Team up with two to three other students and jointly decide how you would organize, order, and locate the data used in the following application. Be prepared to present your group’s design to the rest of the class. The program to be developed is a menu-driven program that will keep track of parking tickets issued by the village that is hiring you. When a ticket is issued the program must be able to accept and store the following information: ticket number, officer number, vehicle license plate state and number, location, violation code (this indicates which parking law was violated), and date and time written. The program must store information on the amount of the fine associated with each violation code. When a ticket is paid the program must be able to accept and store the information that it has been paid, the amount of the payment, and the date the payment was received. The program must be able to accept inquiries such as displaying the entire ticket record when a ticket number is entered. The program must also be able to produce the following reports: • A list of all tickets issued on a specific date, ordered by ticket number • A list of all tickets for which payment was received on a specific date and the total amount of money collected that day • A report of all tickets issued in a one-month period, ordered by officer number, with a count of how many tickets each officer wrote • A report of all tickets that have not yet been paid, or for which payment received was less than payment due, ordered by vehicle license number

$\bullet$ $\bullet$ Automobile accident analysis. In an auto accident, a car
hit a pedestrian and the driver then slammed on the brakes to
stop the car. During the subsequent trial, the driver's lawyer
claimed that the driver was obeying the posted 35 mph speed
limit, but that the limit was too high to enable him to see and
react to the pedestrian in time. You have been called as the
state's expert witness. In your investigation of the accident site,
you make the following measurements: The skid marks made
while the brakes were applied were 280 ft long, and the tread on
the tires produced a coefficient of kinetic friction of 0.30 with
the road. (a) In your testimony in court, will you say that the
driver was obeying the posted speed limit? You must be able to
back up your answer with clear numerical reasoning during
cross-examination. (b) If the driver's speeding ticket is $\$ 10$ for
each mile per hour he was driving above the posted speed limit,
would he have to pay a ticket, and if so, how much would it be?

Okay. So we're looking at problem 58. We're looking to see what data support the hypothesis that changes in leaf color are genetically controlled. So let's take a look at what we did. So it looks like we placed 20 tobacco seeds of the same species on a moist paper towel in two different Petri dishes dish a. And dish beat. And we wrapped dish A. In an opaque cover so the light couldn't get through as easily but did not wrap dish beat after seven days we observed are Petri dishes with our seeds in them and remove the covering from dish A. And left them under normal light conditions for the rest of the experiment. So let's look at the data that we were able to collect. So option A. The number of yellow leaves seedlings and dish a. On day seven. Well day seven was the day removed. The opaque covering to the number of yellow leaved seedlings was probably an environmental control. Mm. Okay, let's look at the data from B. Yeah, Be says the number of germinated seeds in dish a. On day seven and 14. So that's examining germination option C. The death of all the yellow leaved seed links. Okay, so that's examining life and death. Mhm. Mhm. And option D. Yeah, the existence of yellow leaved seedlings as well as green leaved ones on day 14 and dish B. So dish B. Was the one under normal light conditions throughout the duration of the experiment. And it's looking at both yellow colored seedlings, yellow color leaves and green colored leaves. So there's the existence of two different colors in the same environment with the same conditions. So the existence of these two colors is probably due to an alil from the parents. Well, the parent plant. Okay, so let's take a look at which one of these is going to support our hypothesis. So A. Is looking at environmental control, but we want something that's genetically controlled. So that's going to be a no option. B. Is looking at germination. Well, we're looking for changes in leaf color, so not going to be C. Is looking at life and death of yellow leaves seedlings that could be a genetic control but there's no changes in leaf color. It's just all the yellow leaf seedlings died. So that's going to be a No. And then our process of elimination, we can definitely say that is deep, but I'm gonna explain why really quickly. So in a leo from the parents, causing a change in leave color is the definition of genetic control. One quick check and problems like these to see whether something is genetically controlled or environmentally controlled is if two different characteristics appear in the same environment. I hope that was helpful

Already. So we're in one of late. We have another hypothetical experiment here and here. We have a student who, uh, take some tobacco sees and puts them in a petri dish. Right. A petri dish, a in a petri dish. Be okay. And there's 20 seats in each, even amount. And then the student wraps. Uh, picture this a in some sort of cover that would exclude light. Right. Then he places them. Ah, three equal distance from a light source. Okay, It's another equal distance from a light source. And he says the cycle to there's 14 hours of light and then followed by 10 hours of darkness. Okay? And for one week, this experiment goes on for one week. Lengthy end takes some some measurements. Right? So we removed the cover from a and say what's going on under the hood here. Curious and heinz Ah, A few interesting things, right? So the first thing to note is that they had less germinating seeds, right? So there is just 12 germinating scenes and this be all 20 Germany. All right? And then, uh, for dish be 15 of them where green and we had five that were yellow, whereas in dish, eh? All 12 were actually this yellow leaved ceiling. But more interesting is the length of the stem was quite different. So and, b, they were shorter. The average length of this time was three millimeters. But the average length of this stem for dish A was actually a little bit taller. They were closer to eight millimeters. Okay? And so then the question of this problem is why? Why would that be longer? Okay. And so just broadly speaking, we could say, Well, there was an elongation of this time, right, because it's it's longer and a that and be in its longer due to a lack of light because that was the conditions of a. But why that might be is fury in sort of plants where they are under shades that there's a plants were covering them right? The response might be to to try to grow and find light. They're going to try to seek it out. They're not getting it now, but maybe if they move a little bit in one direction or another, get taller, they'll find it. And so being in the dark stimulated this elongation response right? So than the correct answer is going to be choice B

