CH 101 – WebAssign HW1 Spring 2008 Dr. Ison 1. /3 points | 2/5 submissions Last Response | Show Details All Responses Notes After you submit an assignment, WebAssign will show correct answers with green check marks and wrong answers with red x marks. However, I often turn the marks off for parts of certain questions because the number of submissions is greater than the number of choices. In those cases you will see no marks for those parts and you must check the Question Score to see how many points you missed. I have turned the marks off for this question, so select the Question Score link at the top of the assignment to see if you missed any part of the question. You won't know which part you missed, but you can tell how many parts you missed. WebAssign grades all numerical answers with a 1% tolerance, so all numerical answers should contain at least three significant digits. In addition, you will sometimes want to use the e-format for exponentials. For example, 2.53x10 12 would be expressed as 2.53e12. Express the following numbers to three significant digits in the e-format. Use one number to the left of the decimal and two to the right. Do not use preceeding zeros in the exponent, e.g. e-5 not e-05. 0.002342998 2.34e-3 0.0000471772 4.72e-5 15485552 1.55e+7 -or- 1.55e7 2. /6 points | 1/5 submissions Last Response | Show Details All Responses Notes No marks will be shown for this question.
