Suppose the Gulfstream G550 is cruising at an altitude and of 41,000 feet. and 559 miles per hour, respectively. If the plane currently weighs 74,950 pounds, how much thrust is required to maintain these flight conditions? The wingspan is 91.5 feet and the wing platform area is 1,137 square feet. The Oswald efficiency factor is 0.9 and the zero-lift drag coefficient is 0.0165.

Consider the following information regarding the performance of a money manager in a recent month. The table represents the actual return of each sector of the manager’s portfolio in column 1, the fraction of the portfolio allocated to each sector in column 2, the benchmark or neutral sector allocations in column 3, and the returns of sector indices in column 4.

a-1. What was the manager’s return in the month? (Do not round intermediate calculations. Input all amounts as positive values. Round your answer to 2 decimal places.)

a-2. What was her overperformance or underperformance? (Do not round intermediate calculations. Input all amounts as positive values. Round your answer to 2 decimal places.)

b. What was the contribution of security selection to relative performance? (Do not round intermediate calculations. Round your answer to 2 decimal places. Negative amount should be indicated by a minus sign.)

c. What was the contribution of asset allocation to relative performance? (Do not round intermediate calculations. Round your answer to 2 decimal places. Negative amount should be indicated by a minus sign.)

1. Suppose that a fire insurance company wants to relate the amount of fire damage in major residential fires to the distance between the burning house and the nearest fire station. The study is to be conducted in a large suburb of a major city. A sample of 14 recent fires in this suburb is selected. The amount of damage, y, and the distance between the fire and the nearest station, x, are given below. We are interested in building a regression model to predict fire damage y, given the distance from the fire x.

1. Is the predictor distance significant? What is the test statistic and p value?
2. What is the amount of variation explained in the model?
3. What is the standard error of the estimated regression line?
4. Use the final regression equation to predict the damage caused by the fire that is 6.5 miles away from the nearest station.
