the data from before created a graph. Using the graph‚ get the best-fit straight line to examine the relationship. Using the predicative model (the best-fit line) to determine the percent copper and zinc in pennies. Then accuracy the errors and error percentages. Precision the absolute deviation and the deviation percentages. Observation: Part 1: Pre-82 Pennies Weight 10 dry pre-82 pennies which get 30.29g‚ using 30ml initial volume measuring the volume of 10 pennies‚ record the data 3.0ml

What Do Mathematics and Being a Math Teacher Mean to Me? Mathematics‚ for me‚ is a science of systematic way of thinking. Symbols (e.g. numbers) are meant for representation‚ accuracy and precision. Mensuration‚ which is very useful both in practical purposes and other sciences‚ is a great example as proof. Manipulation of these symbols produces systematic representation and pattern. For an instance‚ an individual who is good in constructing‚ determining‚ and manipulating equations as well as inequalities

We must work in the 35% to 100% volume range for best accuracy and precision . Besides that ‚ the tip immersion angle also plays an important role . Nextly‚ the micrometer setting must be done using the correct technique . If filled ‚ we should not lay the pipette down or hold more than 20º from vertical . Lastly
