One barge from Inland Waterways, Inc. can carry a load of 5546.8 lb. Records of past trips show that the weights of the cans that it carries have a mean of 109 lb and a standard deviation of 14 lb. For samples of size 49, find the mean and standard deviation of x.
A) μx = 109; σx = 2
B) μx = 2; σx = 109
C) μx = 14; σx = 109
D) μx = 109; σx = 14

The line y = x + passes through (−3, 7) and is parallel to y = 4x − 1.

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.

The statement tan theta= -12/5, csc theta=-13/12, and the terminal point determained by theta is in quadrant two
