Answer:

Sample

Step-by-step explanation:

The term that represents the description in the question is called sample.

Take for instance:

  • 40 students selected from a class of 100
  • 1000 people selected from a population of 100000

In the above descriptions:

40 and 1000 represent the samples while 100 and 100000 represent the populations, respectively.

Another example is when 10 cats are picked from an animal farm in order to study their eating pattern.

All these and many more represent sample.

Log k-log(k-2)=log25
Studentka2010 [4]

Answer:

k = \frac{25}{12}

Step-by-step explanation:

Using the rules of logarithms

log x - log y = log(\frac{x}{y} )

log a = log b ⇒ a = b

Given

logk - log(k - 2) = log25, then

log (\frac{k}{k-2} ) = log25, thus

\frac{k}{k-2} = 25 ( multiply both sides by (k - 2)

25(k - 2) = k

25k - 50 = k ( subtract k from both sides )

24k - 50 = 0 ( add 50 to both sides )

24k = 50 ( divide both sides by 24 )

k = \frac{50}{24} = \frac{25}{12}
