Raptor Fuels produces three grades of gasoline Regular‚ Premium‚ and Super. All of these are produced by blending two types of crude oil Crude A and Crude B. The two types of crude contain specific ingredients which help in determining the octane rating of gasoline. The important ingredients and the costs are contained in the following table: [pic] .:. In order to achieve the desired octane ratings‚ at least 41% of Regular gasoline should be Ingredient 1; at least 44% of Premium gasoline must

Intro The emerald ash borer is an invasive wood boring insect that originated in Asia. The borer is believed to have crossed the Canadian and American border in the early 2000s by way of Windsor and Detroit (1). They have now infested much of Southern Ontario‚ as well as‚ in small parts of western Quebec (2). Emerald ash borers destroy ash trees by eating all the ash species in Ontario which include green‚ red‚ white‚ black‚ and ash trees. When beetles eat ash trees‚ they leave 4-5 millimeter holes

Introduction: Data analysis is an attempt by the researcher to summarize collected data either quantitative or qualitative. Generally‚ quantitative analysis is simply a way of measuring things but more specifically it can be considered as a systematic approach to investigations. In this approach numerical data is collected or the researcher transforms collected or observed data into numerical data. It is ideal for finding out when and where‚ who and what and any relationships and patterns between
