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.
Hello again,
We know that the clock has rectangular shapes, and the clock face is circle.
Area of the clock is:
15×8=120 square inches
To find the area of the circle:
πr^2. However, we did not know the radius yet, but we had circumference of the circle which is 6 inches
C=2πr
6=2πr
Divided 2 from both side
3=πr
Divide π or 3.14 from both side
r≈1 inches
Area of the clock face is:
1×1×3.14
≈3.14.
To find the area of the clock that does not covered with clock face take:
120-3.14=116.86 square inches. Hope it help!
Since only 1/10 arrived, you multiply this number by 4,000 which gives you 400. The answer is 400.
Answer:
171.9 degrees.
Step-by-step explanation:
The factor is 180/π.
So 3 radians = (3*180)/π
= 171.9 degrees.
