Select the correct answer from each drop-down menu. If AB = DECA = FDangle B is congruent to angle Eangle A is congruent to angle D, then ∆ABC and ∆DEF are congruent by the ASA criterion. If AB = DEangle B is congruent to angle ECA = FDangle A is congruent to angle D, then ∆ABC and ∆DEF are congruent by the SAS criterion. ∆ABC and ∆DEF are congruent if angle A is congruent to angle DAB = DEAB = DF.

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
