x Biology 11 Ms. Zwart 06.09.13 The Cooling Curve of Water Variables: Independent Variable: The independent variable is heat; we measure the temperature with a thermometer‚ which has a systematic error of ± 0.5 °C. Dependent Variable: The dependent variable is time; we know when 30seconds pass with the use of a stopwatch‚ which has a systematic error of ± 1 second. Controlled Variables: The controlled variables used in this experiment are; a 400ml beaker with the systematic error

Kyoto´s Protocol signed by European Countries in 1997 made Eurozone commits itself to reducing their CO2 emissions by 5% (referred to 1990 figures) [1]. In order to achieve such a reduction all countries were forced to their own abatement figures and also to incorporate environmental policies to their legislations. The EU Commision´s 2007 and 2008 communications and proposals were the basis of Directive 2009/28/EC where Strategy 2020 was established. The basic core of this strategy is 20/20/20:

PRODUCTION POSSIBILITIES CURVE: A curve that illustrates the production possibilities of an economy--the alternative combinations of two goods that an economy can produce with given resources and technology. A production possibilities curve (PPC) represents the boundary or frontier of the economy’s production capabilities‚ hence it is also frequently termed a production possibilities frontier (PPF). As a frontier‚ it is the maximum production possible given existing (fixed) resources and technology

1. Suppose there are 100 consumers with identical individual demand curves. When the price of a movie ticket is $8‚ the quantity demanded for each person is 5. When the price is $4‚ the quantity demanded for each person is 9. Assuming the law of demand holds‚ which of the following choices is the most likely quantity demanded in the market when the price is $6? Explain and show calculations‚ While the question asks of the choices given what the quantity demanded will be‚ there are no choices

bell curve is literally‚ the symmetrical curve created on a graph when using a frequency distribution method for a set of data‚ splitting the mean symmetrically. There is a big difference between standard deviation and the bell curve! Standard deviation shows the difference in variation from the average; the bell curve‚ also normal distribution or Gaussian distribution‚ shows the standard deviation and is created by the normal or equal distribution of the mean among either half. The bell curve is an

ECON 1. (Demand Under Perfect Competition) what type of demand curve does a perfectly competitive firm face? Why? A horizontal or a perfectly elastic‚ demand curve. A perfectly competitive firm is called a price taker because that firm must “take‚” or accept‚ the market price- as in “take it or leave it.” 2. Explain the different options a firm has to minimize losses in the short run. A firm in perfect competition has no control over the market place. Sometimes that price may be so low
