You have a bag with 12 balls, 4 yellow and 8 blue. You pull one ball at random and put it back before you pull the next one. Draw a tree diagram and calculate P (1 yellow, 2 blue).

How is the interquartile range calculated?

The graph represents this system of equations: 2x + y = 3 2x - 5y = 15 what is the solution to the system of equations represented by the graph? (0, -3) (1,1) (1.5,0) (2.5, -2)

Ted and meg have each drawn a line on the scatter plot shown below: the graph shows numbers from 0 to 10 on x and y axes at increments of 1. dots are made at the ordered pairs 1, 8 and 2, 7.5 and 3, 6 and 4, 5.5 and 4.5, 4.8 and 5, 4 and 6, 3.5 and 7, 3 and 8, 1.9 and 9, 1.2 and 10, 0. a straight line labeled line p joins the ordered pairs 0, 8.5 and 10.1, 0. a straight line labeled line r joins the ordered pairs 0, 8.5 and 7.8, 0. which line best represents the line of best fit? line p, because it is closest to most data points line p, because it shows a positive association line r, because it is closest to most data points line r, because it shows a negative association
