If a football player positioned on the scrimmage line runs straight downfield for 26 yards and then cuts to his left for 6.0
yards to receive a pass, what is the football player's total displacement from the scrimmage line? (Use trigonometry to
answer, but remember to draw a diagram to help your understanding.) Give both the magnitude and the angle in your
answer.
A) 33 yd and 14° to the left of the scrimmage line
B) 33 yd and 13 to the left of the scrimmage line
C) 27 yd and 13° to the left of the scrimmage line
D) 27 yd and 14 to the left of the scrimmage line

An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27°c, and 750 kj/kg of heat is transferred to air during the constant-volume heat-addition process. assuming constant specific heats at room temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (4390 kpa, 1730 k; 423 kj/kg; 56.4%; 534 kpa)

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?
