This portfolio is an investigation into how the median Body Mass Index of a girl will change as she ages. Body Mass Index (BMI) is a comparison between a person’s height (in meters) and weight (in kilograms) in order to determine whether one is overweight or underweight based on their height. The goal of this portfolio is to prove of disprove how BMI as a function of Age (years) for girls living in the USA in 2000 can be modeled using one or more mathematical equations. This data can be used for

Dasean Matheson 11/25/13 APES Ms. Sarameinto Population is the largest increasing factor in our world. This factor is the cause of many events in our world. Poverty hunger and war are just some of the immediate effects of increasing population. Among these extreme causes the less immediate events will be seen with air pollution‚ land degradation‚ which is the effect that’ll have the longest term effect on the world. But how can these events are avoided? Is there any hope of stopping this

Beverly Hearst IB SL Physics Rate of Vaporization Design Lab Research Question: How does changing the surface area of a sample of water affect the time taken for the water to boil? Background: By changing the containers of the water‚ the surface area of the water is thus being modified as the same volume of water is spread out over smaller or larger surfaces. The measure being compared is the time each sample of water will take before it reaches the boiling point‚ 100 C°. The relationship

Review Questions 1.7 1. Outline four ways in which the size of a market can be measured. Growth of a business refers to the expansion in size of its operations and this can be measured in several ways‚ including: * The value of the firm’s sales turnover (also known as the sales revenue) * The firm’s market share‚ i.e. the sales revenue of the business as a percentage of the industry’s sales * The value of the firm’s capital employed * The number of employees hired by the business
