A comet following a hyperbolic path about the Sun has a perihelion of 80 Gm. When the line from the comet to the Sun is perpendicular to the focal axis of the​ orbit, the comet is 288 Gm from the Sun. Calculate​ a, b,​ c, and e. What are the coordinates of the center of the Sun if the center of the hyperbolic orbit is​ (0,0) and the Sun lies on the positive​ x-axis?

Ade and abc are similar. which best explains why the slope of the line between points a and d is the same as the slope between points a and b?

50 points~ ! i have to turn this in tomarrow

(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?
