Answer:

0.2

Step-by-step explanation:

Probability = Number of favorable outcomes / Number of posssible

outcomes

There are 5 favorable outcomes ( the 25-20 = 5 people not from his neighborhood).

There are 25 possible outcomes ( the 25 total contacts).

P (call a person not from his neighborhood) = \frac{5}{25} = 0.2

svetoff [14.1K]

Using sampling concepts, one sample of 5 high schools in the city of Chicago is given by:

Brooks,  Hyde Park, Young Womens, Marshall, Noble - UIC.

<h3>What is the missing information?</h3>

The problem is incomplete, but researching it on a search engine, it gives us a list of 15 high schools in Chicago, and asks us to take a sample of 5.

<h3>What is population and sample?</h3>

  • Population: Collection or set of individuals or objects or events whose properties will be studied.
  • Sample: The sample is a subset of the population, and a well chosen sample, that is, a representative sample will contain most of the information about the population parameter. A representative sample means that all groups of the population are inserted into the sample.

Hence, from the concepts of sample and populations, the sample of 5 means that we have to select 5 schools from the 15 listed, hence one possible option is given by:

Brooks,  Hyde Park, Young Womens, Marshall, Noble - UIC.

Simplify the difference.
mr_godi [17]

\displaystyle\frac{n^2-10n+24}{n^2-13n+42}-\frac{9}{n-7}=\frac{(n-6)(n-4)}{(n-6)(n-7)}-\frac{9}{n-7}\\\\=\frac{n-4}{n-7}-\frac{9}{n-7}=\frac{n-4-9}{n-7}\\\\=\frac{n-13}{n-7}

The last choice is appropriate.
