Math Sl Fish Production - 1358 Words

FISH PRODUCTION - MODELING The aim of this investigation is to consider commercial fishing in a particular country in two different environments, that is from the sea and a fish farm (aquaculture). The following data provided below was taken form the UN Statistics Division Common Database. The tables gives the total mass of fish caught in the sea, in thousands of tones (1 tone = 1000 kilograms). Year | 1980 | 1981 | 1982 | 1983 | 1984 | 1985 | 1986 | 1987 | 1988 | Total Mass | 426.8 | 470.2 | 503.4 | 557.3 | 564.7 | 575.4 | 579.8 | 624.7 | 669.9 | Year | 1989 | 1990 | 1991 | 1992 | 1993 | 1994 | 1995 | 1996 | 1997 | Total Mass | 450.5 | 379.0 | 356.9 | 447.5 | 548.8 | 589.8 | 634.0 | 527.8 | 459.1 | Year |†¦show more content†¦The principle axis is midway between the maximum and minimum, so d≈634.0+356.92≈495.45. So, the model is M≈138.75sin2Ï€9x-c+495.45 for some constant c. We can notice that the point A on the original graph, graph1, lies on the principles axis and so it is a point at which we are starting a new period. Since A is at (1989,450.5), c = 1989. The model is therefore M≈138.75sin2Ï€9x-1989+495.45 and we can superimpose it on the original data as follows. Graph5. Sin model The graph shows what happens when we fit the original graph , Graph4. with its model graph. The slopes of the two graphs are presented to be nearly equal at certain points. The model presents decreasing and increasing values. Points shown from year 1989 – 1991, 1995 – 1997, 1999 – 2000, 2002 – 2003, 2004 -2005 are decreasing, as for the rest of the years are increasing. The following table below presents the total mass of fish that were raised form the fish farm, in thousands of tones.
