Chase lives 2 3/5 blocks west of Ellie. They draw a number line to model the situation. Because Ellie lives 3 1/2 blocks east from the school, they give her house the coordinates 3 1/2. Chase incorrectly claims that the coordinate of his house is 6 1/10. a. What is the correct coordinate of Chase's house? b. What is Chase's likely error? A. He subtracted 3 1/2 from the coordinate from Ellie's house. B. He added 3 1/2 to the coordinate for Ellie's house. C. He subtracted 2 3/5 from Ellie's house. D. He added 2 3/5 to the coordinates for Ellie's house. Please help me it would really be the best

Place the following steps in order to complete the square and solve the quadratic equation,

When is g(x) = 0 for the function g(x) = 5.23x + 4?

(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?
