CLEP General Mathematics: Percentage And Measurement

Subjects : clep, math, measurement
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The accuracy of a measurement is often described in terms of the number of






2. Percentage divided by base






3. The maximum probable error is found when the denominator of the fraction expressing the error ratio is divided into the numerator or






4. Percent is used in discussing






5. Depends upon the relative size of the probable error when compared with the quantity being measured.






6. The extra digit protects the answer from






7. Can be a significant digit if it is not the first digit in the number because it is a part of the number specifying how many hundredths are in the measurement.






8. The precision of a number resulting from measurement depends upon






9. To find the percentage of a number - multiply the base by the rate. The rate must be changed from a percent to a decimal before multiplying can be done.






10. The maximum probable error is






11. The 'of' has the same meaning as it does in fractional examples - such as 1/4 of 16 = ?






12. A rule that is often used states that the significant digits in a number






13. A larger number of decimal places means a smaller






14. Drop the percent sign and divide the number by 100. Mechanically - the decimal point is simply shifted two places to the left and the percent sign is dropped.






15. To flnd the bue when the rate and percentage are known






16. FRACTIONAL PERCENTS.-A fractional percent represents a part of 1 percent.






17. Form the basis for the rules which govern calculation with approximate numbers (numbers resulting from measurement).






18. Is the part of the base determined by the rate.






19. Before adding or subtracting approximate numbers - they should be






20. To change a decimal to percent multiply the decimal by 100 and annex the percent sign (%). Since multiplying by 100 has the effect of moving the decimal point two places to the right - the rule is sometimes stated as follows:






21. To add or subtract numbers of different orders






22. One-thousandth of an inch. One-thousandth of an inch is about the thickness of a human hair or a thin sheet of paper.






23. Experience has shown that the best the average person can do with consistency is to decide whether a measurement is more or less than halfway between marks. The correct way to state this fact mathematically is to say that a measurement made with an i






24. It is important to realize that precision refers to






25. Closely associated with the study of decimals is a measuring instrument known as a micrometer.






26. In order to multiply or divide two approximate numbers having an equal number of significant digits






27. Since hundredths were used so frequently - the decimal point was dropped and the symbol % was placed after the number and read

28. Common fractions are changed to percent by flrst expressmg them as






29. Deals with the group of decimal fractions whose denominators are 100-that is fractions of two decimal places.






30. To to find the percentage of a number when the base and rate are known.






31. May be considered as special types of decimals (for example - 4 may be written as 4.00) and thus may be expressed interms of percentage.






32. When it is necessary to use a percent in computation - to avoid confusion the number is written in its by first expressing it as a fraction with 100 as the denominator - Since percent means hundredths - any decimal may be changed to percent






33. It is possible to round off a repeating decimal at any desired point - the degree of precision desired should be determined and:






34. Relative error is usually expressed as






35. Relative error is the ratio between the _________________. This ratio is simply the fraction formed by using the probable error as the numerator and the measurement itself as the denominator.






36. Can never be more precise than the least precise number in the calculation.






37. Is the whole on which the rate operates.






38. The accuracy of a measurement is determined by the ________






39. In a number such as 49.30 inches - it is reasonable to assume that the 0 in the hundredths place would not have been recorded at all if it were not a






40. Is the number of hundredths parts taken. This is the number followed by the percent sign.






41. When a common fraction is used in recording the results of measurement






42. The base corresponds to the multiplicand - the rate corresponds to the multiplier - and the percentage corresponds to the product...We then divide the product (percentage) by the multiplicand (base) to get the other factor (rate).






43. The probable error in any measurement is how precisely the instrument is marked - The precision of a measurement depends upon






44. The word 'percent' is derived from Latin. It was originally 'per centum -' which means 'by the hundred.' Thus the statement is often made that 'percent' means






45. How many hundredths we have - and therefore it indicates 'how many percent' we have.






46. It can also be shown that the precision of a difference is no greater than the all numbers should first be rounded off to






47. There are three cases that usually arise in dealing with percentage - as follows:






48. How much to round off must be decided in terms of






49. To find the rate when the percentage and base are known






50. The precision of a sum is no greater than
