An airplane traveled from Boston to Las Vegas making a stop in St. Louis. The plane traveled 2410 miles altogether, which is 230% of the distance from Boston to St. Louis. Find the distance from Boston to St. Louis to the nearest mile.
Exercise 11.34 from text-book-Chapter 11: Airline passengers get heavier. In response to the increasing weight of airline passengers, the Federal Aviation Administration in 2003 told airlines to assume that passengers average weight 190 pounds in the summer, including clothing and carry-on baggage. But passenger vary, and the FAA did not specify a standard deviation. A reasonable standard deviation is 35 pounds. Weights are not Normally distributed, especially when the population includes both men and women, but they are not very non-Normal. A commuter plane carries 19 passengers. What is the approximate probability that the total weight of the passengers exceeds 4000 pounds? Use the four-step process to guide your work.
A trough is (4) meters long, (2) meters wide, and (1) meters deep. The vertical cross-section of the trough parallel to an end is shaped like an isoceles triangle (with height (1) meters, and base, on top, of length (2) meters). The trough is full of water (density (1000 kg/m**3) ). Find the amount of work in joules required to empty the trough by pumping the water over the top. Because the problem is in metric units, remember to multiply the mass to be lifted by (g=9.8 m/s**2) to convert to a weight.
CALCULUS 1.If you are fencing in an 800 sq ft rectangular garden and one side cost $6 per foot and the other 3 cost $2 per foot, find the dimensions that minimize cost. 2.
The Order of Magnitude for the price of 2 mid-sized cars that average 17,000 dollars is _____.
37. Crossett Trucking Company claims that the mean weight of its delivery trucks when they are fully loaded is 6,000 pounds and the standard deviation is 150 pounds. Assume that the population follows the normal distribution. Forty trucks are randomly selected and weighed. Within what limits will 95 percent of the sample means occur?
An automatic puck shooting machine is a device that fires hockey pucks at specified speeds. The machine’s manufacturer, Puck Chuck, constructed the device so that there was little variance in the velocities of the projectiles. For example, if a machine was to be set at a mean output of 85 miles per hour (mph), its standard deviation would remain 4 mph. Assuming that actual speeds of the device are normally distributed, please answer the following questions about a machine set to shoot pucks at 85 mph: a) What is the probability of a puck being shot at speeds in between 77 and 88 mph? b) If Puck Chuck wanted to reset the machine so that only 17 in 1000 pucks would have velocities of less than 75 mph, what would the mean output of the machine be set to?
Socially conscious investors screen out stocks from alcohol and tobacco companies in favour of more “socially conscious” enterprises. One popular measure of stock value is the P/E ratio (price to earnings ratio), with a high P/E indicating that the stock might be overpriced (pay more for less earnings). The stock index of all major stocks has a mean P/E ratio of 19.4. A random sample of 36 “socially conscious” stocks gave a P/E ratio of 17.9 with a standard deviation of 5.2. Determine, with 95% confidence, if the stocks from “socially conscious” companies are different from the mean P/E ratio of all other major stocks. Please conduct a complete hypothesis test and find the p‐value.
Suppose that 430 ft of fencing are used to enclose a corral in the shape of a rectangle with a semicircle whose diameter is a side of the rectangle as the following figure: Find the dimensions of the corral with maximum area.
Get college assignment help at uniessay writers The volume of a cone varies jointly as the height of the cone and the area of the base. The volume of a cone with height 30 centimeters and base 14 centimeters squared is 140 centimeters cubed. Find the volume of a cone with height 7 centimeters and base 12 centimeters squared.
Suppose that 166 ft of fencing are used to enclose a corral in the shape of a rectangle with a semicircle whose diameter is a side of the rectangle. What is the diameter of the semicircle and the side of the rectangle?
A rectangular pasture of 40,000 square feet is to be fenced in. The pasture will have one side facing the road, and fence for that side costs $20/foot. On the other sides, fencing costs $15/foot. What should the demensions of the pasture be to minimize total fencing cost and what is that optimal cost?
If a tank holds 4500 gallons of water, which drains from the bottom of the tank in 49 minutes, then Torricelli’s Law gives the volume of water remaining in the tank after minutes as V=4500(1-(t/49))^2. Find the rate at which the water is draining from the tank after 5 minutes, 12 minutes, and 20 minutes
Use the numbers 1,2,3,4,5,6,7,8,9 one time each to fill in these circles and make a true equation. One solution is 237 654=891. There are over 300 solutions with 32 different sums. How many can you find?
A swimming pool is circular with a 30-ft diameter. The depth is constant along east-west lines and increases linearly from 5 ft at the south end to 10 ft at the north end. Find the volume of water in the pool. (Round the answer to the nearest whole number.)
Ph.D. Students receive an average of $12837 per year. If the average salaries are normally distributed with a standard deviation of $1500, find these probabilities. a) the student makes more than $15,000. b) the student makes between $13,000 and $14,000.
