From:

3.15--------------4 metres in 300 seconds--------------->3.20

The beetle covered a distance of 4 metres in the space of 5 minutes, which is 5*60 seconds. 5*60 seconds is in fact: 300 seconds.

So the beetle was moving at a very slow speed of (1/75) metres per second.

<em>Distance covered = s = 4 meters</em>
<em>Time taken = t = 5 minutes = 4 X 60 = 240 seconds</em>

<em>Speed = s / t = 4 / 240 </em>
<em>             = 0.01667 m/s Answer</em>

18n squared + 57n -10
aniked [119]
Most people use the decomposition method but i dont know how to do that so i use the Joes method a method similar to decomp. but easier.
canadian way

Find gcf: None
complet trinomial: 18n^2+57-10
find the product=10(18)
                       =-180
find the sum     =57
-3 and 60 goes into both meaning if you multiply 3 and60 you get -180 and if you add them you get 57.

so (n-3)(n+60)
divide by a in this case it 18
so (n<u>-3</u>)(n+<u>60</u>)
       18     18
do not divide. treat it like a fraction so you reduce it to lowest terms
(n<u>-3</u>)(n<u>-3)
</u>   18   10
<u /> at this point its reduced to lowest terms so now you take the deniminator and move it beside the "n"

=(18n-3)(10n-3)

therefore your answer is (18n-3)(10n-3)
I hoped this helped :)

The difference between the sample statistic and population parameter is called:_______
myrzilka [38]

Answer:

The difference between the sample statistic and population parameter is called sampling error.

Step-by-step explanation:

We are given the following in the question:

  • A sample is a part of population, it is a subset of population.
  • A sample statistic describes the sample. It is a characteristic of sample and different from the population.
  • A parameter describes the population. It is characteristic of a population.
  • A sample may not be able to represent the whole population and this may lead to error.
  • Thus, sampling error is the difference between the sample statistic and population parameter.
  • It arises when the sample is not able to describe the population.

The difference between the sample statistic and population parameter is called sampling error.
