The Carbondale Hospital is considering the purchase of a new ambulance. The decision will rest partly on the anticipated mileage to be driven next year. The miles driven during the past 5 years are as follows:
| Year | 1 | 2 | 3 | 4 | 5 |
|---|---|---|---|---|---|
| Mileage | 3,050 | 3,950 | 3,500 | 3,850 | 3,700 |
a) Using a 2-year moving average, the forecast for year 6= _______ miles (round your response to the nearest whole number).

QUESTION 5
The Layton Tire and Rubber Company wishes to set a minimum mileage guarantee on its new MX100 tire. Tests reveal the mean mileage is 67900 with a standard deviation of 2050 miles and that the distribution of miles follows the normal distribution. They want to set the minimum guarantee mileage so that no more than 4 percent of tires will be replaced. What minimum guaranteed mileage should Layton announce?

A student bikes to school by traveling first dN = 1.10 miles north, then dW = 0.500 miles west, and finally dS = 0.200 miles south.
Part A
If a bird were to start out from the origin (where the student starts) and fly directly (in a straight line) to the school, what distance db would the bird cover?
Part B
Let the vector dN be the displacement vector corresponding to the 1st leg of the trip. Express dN in component form.
Part C
For the 2nd leg (dW):
Part D
For the 3rd leg (dS):
Part E
The displacement vector for the bird, db can be written as dN + dW + dS. Express this vector in component form:
Part F
Find φ, the angle North of West of the path followed by the bird.
