HURRY FAST GIVING Ms. Davis teaches jewelry making at the community college. Each of her 25 students will need 1Eleven-twelfths feet of leather cord to make necklaces. The cord is sold in 5-foot spools, and she cannot purchase a partial spool. Which equation would provide the best estimate of how many spools of cord she needs to buy? StartFraction 25 plus 2 over 5 EndFraction = 5.4 StartFraction 25 times 2 over 5 EndFraction = 10 = 15 = 62.5

Lines a and b are parallel. what is the value of x? -5 -10 -35 -55

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
