A poster is a rectangle long and wide. We want to cover the poster with small stamps. The coverage of each bag of stamps is measured in square inches. (a) Find the area of the poster in square inches.

Use the table of conversion facts, as needed.

(b) We want to cover the poster with small stamps. We don't have any, to begin with, and we can't buy partial bags of stamps. Each bag of stamps covers 98.5 in squares. How many whole bags of stamps will we need to buy in order to completely cover the poster?

(c) If each bag of stamps costs $2, how much will we need to spend on stamps?

If f(x) = 4x – 3 and g(x) = 8x + 2, find each function value a.f[g(3)] b.g[f(5)] c.g{f[g(-4)]}

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
