Use universal instantiation or universal modus ponens to fill in a valid conclusion for the following argument. ∀ real numbers r, a, and b, if r is positive, then (ra)b = rab. r = 3, a = 1 2 , and b = 6 are particular real numbers such that r is positive. ∴ (−3)1/2 6 = (−3)(1/2)(6) 31/2 6 ≠ 3(1/2)(6) 31/2 6 = 3(1/2)(6) 1 2 3 6 = 13 26 (−3)1/2 −6 = (−3)(1/2)(−6)

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

answer: i'm great at algebra

step-by-step explanation:

my best guesses would have to be either 4.5 or 2. p.s. if they're wrong, i'm so sorry for giving you the wrong answer.
