Number stairs
Maths coursework Number stairs The number stairs coursework involves using a 10x10 numbered grid up to 100 using this grid, i will draw on step shapes the step shapes that will be created overlap the numbers in the grid. The overlapped numbers will be added up to create a total figure this is the number i am trying to work towards. The formula created will have to be formed to calculate the total from using the bottom left hand number on the stair shape. Algebra will be a major part of this coursework as it is needed to create the formula. The algebra can be used to replace the numbers in the formula. The final formula i predict will require the numbers of steps and the bottom left number. st objective - collect data form patterns convert to algebra for a 10x10 grid convert to formula test formula 2nd objective- vary size of step stairs and modify formula accordingly 3rd objective- vary size of grid try an increase to 10x15 and test formula formula must use algebra and be able to produce the answer of total sum without the use of the diagram apart from the number of stairs and the number of the bottom the bottom left square. This number will be called n in the

The Gradient Function
The Gradient Function Introduction: In this investigation I am going to investigate the gradient function of different lines. I am going find out the gradient of each line and then look at all the different gradients. With these different gradients I am going to comment on the difference of the value of the different gradients. Observations: I can see that the gradients have got bigger, the bigger the line. For example: THE AVERAGE GRADIENT OF y = x is 1 THE AVERAGE GRADIENT OF y = x (3 is 9 I can see that each 3 gradients on each line are positive on the lines of y = x (3 y = x (3 GR 18 GR 8 GR 1 y = 2x (3 GR 32 GR 28 GR 2 y = 3x (3 GR 40 GR 54 GR 3.25 While lines of y = x (2 most of them have negative gradients y = x GR -2 GR -0.8 GR 4 y = 2x (2 GR -14 GR -3 GR 13 y = 3x (2 GR -45 GR 33 GR 27.5 Formula: The formula is gr = a Conclusion: I have found out that gradients increase when the line is made bigger. Also I have commented on different observations I have
Investigation to find if there is a difference in word length between an American news paper and a British paper
The written word Introduction: Aim to find if there is a difference in word length between an American news paper and a British paper. I chose 2 political articles that are about the same and systematically chose 66 words from each article by selecting every 5th word using statistical analysis. Here are all the words that I chose from the American paper and the British paper: USA Today Mail on Sunday Is Cabinet Efforts Majesty Of At Experts Eye That Ostensibly A During Overthrow Domestic Ruled And Two Considered House Relaunch Confirm Into Is Considered CIA And Have Their Area Public British Been Our Whole Administration Exotic Than The The Even An On That Israeli The New Increasing A National Of Whose A The United Provide In Official Lobbying Will Against To There Convene Of Detectors Hussein Or American They Decide Hundred Wholesale Serving Is The Threat Other After Of This Troops Surprise If After If Merly It Of Among Pentagon Saudi The A A Further
For my mathematics coursework I have chosen to study T-shapes
For my mathematics coursework I have chosen to study T-shapes. T-shapes consist of a group of squares, shaped like a T, positioned on a numbered grid. An example of such a T-shape is below. The area outlined in red is the T. It is three squares horizontally and three squares vertically, making it a 3x3 T. The grid is a vertical eight squares and an horizontal eight squares on the grid, making it an 8 x 8 square. The sum of all the grid squares across which this T is plotted is the T total. The first square of the T, outlined in green, is called T for purposes of calculating the T total. In this T-shape, T = 1. Calculation of the T-total: +2+3+10+18 = 34 T+T+1+T+2+T+9+T+17 = 5T + 29 This shows us that the formula for a 3x3 T plotted from T1 on an 8x8 grid is 5T + 29. I predict that this formula may apply for any 3x3 T in this grid. I will now investigate this by plotting 3x3 T-shapes originating in other parts of the grid.

Maths borders
This is my math's project, where you are tested on your pattern, sequence and algebra. This project is called 'Borders' I have answered the questions on the answer sheet. a) For question 1b) I was asked to draw a table to show my findings, in this way I put it in order, in columns, and wrote extra information, like cross shape 1 and 2, so that the sequence could be more understandable. b) Total = W+G (T) Num. of Grey Squares (G) Num. of White Squares (W) Shape Number. 5 4 Cross shape 1 3 5 8 Cross shape 2 25 3 2 Cross shape 3 c) The pattern is: That to find out the number of white squares in the shape, you multiply the number of Cross shape, (I.e. shape 1, 2, 3, 4...) By 4, the formula is:
Business Report part 6 (graph1)
Graphs The graph shows that there are more females than males. This graph shows the amount of people who carry a mobile. Most people carry a mobile. This is a good sign as we know that people in that area are used to mobiles. This graph shows the model or brand people would like to buy if they were considering buying one. From my results I could clearly see that Nokia is a popular type of mobile. This graph shows the maximum amount people would spend on a mobile phone. Most people choose £100-£200. This is a good result because of course any customer would want a good mobile and the staff can provide them with a mobile to their satisfaction because most mobiles are available in this
