You are traveling on an airplane. the velocity of the plane with respect to the air is 110.0 m/s due east. the velocity of the air with respect to the ground is 40.0 m/s at an angle of 30° west of due north. 1) what is the speed of the plane with respect to the ground? 2) what is the heading of the plane with respect to the ground? (let 0° represent due north, 90° represents due of due north). 3) how far east will the plane travel in 1 hour?

7. see worksheet 1 for values of variables x1, x2 and x3 and answer the following questions: a. for each variable find the mean, median, coefficient of skewness, range and population standard deviation. b. compared to variable x1, how are the mean and median affected by extreme values (outliers) seen in x2 and x3. c. is the median or mean the better measure of location for x2 and x3? explain. d. explain the differences in the magnitudes of the skewness coefficients for the three variables. e. what is the relationship between the range and standard deviation looking across the three variables?
