The area of a rectangular room is 750 square feet. The width of the room is 5 feet less than the length of the room.
Which equations can be used to solve for y, the length of the room? Select three options.
y(y + 5) = 750
y2 โ 5y = 750
750 โ y(y โ 5) = 0
y(y โ 5) + 750 = 0
(y + 25)(y โ 30) = 0

(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?
