En el mes de enero la tasa de desempleo en Estados Unidos descendió a 8.3% (sitio web del Departamento del Trabajo de Estados Unidos, 10 de febrero de 2012). La Oficina del Censo incluyó a nueve estados de la región noreste. Suponga que la variable aleatoria de interés es el número de estados de la región noreste con una tasa de empleo en enero inferior a 8.3%. ¿Qué valores podría asumir esta variable aleatoria?

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 > ?

I'm confused on how to solve the triangle. can someone me ?
