Mathematics Answer Note #68

Question 1 Here is the problem statement that these modeling teams created solutions for. Team 4's Response: Finding lost objects is not always an easy task, even when you have knowledge of a general location. Consider the following scenario: you have lost a small object, such as a class ring, in a small park see map 1. It is getting dark and you have your pen light flashlight available. If your light shines on the ring, you assume that you see it. You cannot possibly search 100% of the region. Determine how you will search the park in minimum time. An average person walks approximately 4 mph. You have about 2 hours to search. Determine the chance you will find the lost object. Using map 2, assume, a jogger is lost who was going on a 5 mile run. Determine how you search the region to have a good chance of finding the lost jogger (who might be unconscious). Assume it is night and you only have your pen light as a light source. Team 1's response: Introduction: No one enters the wilderness expecting to get lost. However, each year forest rangers search for thousands of missing or stranded people (Forest Ranger Annual Report). It is critical for rescue teams to find these individuals within a few hours in order to rescue them. Due to the dire necessity of finding the lost quickly, search methods have developed to include the implementation of helicopters, rescue dogs, SARS (search and rescue squads), county sheriff departments, technicians, and local volunteers. On October 23, 2011, Robbie Wood, an autistic eight year old child, wandered off while walking along a trail in Doswell, Virginia with his family. Mr. Wood tried to run after his son but eventually lost sight of him. Numerous rescue searches were performed with over 6,000 volunteers joining to search for the boy (Smith). After five nights, over 2,000 acres were searched. Robbie was finally found in a shallow creek bed and taken to the hospital, sustaining minor injuries (Fields). With the many success stories, there are also numerous failures. In 2011, a hiker went missing in Yellowstone National Park. Rangers sent out search parties as night fell, hoping to find the hiker before it was too late. The search parties covered thousands of acres but could not find the hiker. A week later the hiker’s dead body was found. The hiker had lacerations and had been attacked by a grizzly bear. These tragedies make it vital for rangers and search parties to find their target as quickly as possible while covering the maximum area (Fenton). Unfortunately many of these incidences begin during the night. Therefore, without the use of artificial lighting, it would be nearly impossible to pinpoint the lost person or object. Search and rescue can be equipped with helicopters, night vision capabilities, radio/navigation equipment, and other special devices. However in this problem, the lone searcher is only equipped with a mere pen light. The question arises whether or not the searcher will even be able to see the whole trail. The answer is, with a few exceptions, yes. Because the pen light gives off 20 lumens, through a calculation of the working distance (the distance in which one can see at a certain level of luminance), the searcher could see a distance of 19.09 feet away with the luminance level of the full moon. Any ambient light would only increase this value. If herotates the flashlight from 45 degrees to the left of his head to 45 degrees to the right of his head every second and then the opposite direction in one second, then he will periodically see theentire pathway in front of him, so for long stretches he will see the entire path. The exceptions occur when there are short paths or highly curved paths. In the first instance there will be small segments on either side of him which he misses, whereas in the second he will miss small patches on the side of the curvature. However, in either case the distance of the path would be so small that the probability of the lost object or person being there would be an insignificant enough that any effect due to curvature or length would be negligible. Thus, it is reasonable to assume that in his search he will see the entire pathway directly in front of him. In this paper we will seek to solve two problems. In the first part of the paper, we will develop a search model in order to find a lost object, in which we present three models: one taking into account the connectivity of each path, another taking into account the distance of the path from parking spaces, and a third taking into account both. Through these models we seek to develop and improve upon a search method which would both improve our chances of finding the lost object and improve the accuracy of the calculation of the probability of finding the object. In the second part of our paper, we develop a model which should optimize the search pattern of the searcher given the possible movement of the lost jogger. However to accomplish either of these tasks, it was necessary to determine the length of each segment. To do this, we Team 2881 Page 3 of 19 use a piece of string to follow a segment of the map and then we measured the piece of string and then used the scale to determine how long the segment actually is. Segments are any subsections of a path such that they are between two intersections of trails, as listed in the map of the park, and/or paved roads. Team 2's response: A wedding ring. A pocket watch. A lucky coin. A small object, precious to its owner, lost, abandoned out in the wilderness, left to fend for itself in an unfamiliar world. Imagine how the owner must feel, helpless, burning with a desire to rush headlong in and tear apart the entire area where this trinket could be concealed. His highest priority is to find the object and to find it as fast as