Sixteen milk-yielding Ayrshire cows were fed a diet of silage that was supplemented with a vitamin con- tentrate. The following values refer to the milk fat concentration (g/kg) for each cow 20, 38, 44, 49, 42, 21, 48, 47 21, 22, 23, 26, 26, 44, 48, 29 (a) Create a stem-and-leaf display with two lines per stem. (b) What interesting feature of the data is made apparent when put into the stem-and-leaf display? (c) Calculate the mean averagel and median and explain why reporting a center for this data (mean or median) without providing a graph of the data is not very useful. 4. The back-to-back split stemplot shows the lifetimes of 15 Brand X and Brand Y batteries (number down the middle gives the stem and numbers under Brand X and Brand Y are leaves). Brand 21103 997753 3221 4 223334 456889 Key: 2141 or 2 represents 420429 bours for Brand X and Brand Y, respectively (a) What is the longest that any battery lasted? (b) Give a reason someone might prefer a Brand X battery (c) Give a reason someone might prefer a Brand Y battery

The school track has eight lanes. each lane is 1.25 meters wide. the arc at each end of the track is 180. the distance of the home straight and the radii for the arcs in the 1st 4 lanes are given. s=85m r1=36.5m r2=37.75m r3=39m r4=40.25m part one: find the radii of lanes 5 through 8 of the track. show your work. part two: if max ran around lane one, how far did he run? show your work and explain your solution. part three: max wants to run a total of three laps around the track, choose two additional lanes (2-8) for him to run and find the distance around those two lanes. show your work and round to the hundredths. part 4: based on your lane choices in part three, what was the total distance max ran in the three laps around the track?
