Aila's gym class just completed a physical fitness unit. one of the activities was improving flexibility. students had to sit on the ground with their feet in front of them and reach their arms out as far as they could. a scale like the one in the picture below was used to measure their flexibility. aila's measurement at the end of the unit was four more than her measurement at the beginning. if her measurement at the beginning was -2, how far was aila able to reach at the end of the unit?

Which table shows a proportional relationship between miles traveled and gas used?

Which of the following represents the factorization of the trinomial below? x^2+7x-30

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
