- If you travel 100 miles in two hours, then your average speed for the trip is Average speed=_________=________arrow_forwardEnter the data from Table 2 into a graphing calculator and graph the ranking scatter plot. Determine whetherthe data from the table would likely represent a function that is linear, exponential, or logarithmic.arrow_forward7. The populations of some predatory animals vary periodically. Assume that the population of foxes in a forest varies with time. When records started being kept, there were only 180 foxes, the minimum, and 6 years passed before they reached the minimum again. The maximum number of foxes was 1000. Complete each of the following 2 activities (A - B) for Question 7. 7A. Write the reflected cosine equation that would fit this situation.arrow_forward

If the average daily traffic is 450, what is the accident rate per hundred million vehicle miles if the roadway is 100 miles in length? A. 713.10 B. 846.40 C. 710.30 D. 844.60arrow_forward*. Baseball pitchers try to prevent hitters from reaching base. One way to measure the eflectiveness of a pitcher is WHIP, which is calculated by the formula: walks + hits WHIP innings pitched The table shows the age and WHIP for all 17 vears of Bob Gibson's MLB hall-of-fame career. Age WHIP Age WHIP Age WHIP 23 1.533 29 1.157 35 1.185 24 1.673 30 1.027 36 1.129 25 1.443 31 1.089 37 1.108 26 1.151 32 0.853 38 1.417 27 1.257 33 1.102 39 1.670 28 1.169 34 1.190 (a) Use the calculator to find a quadratic model for these data using age as the explanatory variable. (b) Sketch the scatterplot, along with the quadratic model. (c) Calculate and interpret the residual for observation when Bob was 24 years old."arrow_forward3.)
