environmental issues and economic performance and population density Executive summary The main goal with the report was to analyse the relationship from 16 different countries on how‚ if any‚ CO2 emission per capita is getting affected by population density and GDP per capita by using descriptive statistics and regression. The conclusion is that CO2 emission per capita is affected by changes in GDP per capita and that population density has no significant relation to CO2 emission per capita.

conditions; low‚ medium‚ and high density. The effects of different population densities on the survivorship and reproduction of Daphnia are observed over a two-week period within a lab environment. Over the two week period‚ the numbers of parent Daphnia alive and dead are recorded daily‚ along with the amount of offspring produced each day. From the main parameter investigated‚ the net reproductive rate‚ the results of the experiment support that higher densities result in less successful reproduction

The cumulative density function - CDF of the dual EGC output signals and the joint of output signal and its the first time derivative is determined. The probability density function -PDF of the dual EGC output signals and the joint of output signal and its the first time derivative is determined. Keywords – EGC‚ PDF‚ CDF‚ Fading‚ Rayleigh

Random Variable and Its Probability distribution “A random variable is a variable hat assumes numerical values associated with the random outcome of an experiment‚ where one (and only one) numerical value is assigned to each sample point”. “A random variable is a numerical measure of the outcome from a probability experiment‚ so its value is determined by chance. Random variables are denoted using letters such as X‚Y‚Z”. X = number of heads when the experiment is flipping a coin 20 times. There

Hong Kong Housing Problem is not only attributed to the High Population Density Every Hong Kong citizen knows one of the grave troubles in Hong Kong is housing problem. The order of severity can be apparently reflected by many figures in recent research studies. ”Rents up 22 per cent in Hong Kong“ (2011) remarks that “the price of renting two-bedroom accommodation rose by 22% to US$2‚830 a month between 2009 and 2010“ (¶2).
