The set of polynomials is closed under the operation of multiplication.
A: Which equations illustrate this concept?
B: Which statements correctly explain this concept?
There may be more than one correct answer for each question. Select all correct answers for each question.
B: The sum of the polynomials (x2β3x+1) and (6x+2) is a polynomial, x2+3x+3, which shows there is closure under multiplication.
B: The sum of the polynomials (xβ3) and (x+2) is a polynomial, 2xβ1, which shows there is closure under multiplication.
B: The product of the polynomials (x2β3x+1) and (2x+2) is a polynomial, 2x3β4x2β4x+2, which shows there is closure under multiplication.
A: (xβ3)+(x+2)=2xβ1
A: (x2β3x+1)+(6x+2)=x2+3x+3
A: (x2β3x+1)(2x+2)=2x3β4x2β4x+2
A: (x2β3x+2)(x+5)=x3+2x2β13x+10
A: (3x+4)β(8x+2)=β5x+2
B: The difference of the polynomials (3xβ4) and (8x+2) is a polynomial, β5x+2, which shows there is closure under multiplication.
B: The product of the polynomials (x2β3x+2) and (x+5) is a polynomial, x3+2x2β13x+10, which shows there is closure under multiplication.

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)
