Answer:

Square: x= +or - \sqrt{7}, Triangle: x= + or - \sqrt{23}

Step-by-step explanation:

For the square

4x^{2}=28

dvide by four:

x^{2}=7

Take the square root of both sides

x= +or - \sqrt{7}

For the Triangle

(1/2) (2x) (2x)=46

2x^{2}=46

Divide by 2

x^{2}=23

x= + or - \sqrt{23}

Suppose you want to learn more about the heights of the buildings in New York City. How would you choose a sample of the buildin
natulia [17]

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:

  1. Convenience Sample
  2. Voluntary Sample
  3. Purposive Sample
  4. Snowball Sample

Cheers!
