The graph below shows the speed of the future "Hyperloop" with the coordinate (8,6,080) labeled on the line. Which choice best completes and described the coordinate (1,r)? A. (1,760); The coordinate (1, 760) described the unit rate of the graph stating the "Hyperloop" will have a speed of 760 miles per hour.

B. (1,760); The coordinate (1,760) described how long it will take the "Hyperloop" to travel 1 mile.

C. (1, 600); the coordinate (1, 600) describes the unit rate of the graph stating that the "hyperloop" will have a speed of 600 miles per hour

D. (1, 600) the coordinate (1, 600) describes how long it will take the "Hyperloop" to travel 1 mile.

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x

From the beginning of the day the temperature rose 15 degrees so that by 4 pm it was 87 degrees. what was the temperature at the start of the day

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
