The dot plots below show the scores for a group of students for two rounds of a quiz Which inference can be made using the dot plots There is no overlap between the data
Round 1 scores were higher than round 2 scores
Round 2 scores were lower than round 1 scores
The range of round 1 is smaller than the round 2 range

answer: idk

step-by-step explanation:

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.
