1. Mr. McClellan compared the weights (in pounds) of pairs of elk antlers dropped at Mount St Helens NVM and Rocky Mountain NP.
He tabulated them in the following colored data tables. Purple: Weight of elk antler pairs at Mount St Helens NVM: {34, 34, 30, 30, 30, 28, 28, 26} Red: Weight of elk antler pairs at Rocky Mountain NP: {40, 38, 36, 36, 36, 36, 34, 32} (a) Create a line plot for each data set. (b) Calculate the following for each set of data: a. Purple Mean: b. Red Mean: c. Purple Median: d. Red Median: e. Purple MAD: f. Red MAD: (c) Calculate the means-to-MAD ratio for the two areas of collection. (d) What inference can be made about the areas in regard to weight of dropped elk antlers? Explain. Answer:

Answer:
BD = 16
Step-by-step explanation:
By applying mean proportional theorem in the given right triangles,
AD × CD = BD²
8 × 32 = BD²
BD = √256
BD = 16
Therefore, measure of side BD = 16 units.
