Explain the difference between a simple random sample and a systematic sample.

Mathematics
1 answer:
Stells [14]3 years ago
5 0

Answer:

C

Step-by-step explanation:

Simple random sampling otherwise called probability sampling involves selecting a subset of a part of a population in which each member of the population has equal chances of being selected while systematic sampling involves the use of sampling interval which is determined by dividing the population by the sample size and a random starting point is selected. for example let say we have a population of 1000 people and we want to systematically select 50 people, 1000 /  50 = 20, it means after choosing a random starting point, we select every 20th person after the starting point until the desire sample size has been attained.

Answer: y \in R; y \neq 0
Explanation: For this, it is often best to find the horizontal asymptote, and then take limits as x approaches the vertical asymptote and the end behaviours.

Well, we know there will be a horizontal asymptote at y = 0, because as x approaches infinite and negative infinite, the graph will shrink down closer and closer to 0, but never touch it. We call this a horizontal asymptote.
So we know that there is a restriction on the y-axis.

Now, since we know the end behaviours, let's find the asymptotic behaviours.

As x  approaches the asymptote of 7⁻, then y would be diverging out to negative infinite.
As x approaches the asymptote at 7⁺, then y would be diverging out to negative infinite.

So, our range would be: y \in R; y \neq 0

Find the length of ST
Andru [333]

Answer:

ST = 12

Step-by-step explanation:

By AA Similarity, triangles ASR and EST are similar.

The ratio of the lengths of the sides of triangle ASR to those of EST is 6/8 or 3/4.

\dfrac{SR}{ST} = \dfrac{3}{4}

Also,

SR + ST = 21

By a rule of proportions, you get

\dfrac{SR + ST}{ST} = \dfrac{3 + 4}{4}

\dfrac{21}{ST} = \dfrac{7}{4}

7ST = 4 \times 21

7ST = 84

ST = 12

4x+32=24<br> show your work
sp2606 [1]

Answer:

x = -2

Step-by-step explanation:

Original equation:

4x + 32 = 24

Subtract 32 from 24

-8

The equation should look like this now:

4x = -8

Divide both sides by 4

x = -2

Hope this helps :)
