Which of the following errors can be reduced only by increasing the sample size? a. systematic error b. random sampling error c.
garik1379 [7]

Answer:

The correct answer is

b. random sampling error

Step-by-step explanation:

Sampling is a statistical method of selecting a predefined number of observations  from a larger population to determine the characteristics of and to represent the larger population.

A sampling error is a type of error in statistics that is as  a result of a difference between the calculated statistical values of a selected sample and that of the entire population. A sample of a population with an error does not properly represent the statistics of the population.

By the definition of sampling in statistics, sampling error can be eliminated by Increasing the size of the sample taken from the larger population, analogous central limit theorem.

Given f(x) = 3x + 4 and g(x) = 8x + 1<br> then what is ( f + g )(0))?<br><br> *****HELP*^^^^^^
pochemuha

     •   f(x) = 3x + 4

     •   g(x) = 8x + 1


Sum both functions above:

     (f + g)(x) = f(x) + g(x)

     (f + g)(x) = (3x + 4) + (8x + 1)

     (f + g)(x) = 3x + 8x + 4 + 1

     (f + g)(x) = 11x + 5


Therefore,

     (f + g)(0) = 11 · 0 + 5

     (f + g)(0) = 0 + 5

     (f + g)(0) = 5   <———   this is the answer.


I hope this helps! =)

To convert a mixed fraction into an improper fraction:

a\frac{b}{c} =\frac{(a\cdot c)+b}{c}

49 \frac{1}{2} = \frac{(49\cdot 2)+1}{2} = \frac{98 +1}{2} = \boxed{\bf{\frac{99}{2}}}
