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.

Find the angle of elevation if the building is 653 feet tall and the observer is 150 feet from the building. Round to the neares
natita [175]

Answer:

Angle of elevation = 77.1°

Step-by-step explanation:

The formula to solve for angle if elevation is given below as:

tan θ = Opposite/ Adjacent

Where

Opposite = Height of the building = 653 ft

Adjacent = Distance from the building = 150 ft

θ = Angle of Elevation = ?

Hence:

tan θ = 653ft/150ft

θ = arc tan (653ft/150ft)

= 77.063069956°

Approximately to the nearest tenth = 77.1°
