Answer:
The answer is below
Step-by-step explanation:
The procedure of selecting a sample is thus called, fulfilling two fundamental properties:
-All individuals in the population have the same probability of being elected.
-All samples of the same size are equally likely.
From a mathematical point of view, simple random sampling is performed assuming that the population has infinite elements. In practice, it is often the case that the populations to be considered have a very large number of elements, which can be compared to a situation with infinite elements.
Yes, it is possible to sample data instances using a distribution different from the uniform distribution.
In excel, do the following to obtain a sample dataset.
E.g. to create a 5 element sample from the standard normal distribution, place the formula = NORM.S.INV (RAND ()) in cell A1, highlight the range A1: A15 and press Ctrl-D.
Answer: 1:10,000
Step-by-step explanation:
given data:
distance of the nearest star system = 100,000,000
distance to size ration of the sun earth system = 10,000
therefore;
100,000,000 / 10,000
= 10,000
The order of magnitude of the distance to size ratio of the Sun- Nearest Star system is about 1:10,000 times that of the Sun-Earth system.
The internal angles in a triangle add up to 180
I think the question should say
'2 angles in a triangle add up to 115 degrees'
so therefor
x+y+z=180
2 angles are x+y
115+z=180
z=3rd angle
solve
115+z=180
subtract 115 from boths ides
z=65
answer is third angle=65 degrees