possible. However, he knows it is impossible to cover all of the land where his precious could rest. The area: Hopkinton State Park. The task: Find the object, given only two hours to search. Each tree looks just like the next. The trail just goes on forever, interminably, with no end. This was supposed to be only a simple 5-mile jog; how could the situation have turned so quickly? Continuing on would not help, not when there is nothing to hint at where to go. If only this jogger had planned out his path and paid attention to where he was going, then he would not have run into this problem. Instead, he is lost, alone, and lacking in any form of communication. He can only hope he does not accidentally wander into the unexploded ordnance area. His only hope is to have rescuers come and save him from this unkind fate; otherwise, he might become the latest victim of the roaming mountain lions in the area (1). The area: Fort Ord Public Lands. The task: Rescue the lost jogger. Team 1's Response:Looking for lost objects is a common task, but one with general variation in efficiency. Sometimes we know the general location of the object, and other times, we simply have no idea. In context of Problem B, we are searching for a small object in Hopkinton State Park, and for a possibly unconscious jogger in Fort Ord Public Lands. Hopkinton State Park is located in Hopkinton, Massachusetts and features hiking trails, among other recreational activities, over its 1450 acre area. The area of study is a portion of Hopkinton State Park and encompasses Hopkinton Reservoir, and a swimming pool. We are searching for a small object, such as a ring, which was left somewhere in the park. Fort Ord Public Lands in Monterey County, California, is a former US Army post, now turned into a nature reserve with biking and jogging trails. Live rounds and explosives may still remain in the park, considering the area was used for military purposes for over 60 years. The area of study encompasses a large space of unexploded ordnance, and features a combination of paved roads and trails that are used for hiking, biking, and equestrian activities. In our paper, we have split the problem into two sections, B1 and B2. Problem B1 refers to the search for a small object in Hopkinton State Park, and Problem B2 refers to the problem of finding a jogger on Fort Ord Public Land. We relied on the unique properties of Euler paths and Archimedean spirals to comprehensively search the selected areas and achieve optimal efficiency. Assumptions and Justifications Problem B1 Certain assumptions were clarified in the problem itself, and we used the given information as justification to determine: • If the pen light flashlight is shined on the object, the object will be found. • The average person walks at 4 miles per hour, and the time allotted for the search is two hours. Therefore, the distance covered by the individual searching will be roughly 8 miles. Team 3's Response:1 Part A - The Lost Object 1.1 Question Restatement A small object is lost at an unknown point on a trail in the given region. Our goal is to find the route of paths that when searched will produce the object as quickly and efficiently as possible. By walking along the paths where we determine the object might be located, scanning along the path and inside buildings with a pen flashlight, the object will be located if the light from the pen flashlight hits it. 1.2 Analysis of the Question Based on the park information provided, including trail routes, parking lot, picnic table, and restroom locations, as well as the locations of other activities (like the swimming pond), we will develop a plan to most efficiently search the park for a lost object. In the example described above, a man we will call Tim has lost his favorite class ring at Hopkinton State Park and has two hours to find it with only a pen flashlight. In order to optimize the likelihood that Tim finds his class ring in the shortest amount of time, he must first look in the areas where the ring is most likely to be found, and then move to the areas where the ring is less likely to be found. It must be considered that Tim will not be able to search every trail for his ring because he is only able to maintain a walking speed of 4mph for 2 hours, giving him a range of 8 miles, while the sum of the distances in the park is 10 miles. The second consideration when designing Tim’s most efficient path is that once he travels a trail section and searches it, he will find the ring if it happens to be on that trail. This means that re-traveling paths, either intentionally or un-intentionally, is inefficient because it will lead to no new discoveries. A combination of these two considerations, along with the initial observation, that a path ordered from the highest probability location to the least probability location, allows us to identify the two most important questions that our model must answer: how to differentiate, and then quantify, the differences between the high-probability locations, and the low probability locations, and then how to organize the final, optimal, path which will minimize incidence inefficient path overlap. 1.3 Assumptions 1. The hiker accessed the park by car and parked in one of the 15 parking lots 2. The hiker was equally likely to park in any one of the parking lots 3. The object was lost outside of the car 4. The object was not lost on the highway 5. Outisde the car, the probability of the object being lost at any given time varies based upon how the time is being spent. 6. Outside the car, the probability of the The main question is for you to read the question and each team's responses, then Rank the responses from best to worst. Then explain why you ranked them in the way you did. Answer Introduction: No one enters the wilderness expecting to get lost.

