Three students are working to find the solution set of this system of equations: y = 3x + 10 2y = 6x – 4 Use the drop-down menus to complete the statements about each of their methods

Mia:
Mia correctly graphs the two lines and sees that they ( Intersect, do not intersect, are on the same line) This means the system has (one, zero, Infinitely many) solution(s)

Roberto:
Roberto correctly sees that the y ( can, cannot) be equal to both 10 more than three times a number and 2 less than three times a number at the same time.

Delmar:
Delmar correctly concludes that because 3x + 10 and 3x - 2 will ( Sometimes, never, always) be equal, the system has (one, zero, Infinitly many) solution(s)

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
