A farmer wishes to test the effects of a new fertilizer on her potato yield. She has four equal-sized plots of land. One plot has sandy soil, one has rocky soil, one has clay-rich soil, and one has average soil. She divides each of the four plots into three equal-sized portions and randomly labels them A, B, and C. The four A portions of land are treated with her old fertilizer, the four B portions of land are treated with the new fertilizer, and the four C portions of land are treated with no fertilizer. At harvest time, the potato yield is recorded for each section of land. What is the treatment in this experiment?

A. the four types of soil

B. the soybean yield at harvest time

C. the soybean plants on the various plots of land

D. the tree types of fertilizer

D

Step-by-step explanation:

The treatment in the case given is the testing of the fertilizers. For portions labelled A : Old fertilizers, B : New fertilizers , C : No fertilizers.

Each and every soil is treated with 3 different fertilizers at each and every type of soil, the results are interpreted from harvest of soybeans

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
