Answer:

Observational study/The sample is too small

Explanation:

The study is observational since there is no attempt to modify nor apply any kind of treatment.

An important problem in this study is the quantity of the sample. It is explained that the research selected only 8 individuals, which is not a significant sample. The minimum number of samples should be at least 30.

kolezko [41]

Ethnic Enclaves is the correct asnwer.

Throughout history, we see immigrants moving from one place to the other and  often staying in neighborhoods with people with whom they shared the same nationality, culture and similar habits. In Sociology and Anthropology, an ethnic enclave is defined as a geographic area where a community that shares similar background maintains a strong sense of identity and customs from their place of origin. These ethnic enclaves were the most common option for these immigrants since they felt  more welcome and safer from prejudice and discrimination.

The management of a large store wishes to add a fenced-in storage yard of 20,000 square feet, using the building as one side of
Marat540 [252]

Answer:

minimum fencing = 400

Explanation:

area = xy

20000 =xy

y =\frac{20000}{x}

total fencing = x+y+y

= x+2(\frac{20000}{x}

= x +\frac{40000}{x}

now for minimum fencing

\frac{d}{dx}c = \frac{d}{dx}(x +\frac{40000}{x}) = 0

after solving we get

x = 200

therefore

y = 100

minimum fencing  = x +2y

                               = 200+2*100 = 400
