Answer:
Julie weighs 35 lbs, Ted weighs 70 lbs, Mike weighs 105 lbs.
Step-by-step explanation:
Let the weight of Julie be
Given:
Ted weighs twice as much as Julie
Weight of Ted =
Mike weighs three times as much as Julie.
Weight of Mike =
Together, Ted, Mike, and Julie weigh 210 lbs.
Solving above we get;
Hence Julie weight is 35 lbs.
Weight of Ted =
Hence Ted weight is 70 lbs.
Weight of Mike =
Hence Mike weight is 105 lbs.

Answer: A) -0.83</h3>
Without the actual numeric data coordinates, it is impossible to compute the true r value. Though we can estimate. The data points are negatively correlated in a fairly strong manner. We can draw a straight line close to all of these points, so the r value is going to be fairly close to -1. The closer r is to -1, the stronger the negative correlation. Having r = -1 exactly means all of the points fall on some single straight line that slopes downward.
Choice B is the next best choice, but its correlation isn't as strong. So that's why I ruled it out. Choices C and D are ruled out immediately since they are positive values.
