Wauchope and McDowell (1984) want to predict the amount of phosphate that can be absorbed in a fixed volume of soil. They suspect that the amount of iron and aluminum as well as the acidity of the soil may play a role. Do a complete linear analysis for all these factors as well as possible interactions on predicting the phosphate. Give the best model and analysis tables to go with your model.

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
