The set of polynomials is closed under the operation of subtraction.
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 difference of the polynomials (3xโ4) and (2x+2) is a polynomial, xโ6, which shows there is closure under subtraction.
A: (2x^2+2x+1)โ(x^2+xโ4)=x2+x+5
B: The product of the polynomials (x^2โ3x+1) and (2x+2) is a polynomial, 2x^3โ4x^2โ4x+2, which shows there is closure under subtraction.
B: The difference of the polynomials (2x^2+2x+1) and (x2+xโ4) is a polynomial, x2+x+5, which shows there is closure under subtraction.
A: (3xโ4)โ(2x+2)=xโ6
A: (xโ3)+(x+2)=2xโ1
B: The sum of the polynomials (xโ3) and (x+2) is a polynomial, 2xโ1, which shows there is closure under subtraction.
A: (x^2โ3x+1)(2x+2)=2x^3โ4x^2โ4x+2
B: The sum of the polynomials (3xโ4) and (8x+2) is a polynomial, 11xโ2, which shows there is closure under subtraction.
A: (3xโ4)+(8x+2)=11xโ2

(20 points) a bank has been receiving complaints from real estate agents that their customers have been waiting too long for mortgage confirmations. the bank prides itself on its mortgage application process and decides to investigate the claims. the bank manager takes a random sample of 20 customers whose mortgage applications have been processed in the last 6 months and finds the following wait times (in days): 5, 7, 22, 4, 12, 9, 9, 14, 3, 6, 5, 15, 10, 17, 12, 10, 9, 4, 10, 13 assume that the random variable x measures the number of days a customer waits for mortgage processing at this bank, and assume that x is normally distributed. 2a. find the sample mean of this data (x ฤโฆ). 2b. find the sample variance of x. find the variance of x ฤโฆ. for (c), (d), and (e), use the appropriate t-distribution 2c. find the 90% confidence interval for the population mean (รฎฤพ). 2d. test the hypothesis that รฎฤพ is equal to 7 at the 95% confidence level. (should you do a one-tailed or two-tailed test here? ) 2e. what is the approximate p-value of this hypothesis?
