In the Special Right Triangle below, solve for the value of y. Y = _____ (keep your answer in simplest radical form)
pishuonlain [190]

Answer:

Value of Y = 5√2 units

Step-by-step explanation:

Given:

Perpendicular = X

Base = Y

Hypotenuse = 10

Find:

Value of Y

Computation:

Cos θ = Base / Hypotenuse

Cos 45 = Y / 10

1/√2 = Y / 10

Value of Y = 5√2 units

Which of the following is an advantage of using systematic random sampling?
bekas [8.4K]

This is a question that asks about the advantages of a systematic random sampling. Thus, we first take a look at the types of sampling, and then we see the advantage of systematic random sampling.

Samples may be classified as:

Convenient: Sample drawn from a conveniently available pool.

Random: Basically, put all the options into a hat and drawn some of them.

Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.

Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.

Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.

Systematic:

One of the bigger advantages is that the systematic sampling eliminate clusters, which means that the last option is wrong.

Inadvertently missing patterns is a problem in systematic sampling, and not an advantage, thus the third option is also wrong.

It also does not reduce sampling variability, thus the first option is wrong.

From this, it can be concluded that the correct option is:

Systematic random sampling does not require a finite population size.
