3. assume the following rules of associativity and precedence for expressions: precedence highest to lowest *, / +, –, & , mod – (unary) =, /=, < , < =, > =, > and associativity lowest left to right show the order of evaluation of the following expressions by parenthesizing all subexpressions and placing a superscript on the )to indicate order. for example, for the expression a + b * c + d the order of evaluation would be represented as ((a + (b * c)1 ) 2+ d)3 a. a * b - 1 + c b. a * (b - 1) / c mod d c. (a - b) / c & (d * e / a - 3) draw parse trees for the these expressions

Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate for the data below. internet speed levels of "fast comma " "medium comma " and "slow" choose the correct answer below. a. the ordinal level of measurement is most appropriate because the data can be ordered comma but differences left parenthesis obtained by subtraction right parenthesis cannot be found or are meaningless. nothing nothing nothing nothing nothing b. the interval level of measurement is most appropriate because the data can be ordered comma differences left parenthesis obtained by subtraction right parenthesis can be found and are meaningful comma and there is no natural starting point. c. the nominal level of measurement is most appropriate because the data cannot be ordered. nothing d. the ratio level of measurement is most appropriate because the data can be ordered comma differences left parenthesis obtained by subtraction right parenthesis can be found and are meaningful comma and there is a natural starting point.
