- ball is thrown from an initial hei llowing. h=2+25t-5t^(2)The KLM Christmas tree Farm owns a plot of land with 5000 evergreen trees.Each year KLM allows retailers of Christmas trees to select and cut trees for sale to individualcustomers. KLM protects small trees (usually less than 4 feet tall) so that they will be availablefor sale in future years. Currently, 1500 trees are classified as protected trees, while theremaining 3500 are available for cutting. However, even though a tree is available for cuttingin a given year, it may not be selected for cutting until future years. Most trees not cut in agiven year live until the next year, but some diseased trees are lost every year. In viewing the KLM Christmas tree operation as a Markov process with yearly periods, we define thefollowing four states:The vice-president of administration wonders whether employees are taking adequate amounts of vacation time. Employee burnout is a concern. Research suggests that an employee taking less than 1.4 weeks of vacation annually is very likely to experience burnout. Analyze the employee vacation data and conduct a hypothesis test with the following results: t = 2.93p = 0.0084 What factors should the vice-president consider in determining the presence of employee burnout? Do employees take more than 1.4 weeks of vacation? What reasons should the vice-president provide to the president to justify the recommendation on employee burnout? Based on the data, is the presence of employee burnout an issue that may negatively impact the company?

A software firm survey of 433 randomly selected adults showed that 43% of them would erase all of their personal information online if they could. Complete parts (a) and (b) below. a. Express the original claim in symbolic form. Let the parameter represent the adults that would erase their personal information. (Туре decimal.

There are 2 robot companies (A and B) that offer the industry. Beverage industry managers want the number of drinks that are filled into bottles not to be spilled. Robots are selected that produce the least spillage. To select the robot to be used, experiments were carried out on both robots and observed the amount of drink that spilled from each bottle.