Please read the given answer, and after understanding this, you can determine that option B See and option D are incorrect. Only auction ay is the correct answer course can be proved. That is. Issues uses deception When food is plentiful but present in concentrated form, it allows access off food only small groups off. Good. It would be wrong to stay that deceptive behavior is carried out by the board, irrespective offers. Need auction E. That's correct.

Party. We're told that student earns $10 per hour for tutoring in $7 per hour. As a teacher's aide, we're also told that X is number of hours spent tutoring and why is the number of hours per week as ah, teacher's aide, which are just abbreviated as a t. A. We were asked to write the objective function that models total weekly earnings. So it's called Z the total earnings per week. Then we have that SI is equal to well, student earns $10 per hour for tutoring, so there's $10 per hour times X hours per week is 10 x dollars per week tutoring plus and then a student earns $7 per hour as a ta. So seven why dollars per week as a t A. And so there in 10 X plus seven y dollars per week in total in Part B were given the constraints for the student and were asked to write a system of three inequalities modeling these constraints. So we're told that to have enough time for studies student can work no more than 20 hours per week, so we have the total number of hours per week which is X plus Y, must be less than or equal to 20. Tutoring center requires that each tour spend at least three hours per week tutoring. So we have that the number of hours in the tutoring center, which is Knicks, be at least three per week, and tutoring center also requires each tutor spend no more than eight hours per week tutoring. So we're also told that X is less than or equal to eight hours per week. Part C. You're asked to graft the system of inequalities in Part B. We're also told toe only use the first quadrant and its boundary. So before we graph it, let's just rationalize why we're only using the first quadrant. Well, this is because in addition to the three inequality is we found in Part B. We also have that since these air times, it must be greater than or equal to zero so X is greater than or equal to zero, and why has to be greater than or equal to zero? So, in part C, we're dealing only in the first Quadrant. And to graph the first inequality values red first, let's graph the equation X plus y equals 20. This has an X intercept of 20 0 in a Y intercept of 0 20 and since the line is a solution, I'll click these points with a solid line. I'll use the origin is a test point we have that zero is less than or equal to 20 so everything to the left of the red line is a solution. Autographed the second equation in green. Second inequality in green. So first graf X equals three. This is a vertical line at X equals three, and because the wine is a solution, I'll draw a solid line here, and everything to the right of this line is a solution, since the origin is not a solution and I'll draw the third inequality and blue do this autograph X equals eight. This is a vertical line at X equals eight, and since it's a solution, I'll draw a solid line, and we have that. Since the origin is a solution, everything to the left of this blue line is a solution, and so al draw the solution to the system of inequalities in black. The solution is the Quadrangle in Black, which has Vergis ease. 30 80 and then to find with these other two burgesses arm. Let's find the solutions to these systems of equations. So we have. They're section of the red and green lines, this is X plus y equals 20 and X equals three by simply substituting. We have that why is equal to 20 minus three, which is 17. And so we also have the Vertex 3 17 and it's last for Texas, the intersection of the red and blue lines. So this is X plus y equals 20 and X equals eight. Solve this system. Simply subtract he bottom equation from the top and we get why is equal to 12. So we have that eat 12 is the other vertex and parte de you're asked to evaluate the objective function at each of the vergis ease. So we have that or text. 30 Z is equal to 30. At Vertex 80 z is equal to 80. At Vertex 8 12 z is equal to well, this is going to be 80 plus 84 which is 1 64 And at Protects 3 17 z is equal to 30 plus and then 17 times seven. Just 70 plus 49 which is 119. So in 19 plus 30 which is 1 49 in Part E, we were asked to complete the missing portions of a statement. So, statement says the student can earn the maximum amount per week by tutoring for blank hours per week and working as a teacher's aide for blank hours per week. Maximum amount of student can earn each week is blank. So for the first blank, how many hours per week should it student tour to earn the maximum out? Well, recall that we have by a serum that if the objective function has a maximum over the region, determined by the system of linear inequalities, then the maximum will occur at at least one of the vergis ease of this region. And so, looking at her data from Part D, we have the maximum value of Z is 1 64 which occurs. That's the point 8 12 So we have that persons should spend okay hours per week tutoring and how many hours working as a teacher's aide 12 hours per week as a t A and the maximum amount of student can earn each week we determined WAAS 164 dollars per week
