A computer consulting firm presently has bids out on three projects. Let Ai = {awarded project i}. for i=1, 2, 3, and suppose that P(A1)=.22, P(A2)=.25, P(A3)=.28, P(A1 and A2)=.11, P(A1andA3)=.05, P(A2 and A3)=.07, P(A1 and A2 and A3)=.01. Compute the probability of each event: a) A 1or A2 b) A1c and A2c c) A1 or A2 or A3 d) A1c and A2c and A3c e) A1c and A2c and A3 f) (A1c and A2c) or A3

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α. part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part b suppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part c now try a numerical problem. what is the direction of the vector w = < -1, 6 > ?

At a book fair, joe bought 24 books at 3 for $5 and had $2 left. how much money did he have at first?
