reading‚ and we estimate the next digit to be zero. Our reading is reported as 9.20 cm. It is accurate to three significant figures. Rules for Zeros If a zero represents a measured quantity‚ it is a significant figure. If it merely locates the decimal point‚ it is not a significant figure. Zero Within a Number. In reading the measurement 9.04 cm‚ the zero represents a measured quantity‚ just as 9 and 4‚ and is‚ therefore‚ a significant number. A zero between any of the other

NUMBER SYSTEMS TUTORIAL Courtesy of: thevbprogrammer.com Number Systems Number Systems Concepts The study of number systems is useful to the student of computing due to the fact that number systems other than the familiar decimal (base 10) number system are used in the computer field. Digital computers internally use the binary (base 2) number system to represent data and perform arithmetic calculations. The binary number system is very efficient for computers‚ but not for humans.

3. Determine the class size. b. Range/number of classes. Example: 16/5=3.2; since the data don’t possess any decimals‚ the answer should be 3 to make it an odd number as well. Note: if the given data don’t possess decimals‚ the class size doesn’t have decimals as well. The class size is always an odd number. The number of decimal places depend on the number of decimal places of the given data. Table 2: Number of times in a month a respondent has entertainment activity. (MS Excel)

Exercise 18 Q1. Assuming that the distribution is normal for weight relative to the ideal and 99% of the male participants scored between ( - 53.68‚ 64.64)‚where did 95% of the values for weight relative to the ideal lie? Round your answer to two decimal places. Answer: Mean of weight relative to ideal = 5.48 and Standard Deviation (σ) = 22.93. Calculation: (x bar) 1.96(σ) 5.48± 1.96(22.93) 5.48 - 1.96(22.93) = 5.48 - 44.94 = (-39.46) 5.48 + 1.96(22.93) = 5.48 + 44.94 = 50.42 Expressed as (-39

In a percent‚ the decimal point would come at the end of the last number (for 75%‚ envision that it looks like 75.) Examples: 75% converts to .75 40% converts to .40 3.1% converts to .031 ✔Changing decimal or whole number to percent Change a decimal to a percent. Move the decimal point two places to the right.
