Jack's mother gave him 50 chocolates to give to his friends at his birthday party. he gave 3 chocolates to each of his friends and still had 2 chocolates left.

50 = 3x + 2

50 - 2 = 3x

48 = 3x

48/3 = 3x/3

16 = x

Jack has 16 friends.

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.

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
