Part 1: Data Analysis
The data that will be analyzed in this report is the consumer price index for fuel prices from the year 1982 to 2011. In this report we will be analyzing trend of gasoline prices and were they will take us in the future. Also this report will be help companies dealing with the oil industry and the expected price increases from a statistical perspective.
Scatterplot:
This chart shows us over time (x-axis) and the average price of fuel (y-axis) per year and explains the rate at which fuel prices are increasing. Without outside variables we can easily see the correlation of fuel prices now and what they will be in the future.

The graph shows there is a positive correlation between price and time. The regression line and the positive slope explains that positive correlation.
The slope:
The slope as indicated by that diagram is .065, the value represents that the fuel price will increase over time, if the all assosiated variables are constant, by .065 units. So all of this information explains the increase in fuel prices as time elaspses.
The y intercept:
The y intercept from the results is -127.643.
Regression model: y = 0.065x - 127.643
Estimating Fuel prices for 2020:
When estimating fuel for 2020 within the model we are using we simply have x equal the year to come to the conclusion of where fuel prices will be. If the fuel price rises on average .065 units per year then in 2020 the outcome is easy to calculate.
When the year is 2020, x = 2020. fx=0.065x-127.643 f(2020)=0.0652020-127.643
=131.3-127.643
=3.657
From the results, the estimated price in the year 2020 will be $3.657
I thinkthis estimation is a bit low unless fuel prices level like they did for 1982 to 2001 lets hope so.

Vision 2020

...Wawasan 2020 or Vision 2020 is a malaysian ideal introduced by the former Prime Minister of Malaysia, Mahathir bin Mohamad during the tabling of the Sixth Malaysia Plan in 1991. The vision calls for the nation to achieve a self-sufficient industrialized nation by the year 2020, encompasses all aspects of life, from economic prosperity, social well-being, educational worldclass, political stability, as well as psychological balance. In order to achieve Vision 2020, Mahathir lamented that the nation required an annual growth of 7% (in real terms) over the thirty-year periods (1990–2020), so that the economy would be eightfold stronger than its 1990 GDP of RM115 billion. This would translate to a GDP of RM920 billion (in 1990 Ringgit terms) in 2020.Wawasan 2020 is also the title of an article by William Greider about globalization in Malaysia.Mahathir had outlined nine strategic challenges that Malaysia must overcome to achieve Vision 2020. The first challenge is establishing a united Malaysian nation made up of one Bangsa Malaysia (Malaysian Race). The second challenge is creating a psychologically liberated, secure and developed Malaysian society. The third challenge is fostering and developing a mature democratic society. The fourth challenge is establishing a fully moral and ethical society. The fifth challenge is establishing a matured liberal and tolerant society. The sixth challenge is establishing a scientific and progressive society. The seventh challenge is establishing...

Wawasan 2020

...So, what is Vision 2020? The Vision 2020 was developed to be a long-term goal for the nation, the goal of Malaysia becoming a “fully developed country” by year 2020 (The Mahathir Years, 2009). In other words, by the year 2020, Malaysia can be a united nation, with a confident Malaysian society, infused by strong moral and ethical values, living in a society that is democratic, liberal and tolerant, caring, economically just and equitable, progressive and prosperous, and in full possession of an economy that is competitive, dynamic, robust and resilient (Wawasan 2020, nd). However, the Vision 2020 equires the Malaysian economy to grow at 7.0% per annum. The 9th Malaysia Plan envisages an annual growth of 6.5%, while the Third Industrial Master Plan targets 6.3% growth for the plan period (Gregore Pio Lopez, nd). Also, Malaysia could not be fully developed until Malaysia has finally overcome the nine central strategic challenges that have confronted us from the moment of our birth as an independent nation. According to Wawasan 2020, it is to be said that one of the challenges of achieving Vision 2020 will be establishing establishing a united Malaysian nation with a sense of common and shared destiny. This must be a nation at peace with itself, territorially and ethnically integrated, living in harmony and full and fair partnership, made up of one 'Bangsa Malaysia' with political loyalty and dedication to the nation. For instance, this can be seen in the big gap between Malay...

The whale has displaced a greater mass of water at the depth, so the buoyant force is greater. 20. Ice cubes float in water, and sink in alcohol. Anything with less density than the liquid that it's in will float. 22. It will increase 35. It would be harder on the top of a mountain because the pressure of the atmosphere is lower the higher you go.

...begin to form on the outside of the jar will vary depending on the environmental conditions where the experiment is taking place. Observation At what point did you start to see water droplets? Can you explain what's happening? How could the water droplets be forming on the OUTSIDE of the jar when the ice is on the INSIDE of the jar, and the cap is screwed on tight? Where have you seen other natural occurrences of condensation? (here's a hint... think of what's on the ground on a cold morning). Result The salted ice quickly makes the sides of the glass jar very cold. As the water that exists in the air as a gas hits the cold sides of the jar, it changes into a liquid! This process is known as condensation, which is the opposite of evaporation. There is water in the air at all times, but we don't see it since it's in a gaseous state. Our experiment turns the gas into a liquid, allowing us to physically see the...

...dissolved oxygen would be higher in the stream because of its moving water. The temperature in the wetland will be higher because the sun is directly on it. Testing six tubes from both the wetland and the stream, findings show the temperature did indeed prove to be higher in the wetland. However, the dissolved oxygen level was higher in the wetland as opposed to the stream. INTRODUCTION: pH is the level of concentration from Hydrogen ions within a substance. It is usually measured to determine how much aquatic life can be supported within an environment (Metro 1990). Along with having the correct amount to Hydrogen ions, both the stream and the wetland have a level on dissolved oxygen level. This level is measured to the amount of oxygen gas bubbles within the water that the aquatic life uses to sustain itself. This oxygen is also used to decompose of organic matter (Metro 1990). The purpose of this experiment is to test to determine to what levels of both pH and dissolved oxygen are processed by the stream and wetlands. . It was predicted that the dissolved oxygen would be higher in the stream because of its moving water. The temperature in the wetland will be higher because the sun is directly on it. METHODS/MATERIALS: Thirty-six test tubes were labeled with masking tape in order to differ between the wetland being tested and the stream being tested. Eighteen test tubes are labeled “Stream” and the other eighteen are labeled “Wetlands”. Separate the test tubes to test tubes...

