Answer:

The method for selecting a stratified sample is to order a population in some way and then select members of the population at regular intervals. - FALSE.

This can be re written as :The method for selecting a systematic sample is to order a population in some way and then select members of the population at regular intervals.

Explanation for stratified sampling:

In stratified sampling, the members of a population are divided into two or more strata with similar characteristics and then a random sample is selected from each strata. This way ensures that members of each group within a population will be sampled.

Explanation for cluster sampling:

The method for selecting a cluster sample is to order a population in some way and then select members of the population at regular intervals.

In cluster sampling, the population is divided into​​ clusters, and all of the members of one or more​ clusters are selected.

what is the slope of the line that passes through the point -4 -3 and 14 0 right your answer in the simplest form
Kazeer [188]

Answer:

1/6

Step-by-step explanation:

m = y2-y1/x2-x1

m = 0-(-3)/14-(-4)

m = 0+3/14+4

m= 3/18

m = 1/6

Therefore, the slope of the line is 1/6.

One end of a ladder 32 feet long is placed 10 feet from the outer wall of a building that stands on the ground level. How far up
ladessa [460]

Answer:

30 ft

Step-by-step explanation:

This is a classic right triangle problem, where the length of the ladder represents the hypotenuse, where the ladder is lengthwise from the building is the base of the triangle, and what we are looking for is the height of the triangle.  Pythagorean's Theorem will help us find this length.

32^2-10^2=y^2 so

1024 - 100 = y^2 and

y = 30.4 so 30 feet

In right triangle ABC, if angle A is 90 degrees, angle C is 34 degrees, and AC is 71.4, find BC.
AURORKA [14]

We are given that

In right triangle ABC, if angle A is 90 degrees, angle C is 34 degrees, and AC is 71.4, find BC.

Solution

We will first draw a diagram to illustrate the information

Above we want to find x

The method to use is SOHCAH

From the right angle triangle above we have above, we have the adjacent side and we want to find the hypotenus, so we use cosine

i.e

\cos 34=\frac{71.4}{x}

We need to solve for x here

\begin{gathered} x=\frac{71.4}{\cos 34} \\ x=86.12396152 \\ x=86.1\text{ (to the nearest tenth)} \end{gathered}

Thus, |BC| = 86.1 (to the nearest tenth
