Why is it important to use a straightedge when copying a line segment?(1 point) Since line segments can be any length, it is important to use a straightedge for longer line segments. A straightedge is less important when drawing short line segments though. Since lines must be straight, and line segments are sections of lines, a straightedge must be used to keep the line segment straight. Since rulers are straightedges, it is important to use them to make sure the length of line segments are the same. Using a straightedge helps you to draw the new line segment at the same angle as the original line segment.

Mercury poisoning is dangerous overload of mercury within the body. a major source of mercury within the body, a major source of mercury poisoning is consuming fish that contain mercury. certain fish are more prone to having higher levels of mercury than others. the pie chart shows the distribution of four breeds of fish at a hatchery. the hatchery has approximately 6,000 fish. a biologist from the centers for disease control and prevention randomly test 5% of each breed of fish for mercury content. her findings are shown in the following table. based on the biologist's findings, if a single salmon is randomly selected from those that were tested, what is the probability that this particular fish would have a dangerous mercury level? a) 0.001 b) 0.004 c) 0.02 d) 0.08
