Question Solved1 Answer I need explanation please! 35. FILE Retailer. An online retail company is trying to predict customer spending in the first three months of the year. Brian Duffy, tł marketing analyst of the company, has compiled a data set on 200 existing customers that includes sex (Sex: Female/Male), annual income in 1,000s (Income), age (Age, in years), and total spending in the first three months of the year (Spending). A portion of the data is shown in the accompanying table. Sex Income Age Spending Male 87.50 52 156.88 Female 66.50 43 275.16 : : : : Male 51.90 61 159.51 a. Which of the above variables are categorical and which are numerical? b. What is the measurement scale of each of the above variable?

The lives of parts are often expressed as the number of cycles of operation that a specified percentage of a population will exceed before experiencing failure. The symbol L is used to designate this definition of life. Thus, we can speak of L10 life as the number of cycles to failure exceeded by 90% of a population of parts. Given a normal distribution The lives of parts are often expressed as the number of cycles of operation that a specified percentage of a population will exceed before experiencing failure. The symbol L is used to designate this definition of life. Thus, we can speak of L10 life as the number of cycles to failure exceeded by 90% of a population of parts. Given a normal distribution model, with a mean of I = 124.9 kilocycles and standard deviation of så = 33.3 kilocycles, estimate the corresponding 410 life. The corresponding L10 life of the part is 84.1 kilocycles.

Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. To place a communications satellite into a geosynchronous orbit at an altitude of 22,240 mi above the surface of the earth, the satellite is first released from a space shuttle, which is in a circular orbit at an altitude of 185 mi, and is then propelled by an upper-stage booster to its final altitude. As the satellite passes through A, the booster's motor is fired to insert the satellite into an elliptic transfer orbit. The booster is again fired at Bto insert the satellite into a geosynchronous orbit. The second firing increases the speed of the satellite by 4850 ft/s. 29.240 mi 185 mi R-3960 mi Determine the speed of the satellite as it approaches B on the elliptic transfer orbit. (You must provide an answer before moving to the next part.) The speed of the satellite as it approaches Bis ft/s.

6. (20 pts) Eurostar is a high speed rail service that connects London to Paris. The distance from London to the English Channel Tunnel is 108.0 km. The English Channel Tunnel is 50.5 km long. The distance from the English Channel Tunnel to Paris is 316.0 km. The train travels at a maximum speed of 300 km/hr except within the English Channel Tunnel, where a 6.

The distance from the English Channel Tunnel to Paris is 316.0 km. The train travels at a maximum speed of 300 km/hr except within the English Channel Tunnel, where a reduced speed of 160 km/hr is required for safety reasons. a. How long does the journey from London to Paris take? Give you answer in s. b. If the resistance between the train and the track at maximum speed is 120 kN and air resistance adds an additional 20.5 kN (Note: Power = force x velocity), what is the power in horsepower required to power the engine?

PLEASE IN C++ 1) Chuck-a-luck - 15 pts Chuck-a-luck is a simple dice game for gamblers. You can play it in some Vegas casinos. To play, the gambler first places a wager, W. The gambler then picks any number from 16. Let n represent the gambler's number. Next, the gamber rolls three six-sided dice. If none of the rolls equals n then the gambler loses W. If
