an experiment will be conducted in which 20 pepper plants are randomly assigned to two groups. the plants in group 1 will receive the current fertilizer, fertilizer a, and the plants in group 2 will receive a new fertilizer, fertilizer b. all other growing conditions, including amount of sunlight and water, will be kept the same for the two groups. the growth of the pepper plants will be compared for the two groups. what are the experimental units in this experiment?

#12 the answer is the third option

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
