A 2-column table has 8 rows. The first column is labeled Statements with entries angle A B C is right angle, Line segment D B bisects angle A B C, B, m angle A B D = m angle C B D, m angle A B D + m angle C B D = 90 degrees, m angle C B D + m angle C B D = 90 degrees, D, m angle C B D = 45 degrees. The second column is labeled Reasons with entries A, given, definition of right triangle, definition of bisection, C, substitution property, addition, and division property. Identify the missing parts in the proof. Given: ∠ABC is a right angle. DB bisects ∠ABC. Prove: m∠CBD = 45° A: B: C: D:

Farmers know that driving heavy equipment on wet soil compresses the soil and injures future crops. here are data on the "penetrability" of the same type of soil at two levels of compression. penetrability is a measure of how much resistance plant roots will meet when they try to grow through the soil. compressed soil 2.85 2.66 3 2.82 2.76 2.81 2.78 3.08 2.94 2.86 3.08 2.82 2.78 2.98 3.00 2.78 2.96 2.90 3.18 3.16 intermediate soil 3.17 3.37 3.1 3.40 3.38 3.14 3.18 3.26 2.96 3.02 3.54 3.36 3.18 3.12 3.86 2.92 3.46 3.44 3.62 4.26 use the data, omitting the high outlier, to give a 95% confidence interval for the decrease in penetrability of compressed soil relative to intermediate soil. compute degrees of freedom using the conservative method. interval: to
