The scatterplot below was created from a table of values and represents the relationship between the number of seconds spent doing sit-ups and the number of sit-ups completed for some of the members of a physical education class. A graph titled Time versus Sit-ups has Time (seconds) on the x-axis and sit-ups on the y-axis. 8 points are plotted. Plots pointed are (10, 16), (20, 20), (20, 30), (20, 40), (25, 30), (30, 35), (35, 45), (45, 48).

Assuming that none of the data points overlap and that all the data points were plotted, how many data points were in the table?

You are remodeling your kitchen. you’ve contacted two tiling companies who gladly told you how long it took their workers to tile of a similar size jim completed half the floor in 8 hours. pete completed half of the other floor in 7 hours. if pete can lay 20 more tiles per hour than jim, at what rate can jim lay tiles
