determine whether each statement is true/false, and justify answer.
a) suppose that a is an invertible n\times n matrix with integer entries. if det(a) = 1 , then a^{-1} also has integer entries.
b) if a is a square matrix, then (adj(a)) = adj (a^t)

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.

2160ft3

step-by-step explanation:

if you need , reply with more info. u.

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
