Let A = {x1, x2, . . . , x8} be a set of 12 positive integers, not necessarily distinct, such that xi ≤ 150, 1 ≤ i ≤ 12. Prove that there are at least two different 6-element subsets S1 and S2 of A such that the sum of the elements in S1 is equal to the sum of the elements in S2.

for b its (t) and c its (d)

step-by-step explanation:

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 expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

won't that be plagrisim thought?
