The independent variable of a data set is y, while the dependent variable is z. Which of these is a response variable?
ОА. у
O B. Neither y nor z
O C. z
D. Both y and z

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.

its less than 713.21 but greater than 5.2
