Answer:
I'd use a Non-probability Sampling Method.
Explanation:
The question is already laced with criteria - Heights of Buildings in New York.
This means that there are certain buildings that won't fit in the sample. In a non-probability sample, objects or subjects are elected based on specified criteria that are not random. This means that not all objects/subject have a c<em>hance</em> of being included in the sample.
It is assumed that the question/assignment centers around high rise buildings.
Therefore, one storey buildings and bungalows that are within and outside New York will not be included in the sample.
Under the Non-Probability Sampling Method, it is essential to note that there are other subgroupings of sampling techniques. They are:
- Convenience Sample
- Voluntary Sample
- Purposive Sample
- Snowball Sample

Answer:
This sequence is arithmetic, and the next term is 25
Step-by-step explanation:
The common difference of the sequence is 6, so the next term is 19+6=25.
The difference between the consecutive terms is constant => sequence is arithmetic.
<u>7-1=6</u>
<u>13-7=6</u>
<u>19-13=6</u>
Answer:
The no. of variations in sign is 3
Step-by-step explanation:
Variation in sign occurs when every single time a negative product is produced by a pair of consecutive terms.
Therefore, the determination of the number of changes in sign in the given sequence is must.
Therefore, we take the product of the pair of consecutive terms as:
= - 3, variation in sign
= - 6, variation in sign
= 10, no sign variation
= - 20, variation in sign
= 24, no sign variation
You can see the polygon in the attached figure.
It's a trapezoid, so it's not equilateral, nor regular.
Here, Just substitute their values,
4x + 3y
= 4(3) + 3(6)
= 12 + 18
= 30
In short, Your Answer would be 30
Hope this helps!
