What is a scatterplot and how does it us? choose the correct answer below. a. a scatterplot is a formula that fits a straight line to data points, which plot the data. b. a scatterplot is a graph of paired (x, y) quantitative data. it provides a visual image of the data plotted as points, which show any patterns in the data. c. a scatterplot is a table of paired (x, y) quantitative data sorted from least to greatest, which show the range of the data. d. a scatterplot is a graph of paired (x, y) qualitative data. it provides an organized display of the data, which show patterns in the data.

If a(0,0,0) and b(2,2,2) are points in coordinate space, how many paths are there from a to b that move from one lattice point to another in the positive x-,y- or z- direction?

Match the following terms with their definitions. 1. bisector of a segment ray ba and ray bc are opposite rays if a, b, and c are collinear and b (the endpoint of both rays) is between a and c. 2. opposite rays a ray, , is the set of points beginning at point a and going infinitely in the direction of point b. 3. collinear points a line or segment that intersects the segment at its midpoint. 4. betweenness of points a set of two or more points all on the same line. 5. ray the distance between the endpoints of a segment. 6. space point b is between a and c if a, b, and c are collinear and the equation ab + bc = ac is true, where ab, bc, and ac are the distances between points a and b, b and c, and a and c, respectively. 7. midpoint of a segment a set of two or more points all on the same plane. 8. coplanar points the point on a segment that divides the segment into two equal segments. 9. length of a segment the set of all possible points. 10. line segment the set of two different endpoints and all points between them.