...of equipment and materials: * 500mL beaker * Bunts & Burner * Thermometer Description of how to control and measure the variables: * Room Temperature: The set room temperature in a room is most likely able to be controlled with the system. Room temperature is usually around 20°C. * Surface Area: The 500mL beaker is significant because if the surface area of the beaker is larger or smaller, than the results of the experiment will be incorrect due to the different volume of water. * Temperature (100°C): It is important to acknowledge that the temperature at which water boils is 100°C. This is controlled by how much gas and fire is released from the Bunts & Burner. * Time (seconds): The time is highly important. Time is controlled by how much gas is released from the Bunts & Burner. The lower the gas, the longer it will take for the water to boil due to low heat. SCOPE AND LIMIT The range of your measurements (from x to y) and the size of the increments within this range; I will vary the temperature between 20°C and 100°C (boiling point) in steps of 10°. Repeated measurements, average, etc. I will measure the time for the beaker with different amounts of water each trial time it drops 100mL and then I will find the average time for each trial. Next I will divide the average by 10 to find the average period. DATA AND PROCESSING What data are you going to collect? Sketch a relevant table...

The characteristic of the crack follows a sinusoidal crack path with hackle marks that indicate the direction of the crack in the longitudinal crack path. Often times a crack may split in to more than one branch. Figure #2: URCP Crack Historical Issues As mentioned previously since the use of PE tubes & pipes has been a large part of the industry, the URCP phenomenon is becoming a more and more common problem in the industry. Over the course of a couple of decade the following issues have been documented. * In October 1985, an incident related to URCP occurred in a PE gas system which was reported in Szeged (Hungary) over a length of 700 m. Other long running cracks were also observed on the tubes & pipesline system. The crack was initialed at the time of installation. * In 1989, an incident occurred in Antwerp (Belgium), a rapid crack occurred in a PE water tubes & pipesline system. The crack...

...reactions over a long period of time. You should never allow the top of the condenser to be stoppered because if you attempt to heat sealed glass apparatus it may explode. Also, you should heat gently because there is a huge risk, when not heated gently, of the equipment exploding and breaking. Also, heating under gentle reflux means the solution can vaporise correctly. Distillation Distillation is when you purify a liquid by a process of heating and cooling. Water enters at the end of the tube. The thermometer is placed inside the distilling flask. Anti-bumping granules are used to provide many places where bubbles of gas may form as the water boils. The bubbles are small and rise steadily to the surface of the liquid where they burst. Without the granules, fewer but larger bubbles form. They rise and burst with such force that they shake the test tubes which can be a hazard. Recrystallisation We recrystallise in order to purify chemicals. In order to recrystallise, we first have to add a small quantity of appropriate solvent to an impure solid. Then we have to apply heat to dissolve the solid. After this, we have to cool the solution to crystallize the product. Finally we use a vacuum filtration to isolate and dry the purified solid. Melting point We use this to determine whether...

...or removed from a substance and how to calculate the enthalpy change. Answer In a gas, the potential energy (energy of attraction) is small to the kinetic energy thus, on average, the particles are far apart. This large distance has several macroscopic consequences : a gas fills its container, is highly compressible, and flows easily through another gas. In a liquid , attractions are stronger because the particles are touching, but they have enough kinetic energy to move randomly around each other.Thus, a liquid conforms to the shape of its container but has a surface ; It resists an applied force and thus compresses very slightly ; and it flows, but much more slowly than gases. In a solid, the attractions dominate the motion so much that the particles are fixed in position relative to one another, just jiggling in place. Thus, a solid has its own shape, compresses even less than liquids, and does not flow significantly. Each phase change has a name and an associated entalphy change : Gas to liquid, and vice versa. As the temperature drops, the molecules in the gas come together and form a liquid in the process, changing from a liquid to gas, is vaporization. Liquid to solid, and vice versa. As the temperature drops further, the particles move slower and become fixed in position in the process of freezing ; In common speech, freezing implies low temperature because we thin of water.

Evaluation of Kohlberg's Theory of Moral Development

...Solubility is the property of a solid, liquid, or gaseous chemical substance called solute to dissolve in a solid, liquid, or gaseous solvent to form a solution of the solute in the solvent Solubility is defined as the ability of one substance to dissolve within another substance. What Affects Solubility? One of the factors that has a profound impact on solubility is temperature. Temperature, a measure of the available thermal energy, can increase the solubility of solids in liquids. This phenomenon can be observed in the creation of supersaturated solutions, or mixtures that contain far more of the solid dissolved in a liquid than would be possible under room temperature conditions. One application of supersaturated solutions can be seen in the production of rock candy where high-temperature sugar solutions readily form sugar crystals on the surface of objects placed in the solution. For gases that are dissolved in liquids, however, the trend is just the opposite. Cooler temperatures increase the solubility of gases in liquids, and higher temperatures decrease the solubility of gases. An example of the effect of temperature on dissolved gases can be found in the loss of dissolved oxygen in lakes or streams during extremely hot weather, a condition that results in the death of fish. In physical chemistry, saturation is the point at which a solution of a substance can dissolve no more of that substance and additional amounts of it will appear as a separate phase (as a...
