You’re locked out of your house and the only open window is on the second floor, 33 feet above the ground. You need to borrow a ladder from one of your neighbors. There’s a bush along the edge of the house, so you’ll have to place the ladder 15 feet from the house. What length of ladder do you need to reach the window? [a] Round your answer to three decimal places.

Read and answer the following question. If a calculation is not possible, type NA. The population of weights for men attending a local health club is normally distributed with a mean of 182 lbs and a standard deviation of 30 lbs. An elevator in the health club is limited to 34 occupants, but it will be overloaded if the total weight is in excess of 6698 lbs.Assume that there are 34 men in the elevator. What is the average weight per man that, beyond which, the elevator would be considered overloaded? average weight = [a] lbs What is the probability that one randomly selected male health club member will exceed this weight? P(one man exceeds) = [b] round to 2 decimal places If we assume that 34 male occupants in the elevator are the result of a random selection, find the probability that the elevator will be overloaded? P(elevator overloaded) = [c] round to 4 decimal places

It has been reported that 7 % of phones manufactured by a certain company for a product launch did not meet the quality standards. An engineer needs at least one defective Phone so she can try to identify the problem(s). If she randomly selects 15 phones from a very large batch, what is the probability that she will get at least 1 that is defective? Is that probability high enough so that she can be reasonably sure of getting a defect for her work? Probability that at least one phone out of a sample of 15 is defective is (round to 4 decimal places). [a] Is the probability high enough so that she can be reasonably sure of getting a defect for her work? Type Yes or No in the box below.  [b]
