Peaches are being sold for $2 per pound. if latex: xx represents the number of pounds of peaches bought and latex: yy represents the total cost of the peaches, which best describes the values of latex: xx and latex: yy? group of answer choicesthe values of both x and y will be real numbers greater than or equal to 0.the values of both x and y can be any real number. the value of x can be any real number, but the value of y will always be a real number greater than or equal to 0.the value of x can be any real number greater than or equal to 0, but the value of y must be an integer greater than or equal to 0.

What number should be added to the expression x^2+3x+ in order to create a perfect square trinomial? 3/2 3 9/4 9

This is about circle theorems. someone asap : (

(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 ě…). 2b. find the sample variance of x. find the variance of x ě…. for (c), (d), and (e), use the appropriate t-distribution 2c. find the 90% confidence interval for the population mean (îľ). 2d. test the hypothesis that îľ 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?
