To compare the effectiveness of two detergents at removing common stains (such as mustard, grass, and blood), researchers prepared stained clothing samples. Each sample was cut in half and each of the two pieces was assigned, using a random mechanism, to one of the two detergents. After washing, the two halves were compared with each other. Which term best describes the experimental design used in this study

1/800 is the right answer

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