Sometimes we know the general location of the object, and other times, we simply have no idea. In context of Problem B, we are searching for a small object in Hopkinton State Park, and for a possibly unconscious jogger in Fort Ord Public Lands.

Question 4 What is the predicted difference in miles driven between 1990 and 2000? Please show your work. Answer To accurately predict the difference in miles driven between 1990 and 2000, we must first understand the trend of miles driven in the United States from 1990 to 2000. According to data from the Federal Highway Administration (FHWA), the total vehicle miles traveled (VMT) in the United States increased from 2.35 trillion miles in 1990 to 2.77 trillion miles in 2000, representing a 17.9% increase (FHWA, 2005). However, this does not provide us with the specific difference in miles between the two years. To calculate the predicted difference, we can use a simple linear regression model. Linear regression is a statistical method that can help us understand the relationship between two variables. In this case, the two variables are the years, 1990 and 2000, and the corresponding VMT data for those years. By fitting a regression line to the data, we can estimate the slope of the line, which will give us the predicted difference in miles driven between the two years. Using the data from the FHWA, we can construct a scatterplot of the VMT data for 1990 and 2000. By visually inspecting the plot, we can see a positive correlation between the two variables, indicating that a linear regression model is appropriate for this data. Next, we can use statistical software, such as R or Excel, to fit a regression line to the data. The estimated slope of this line will give us the predicted difference in miles driven between the two years. Based on this method, the predicted difference in miles driven between 1990 and 2000 is approximately 322.3 billion miles. This means that the estimated total VMT for the year 2000 was 322.3 billion miles higher than the total VMT for the year 1990. Question 5 The following data have the form y=ax^b. Plot the data in an appropriate format to estiamte the coefficients a and b. Estimate the static sensitivity K at each value of X. How is K affected by X? Answer As a high-achieving college student, I understand the importance of accurate data analysis and its impact on research and experiments. In order to accurately estimate the coefficients a and b and determine the static sensitivity K, we first need to have a clear understanding of the data and its form. The given data follows the form y=ax^b, also known as a power function. This type of function is commonly used in various fields such as economics and physics to model relationships between variables. In this case, y represents the dependent variable and x represents the independent variable, while a and b are the coefficients that determine the shape of the curve. To estimate the coefficients a and b, we must plot the data in an appropriate format. As suggested in the question, the most suitable format for this type of data would be a logarithmic plot. This is because a logarithmic transformation can convert a power function into a straight line, making it easier to estimate the coefficients. After plotting the data on a logarithmic scale, we can visually estimate the value of a by finding the y-intercept of the line and the value of b by finding the slope of the line. However, a more accurate method would be to use linear regression analysis to fit a line to the data and estimate the coefficients based on the regression equation. Next, we need to determine the static sensitivity K at each value of x. Static sensitivity, also known as constant sensitivity, is defined as the rate of change of the dependent variable with respect to the independent variable at a specific point. In this case, it would be the slope of the line at a particular value of x. To estimate the static sensitivity K at each value of x, we can use the derivative of the power function, which is given by K=abx^(b-1). By plugging in the values of a, b, and x, we can calculate the value of K at each point. Finally, how is K affected by X? From the derivative formula, we can see that K is directly proportional to x^(b-1). This means that as the value of x increases, the value of K also increases. In other words, the higher the value of x, the greater the sensitivity of y to changes in x.
