2. A heavy vehicle has five identical axles each of which has 8 identical wheels, fouron each side. Each axle can function if it has at least 3 fully inflated tires on eachside. The reliability of each of the tires in use is 90%.a) If three out of five axles must be operational for the vehicle to function, whatis the reliability of the vehicle?• R= 0.9910R = 0.8642R = 0.9477R = 0.8981

Each tire has a reliability of 0.9 but for an axle to be fully functional it is required to have at…

Joan's Nursery specializes in custom-designed landscaping for residential areas. The estimated labor cost associated with a particular landscaping proposal is based on the number of plantings of trees, shrubs, and so on to be used for the project. For cost estimating purposes, managers use two hours of labor time for the planting of a medium- sized tree. Actual times from a sample of 10 plantings during the past month follow (times in hours). Select your answer - 2 t Họ:1 H₂H b. Compute the sample mean. (to 2 decimals) c. Compute the sample standard deviation. (to 4 decimals) d. Find the test statistic and p-value.

An instructor has graded 20 exam papers submitted by students in a class of 21 students, and the average so far is 68. (The maximum possible score is 100.) How high would the score on the last paper have to be to raise the class average by 1 point?

A certain faculty printer is shared by staff and students. Suppose that the rate of generating requests to the printer by staff is twice that of students, but that the average time to print a student printout is the same as average time for a faculty printout. If the utilization of the printer by the students is 25%, the utilization of the printer by the faculty is 50%, the overall average service time is 1 minute, what is the average time the students spend waiting for their printout (time spend in system)?
Assume there are 3500 undergraduate students studying at AUA, 1800 students have taken Business Math (denote with BM), 1500 students have taken Environmental Science (denote with ES), and 1400 AUA students have taken both Environmental Science and Business Math. Select one answer. Select one: a. P(ES or BM)= 0.543, P(ES' and BM)= 0.11 b. P(ES or BM)= 0.942, P(ES' and BM)= 0.51 c. P(ES or BM)= 0.543, P(ES' and BM)= 0.51 d. P(ES or BM)= 0.943, P(ES' and BM)= 0.11
During one the nurse’s hourly assessments, Ana is lethargic, her respirations are 8/minute and her DTRs are absent. The nurse identifies this as magnesium sulfate toxicity and after informing the obstetrician the following is ordered: stat magnesium level, stop the magnesium infusion, calcium gluconate, 1 gm IVP over 3 mins. One hour later her magnesium level is 7 mg , therapeutic for preeclampsia (4.7 to 8 mg/dl). The nurse evaluates the intervention. The patient has normal CNS functioning; is alert and oriented; respiratory rate is 16; DTR 2+, and urine output 75 mL so the magnesium sulfate is restarted at 1 g/hr per provider order. With the same solution of 40 g/liter, at what rate (mL/hr) would the nurse set the infusion pump?
A typical treatment for Acinetobacter baumannii infection, for example, is a regimen of ampicillin, consisting of 250 mg, 4 times a day for 1 week. But antibiotics are used for a variety of medical issues by many people in the United States. Based on this information, estimate the weight, in kilograms, of ALL antibiotics ingested by people in the US each year. State any other assumptions and show all of your work.
