1. On the graph below, sketch your equation from question 2 that represents the money Alex could earn at the job at the amusement park. -Equation: y = 1/9x + 100

2. on the graph, sketch the inequality that represents the number of hours alex could work at the amusement park.

-Amt. of hours: x<= 320

3. then on the graph, sketch the inequality the represents the amt. of money Alex needs to earn.

-Amt. of money needed to earn: y<=2200

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
