It is extremely important for a researcher to clearly define the variables in a study because this helps to determine the type of analysis that can be performed on the data. for example, if a researcher wanted to describe countriescountries based on isbn left parenthesis international standard bookisbn (international standard book number right parenthesis group identifiernumber) group identifier, what level of measurement would the variable "isbn group identifierisbn group identifier" be? now suppose the researcher felt that certain countries who were farthercountries who were farther northnorth received higher identifying numbersidentifying numbers. does the level of measurement of the variable change? if so, how?

Five times the sum of a number and 27 is greater then or equal to six times the of that number and 26. what is the solution set to this proportion?

Suppose that jim plans to borrow money for an education at texas a& m university. jim will need to borrow $25,000 at the end of each year for the next five years (total=$125,000). jim wishes his parents could pay for his education but they can’t. at least, he qualifies for government loans with a reduced interest rate while he is in school. he has a special arrangement with aggiebank to lend him the money at a subsidized rate of 1% over five years without having to make a payment until the end of the fifth year. however, at the end of the fifth year, jim agrees to pay off the loan by borrowing from longhorn bank. longhorn bank will lend him the money he needs at an annual interest rate of 6%. jim agrees to pay back the longhorn bank with 20 annual payments and the payments will be uniform (equal annual payments including principal and interest). (i) calculate how much money jim has to borrow at the end of 5 years to pay off the loan with aggiebank. a. $121,336 b. $127,525 c. $125,000 d. $102,020 e. none of the above

Henry crouch's law office has traditionally ordered ink refills 55 units at a time. the firm estimates that carrying cost is 35% of the $11 unit cost and that annual demand is about 240 units per year. the assumptions of the basic eoq model are thought to apply. for what value of ordering cost would its action be optimal? a) for what value of ordering cost would its action be optimal?
