Brad is looking out his window daydreaming. The number of people who pass by outside his window per hour is a Poisson random variable (rv) with 0-24. Let Y be the number of people who pass by outside Brad's window during the first hour (a) What is PY-7? (b) Suppose that five people passed by in the first 30 minutes. Given this, what is the probability that Y 17? c) What are E Y and Var(Y)?

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 bsuppose 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 cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
