odds in favor of finding a driver who texts. That is, if the probability of texting is 0.98, the odds are 49:1 that a driver will be texting, and the expected number of pull-overs is 49.)
2. The probability of at most 2 being cured is the probability of 0, 1, or 2 being cured. You need to add up those probabilities. The sum in answer selection B does that.
3. The mean of a binomial distribution is ...
... μx = np = 60·0.2 = 12
... σx = √(np(1-p)) = √(12·0.8) ≈ 3.0984
These match selection D.
4. 20C14(0.8^14)(0.2^6) = 38760·.043980·0.000064 ≈ 0.109100 . . . matches A
5. mean(x) = 0.94; mean(x^2) = 1.58, so ...
... σx = √(1.58 -0.94²) ≈ 0.83 . . . . matches selection B
The least-cost theory is better used to tell more about site locations for manufacturing companies than for service-industry corporations because industrial locations are said to be often selected using the presence of natural resources.
<h3>What is site selection?</h3>
Site selection is known to be the ways that are used in looking at or examining different options and seeing their advantages and disadvantages.
Note that Site selection is one that emanated from the needs assessment that has been made. The presence or availability of natural resources is a factor used by local site-selection.

<span>Answer:
It was written in the question the following:
static public char ch = // wrong!
The word "public" must come before "static", and since this is not the case here, the above statement is NOT a legal declaration of a class variable.
public static char ch =; //</span>
