here are two highways from City A to City B. Route 1 is on flat terrain, whereas Route 2 is a scenic route that goes through mountainous terrain. During severe winter seasons, one or both routes may be closed to traffic because of heavy snowfalls. Route 2 is obviously more likely to be closed than Route 1 during the winter months. The condition of Route 1 during a severe storm may depend on whether or not Route 2 is open to traffic. Suppose, during a severe storm, the probabilities that the routes will be open are p(R1)=0.75, p(R2)=0.50, p(R1R2)=0.40 1. If Route 2 is open during a snow storm, find the prob. that Route 1 is also open. 2. If Route 2 is closed during a severe snow storm, find the probability that Route 1 is also cl

Suppose that in between surf sessions on Oahu, you decide to try scuba diving with a group of friends. During the dive, you come across a sunken pirate ship. Amongst the ruins of the ship, a bottle contains the following list of directions along with a map to a treasure on the island of Kahoolawe. The directions and the map read as follows: Upon traveling to Kahoolawe, you and your friends believe that you have found the red rock and the highest hill in the vicinity, but the “tallest palm tree” had long since fallen and disintegrated. You realize that the treasure must be located on a circle with radius 50 “paces” centered around the red rock, but decide against digging a trench 942 feet in circumference, especially with no assurance that the treasure is still there. (Note that a “pace” is about a yard.) a.) Determine a plan to locate the position of the lost palm tree. Get creative here but try to use your new found trig abilities. b.) Using Law of Sines, find the angle…
suppose Gabe , an elementary school student , has just finished dinner with his mother , judy. Eyeing the nearby cookie jar, Gabe asks his mother if he can have cookie foe dessert. She tells Gabe that she needs to check his backpack to make sure that he finished his homework. Gabe cannot remember where he left his backpack, but he knows for sure that he did not complete his homework and will not be allowed to eat a cookie. Gabe believes his only option is to quickly steal a cookie while his mother is out of the room. Judy then leaves the room to look for Gabes backpack. Assume that judy could return at any time in the next 60 seconds with equal probability . For the first 20 seconds, Gabe sheepishly wonders if he will get caught trying to grab a nearby cookie. After waiting and not seeing his mother , Gabe decides that he needs a cookie and begins to take one from the jar. Assuming it takes Gabe 30 seconds to grab a cookie from the jar and devour it without a trace, what is the…
A twenty-something single person is planning a ski vacation. Assume that he has 2 possible destinations: Utah, and Oregon. There are 4 ski areas in Utah with 4 available times for 3 of the areas, and 1 times for the other area. There are 4 ski areas in Oregon with 2 available times for 3 of the areas, and 4 times for the other area. (A "time" refers to a weekend for which there are vacancies at the ski lodge.) A trip plan involves the selection of a location, ski area, and a time. How many possible plans are there?
1. A retail store stocks two types of shirts A and B. These are packed in attractive cardboard boxes. During a week the store can sell a maximum of 400 shirts of type A and a maximum of 300 shirts of type B. The storage capacity, however, is limited to a maximum of 600 of both types combined. Type A shirt fetches a profit of Php 20.00 per unit and type B a profit of Php 50.00 per unit. How many of each type the store should stock per week to maximize the total profit? Formulate a mathematical model of the problem.
An emergency vehicle can take one of two routes from a given site to the hospital immediately after a strong rainstorm. The region is crossed by creeks that tend to flood during rainstorm events. Route A would take 20 minutes, but it has four creek intersections where the road can flood, and each time that the emergency vehicle needs to cross a flooded road there is a 5-minute delay. Route B is longer and would take 35 minutes, but it has only two creek intersections where the road can flood. Assume that the probability of flooding after the rainstorm event at any of those creek

The Instant Paper Clip Office Supply Company sells and delivers office supplies to companies, schools, and agencies within a 50-mile radius of its warehouse. The office supply business is competitive, and the ability to deliver orders promptly is a big factor in getting new customers and maintaining old ones. (Offices typically order not when they run low on supplies, but when they completely run out. As a result, they need their orders immediately.) The manager of the company wants to be certain that enough drivers and vehicles are available to deliver orders promptly and that they have adequate inventory in stock. Therefore, the manager wants to be able to forecast the demand for deliveries during the next month. From the records of previous orders, management has accumulated the following data for the past 10 months: Month Jan. Feb. Mar. Apr. May Jun. Jul. Aug. Sep. Oct. Orders 145 70 115 85 120 54 82 141 123 94 Compute the mean…
Epsilon Airlines services predominately the eastern and southeastern United States. A vast majority of Epsilon's customers make reservations through Epsilon's website, but a small percentage of customers make reservations via phone. Epsilon employs call-center personnel to handle these reservations along with any problems with the website reservation system and for the rebooking of flights for customers if their plans change or their travel is disrupted. Staffing the call center appropriately is a challenge for Epsilon's management team. Having too many employees on hand is a waste of money, but having too few results in very poor customer service and the potential loss of customers. Epsilon analysts have estimated the minimum number of call-center employees needed by day of week for the upcoming vacation season (June, July, and the first two weeks of August). These estimates are given in the following table. Day Minimum Number ofEmployees Needed Monday 80 Tuesday 60 Wednesday…
You may recall that in recent National Football League history, Tom Brady and the New England Patriots were accused of deliberately deflating footballs in order to give themselves a competitive advantage on the football playing field. Presumably, one advantage of playing with a deflated football is that the ball is easier to grip...not only for the quarterback but for everyone who touches it. If the ball is easier to grip, players would fumble it less often. So, one way to examine if the Patriots actually had a competitive advantage due to deflated footballs is to compare their rate of fumbles with the rates of other NFL teams. It is important to note that prior to 2007, teams were not permitted to prepare their own footballs before a game-so it was only after that time that such an advantage should be observed -if there actually was such an advantage. Below, are the actual fumble rates for the 23 NFL teams who, like the Patriots, play in a NON-domed stadium where weather conditions…
The king is planning a new rectangular courtyard in his palace. It will be laid out using square tiles. He has chosen some very pretty, but very inexpensive, tiles. However, his adviser has informed him that some of the tiles will have to be a more expensive type. This is because visiting dignitaries will always walk along a certain diagonal, from one corner of the courtyard to the opposite corner, so the tiles along this diagonal will get lots of wear and tear. Every tile that contains a segment of the diagonal must thus be an extra-strength, more expensive tile. If a tile touches the diagonal only at a corner, it can be a regular tile. The diagram shows what the situation would look like if the king made a 4-by-6 courtyard. In this case, 8 tiles (shaded darker than the rest) include some portion of the diagonal, so these would need to be the more expensive kind. 1. The king wants to know how many of these special tiles to order. At the moment, he is planning a 63-by-90 tile…
