Which statement about the simplified binomial expansion of (a + b2)n, where n is a positive integer, is true? The exponent of b will always be even.
The exponent of a will always be odd.
The sum of the exponents of a and b will always equal n.
The sum of the exponents of a and b will always equal n – 1.

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.

the answer is: the length is 5/6 yards.
