Simple random selection involves a selection where all the elements in the dataset have the same chance of being selected.

The selected names are:

<em>Engler, Motola, Redmond and Zenkel</em>

We have:

n =32 --- All names

r = 4 ---- Sample to select

There are several ways to select a sample of 4 using a simple random sample. Some ways are:

  • <em>Select any 4</em>
  • <em>List all names in even position and select the first 4</em>
  • <em>List all names in position divide by 4 and select any 4 that is divided by 8</em>
  • <em>List all names in odd position and select the first 4 that can be divided by 3</em>
  • <em>Etc</em>

<em />

Going by the third method, the selected positions are:

4, 8, 12, 16, 20, 24, 28 and 32

Select 4 positions that can be divided by 8

8, 16, 24 and 32

So, the selected names are:

<em>Engler, Motola, Redmond and Zenkel</em>

If A+B+C=<img src="https://tex.z-dn.net/?f=%5Cpi" id="TexFormula1" title="\pi" alt="\pi" align="absmiddle" class="latex-formula"
seraphim [82]

Answer:

a + b + c = \pi \\  =  > c=  \pi - a - b \\  <  =  >  \tan(c)  =  \tan(\pi - a - b)  =  -\tan(a + b)

Step-by-step explanation:

we have:

\tan(a)  +  \tan(b)  +  \tan(c)  \\  =  \tan(a)  +  \tan(b)  -  \tan(a + b)  \\  =  \tan( a)  +  \tan(b)  -  \frac{ \tan(a) +  \tan(b)  }{1 -  \tan(a)  \tan(b) }  \\  =  \frac{ ( \tan(a) +  \tan(b)  ) \tan(a) \tan(b)  }{ \tan(a) \tan(b)  - 1 } (1)

we also have:

\tan(a)  \tan(b)  \tan(c)  \\  =  -  \tan(a)  \tan(b)  \tan(a + b)  \\  =  \frac{ -(\tan( a  )   + \tan(b) ) \tan(a)  \tan(b) }{1 -  \tan(a)  \tan(b) }  \\  =  \frac{( \tan(a)  +  \tan(b)) \tan(a)   \tan(b) }{ \tan(a) \tan(b)  - 1 } (2)

from (1)(2) => proven
