The ice cream kiosk has a set of freezers for storing ice cream. If a freezer malfunctions, then Margaret needs to be informed. • The perfect temperature for storing ice cream is -18°C. • A permissible temperature tolerance is plus or minus one degree Celsius. • An output message must be displayed to show the number and temperature of any freezer falling outside tolerance. • The output message for each freezer must be on a single line. • No other messages should be displayed. • A global data structure holding the temperatures is provided and must be used as part of the solution. SET freezers TO [-20, -19, -18, -17, -16, 0, 1] • The solution should work even if the number of freezers in the data structure is changed. An example output is shown. Freezer 0 is out of tolerance: -20 Freezer 4 is out of tolerance: -16 Freezer 5 is out of tolerance: 0 Freezer 6 is out of tolerance: 1 Write an algorithm to inform Margaret if any of the freezers are faulty.

Which of the following methods could be considered a “best practice” in terms of informing respondents how their answers to an on-line survey about personal information will be protected? respondents are informed that investigators will try to keep their participation confidential; however, confidentiality cannot be assured. respondents are informed that a research assistant will transfer all the research data to a password-protected computer that is not connected to the internet, via a usb flashdrive. the computer is located in a research team member’s office. the investigator uses the informed consent process to explain her institution’s method for guaranteeing absolute confidentiality of research data. the investigator uses the informed consent process to explain how respondent data will be transmitted from the website to his encrypted database without ever recording respondents’ ip addresses, but explains that on the internet confidentiality cannot be absolutely guaranteed.

Ac++an of of pi. in , pi is by : pi = 4 – 4/3 + 4/5 – 4/7 + 4/9 - 4/11 + 4/13 - 4/15 + 4/17 . ., to pi (9 ). , if 5 to pi,be as : pi = 4 - 4/3 + 4/5 - 4/7 + 4/9 = 4 – 1. + 0.8 - 0. + 0. = 3.. atoofbe to pi?
