An airplane flies 450 km from Raleigh to Washington DC at 500 km hr. It stops...
•An airplane flies East (+x) for 2 hours at 500 mile/hr •Then North (+y) for 1 hour at 450 mile/hr •Then West (-x) for 1 hour at 400 mile/hr •What is the average velocity for that 4 hour period? x & y components and magnitude and direction
The pilot of an airplane with a speed of 280 km/hr relative to the air, wishes to fly due east from the city A to city B. If a 35 km/hr wind blows from the south to the north, and the distance between the cities is 1, 500 km, A) what is the velocity ( magnitude and direction) of the plane relative to the ground, B) how long will the trip take?
1. Calculate the mean and standard deviation for each variable
using formulas or functions. 2. Calculate descriptive statistics
for each variable using the Analysis Toolpak. 3. Calculate the
coefficient of variation for each variable. What general
interpretation can you make from these values? 4. Calculate the
correlation between Revenue and Employees using a formula.
Calculate the coefficient of determination. 5. Create a correlation
matrix for the eight numerical variables. Note any relationship of
