Answer:
Convenience sampling.
Step-by-step explanation:
To gather information on customer satisfaction, a researcher goes into each store and interviews six randomly selected customers at each store. This sampling technique is called convenience sampling.
Convenience sampling can be defined as a sampling method which involves the researcher selecting or collecting data that is easily available or choosing the individuals who are easiest to reach in a population. It is a type of non-probability method of sampling where the first or easiest available data source is being used by the researcher without other requirements.
In this scenario, to gather information on customer satisfaction, the researcher went to the store most likely situated in a shopping mall to collect data from six (6) customers in each stores.
<em>Some of the advantages of convenience sampling are low cost, data are collected quickly, lesser rules etc. </em>
Answer:
The side of the square is 5.971 cm
Step-by-step explanation:
If the square fits the circle exactly, then its diagonal is equal to the diameter of the circle. Since the side of the square has a length of
cm, then it's diagonal have the length of
cm. Using the circle's area we can find the diagonal of the square, as shown below:
![area = \pi*r^2\\56 = pi*r^2\\r^2 = \frac{56}{\pi}\\r = \sqrt{\frac{56}{\pi}}\\r = 4.222](https://tex.z-dn.net/?f=area%20%3D%20%5Cpi%2Ar%5E2%5C%5C56%20%3D%20pi%2Ar%5E2%5C%5Cr%5E2%20%3D%20%5Cfrac%7B56%7D%7B%5Cpi%7D%5C%5Cr%20%3D%20%5Csqrt%7B%5Cfrac%7B56%7D%7B%5Cpi%7D%7D%5C%5Cr%20%3D%204.222)
Since the diameter of the circle is the same as the diagonal of the square, then:
![x\sqrt{2} = 2*r \\x = \frac{2*r}{\sqrt{2}}\\x = \frac{2*4.222}{\sqrt{2}}\\x = 5.971](https://tex.z-dn.net/?f=x%5Csqrt%7B2%7D%20%3D%202%2Ar%20%5C%5Cx%20%3D%20%5Cfrac%7B2%2Ar%7D%7B%5Csqrt%7B2%7D%7D%5C%5Cx%20%3D%20%5Cfrac%7B2%2A4.222%7D%7B%5Csqrt%7B2%7D%7D%5C%5Cx%20%3D%205.971)
The side of the square is 5.971 cm
Answer:
169 meters
Step-by-step explanation:
52/4=13 (since it's a square you divide it by 4 because the sides are equal, so each side is 13 meters)
13^2=169 (to find the area you square the length of each side)
Answer:
a is not a linear equation
