What can you do when the unit prices for two comparable items are listed using different units of measure? a. the secondary units don’t affect the cost. as long as both prices are in dollars or cents, you can compare the two. b. the unit prices are based on the cost of the whole package, so divide each base cost by each unit price to get comparable units. c. use conversion rates to change one unit into the other unit, so that both prices are listed using like units. d. unit prices are ratios, so you can add the two prices together and divide by the smaller unit price to get a usable number.

Find the dimensions of the circle. area = 64π in.² r= in.

The equation line of cd is y=-2x-2. write an equation of a line parallels to line cd in slope-intercept form that contains point (4,5)

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
