viktelen [127]

Answer:

No, it is not a representative sample

Step-by-step explanation:

The sampling technique used above is more of a random sampling than a representative sampling. Reason is that;

A representative sample is referred to as a group or set selected from a larger population that satisfactorily represent the population in study in accordance to whatever criteria is under study.

The criteria could be age, sex, class, etc.

Another reason why it can't be considered as a representative sample is that, using representative sampling makes sure that all relevant types of people are included in your sample and that the right mix of people are interviewed.

In the question above, anybody can submit his or choice and number of submissions is not limited.

Please help me!!!!!!!!!!!!!!!
Ainat [17]

r = 7.53 so d = 2r = 2(7.53) = 15.06 cm

Area of square = d^2 / 2 = (15.06)^2 / 2 = 113.41 cm^2

Area of circle = 3.14 (7.53)^2 = 178.04 cm^2

Area of yellow region = Area of circle - Area of square

Area of yellow region = 178.04 cm^2 - 113.41 cm^2

Area of yellow region =64.63 cm^2 = 64.6 cm^2 (nearest tenth)

Answer

64.6 cm^2
