Which of the following represents a valid probability distribution? probability distrbution a p(x) -0.14 0.6 0.25 0.29 probability distrbution b p(x) 0 0.45 0.16 0.39 probability distribution c p(x) 0.45 1.23 -0.87

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.

step-by-step explanation: just trying to get points sorry : (

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.

parallel lines have the same slope. so if the green line has a slope of -4, the slope of the red line is also -4.
