In the figure on the right, Identify which curve corresponds to the population of foxes and which one to the population of hares. Provide a brief justification. An interaction between populations of foxes and hares can be modeled using a pair of coupleddifferential equations for F'(t) and H'(t), where F(t) and H(t) denote the populations of foxes andhares, respectively, at time t. Consider the plots below depicting particular aspects of this system.(You can see a color version of these plots in the file on moodle.)HA(5, 10)10148.121084.6.42.6.10 F0.00.51.01.52.02.53.0Population

Twenty five right-handed students were asked to turn a knob (using their right hands) that moved an indicator by screw action. There were two identical instruments, one with a right-hand thread (the knob turns clockwise) and the other with a left-hand thread (the knob turns counterclockwise). The data presented below gives the times (in seconds) each subject took to move the indicator a fixed distance: Obs.# R Obs.# R L L Obs.# R 1 113 8 116 166 22 100 2 105 105 9 75 146 23 89 3 130 133 10 96 123 24 85 4 101 108 11 122 135 25 88 5 138 115 12 103 6 118 170 13 116 7 87 103 14 107 At 1% level of significance, can we conclude that these right-handed students found it easier to use the knobs with a right-hand thread?

Review the data in the Table 1, entitled, "Average Annual Salaries for Bachelor of Science Graduates, Summer 2016-Spring 2017". Using this data, create a chart (with a title, labeled axes, and a legend) comparing the average salaries that you could use to guide high school students who want salary influence the type of engineering major that they will choose. Consider, which fields tend to make the most money? Write a recommendation letter addressed to a high school student who wants to select an engineering field based on the salary; using a comparison of the data, recommend which majors they should most closely consider.

The graph to the right shows the braking distances for different cars measured under the same conditions. Describe the ways in which this graph might be deceptive. How much greater is the braking distance of Car A than the braking distance of Car C? Draw the graph in a way that depicts the data more fairly. In what way might the graph be deceptive? A. There are errors in the graph. B. The units in the graph are not consistent throughout. C. By starting the horizontal axis at 100, the graph cuts off portions of the bars. D. The graph compares more than two values. How much greater is the braking distance of Car A than the braking distance of Car C? A. The braking distance of Car A is about 120 ft greater than the braking distance of Car C. B. The braking distance of Car A is about 30% greater than the braking distance of Car C. C. The braking distance of Car A is more than twice the braking distance of Car C. D. The…

Suppose a researcher collects data on the air pollution levels, measured in milligrams per cubic meter, for both urban and rural areas in 35 states. The data is plotted with urban air pollution levels on the horizontal axis and rural air pollution levels on the vertical axis. Nevada is an outlier in the ?x‑direction. What must be true about this state? The urban air pollution levels for this state are much higher or lower than the rest of the states in the data set. The rural air pollution levels for this state are much higher or much lower than the rest of the states in the data set. This state is an influential observation. The rural air pollution levels for this state are much higher or lower than other states in the data set that have similar urban air pollution levels. The absolute value of the residual of this state is large.
