Sue logs on to her e-mail once during the time interval from 7:00am to 8:00am.
Assuming that all times are equally likely, find the probability that she will log on during
the interval from 7:30am to 7:45am.

true? is that what you're asking or do you mean something else?

there are infinitely many solutions.

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.
