There are only green pens and red pens in a box. There are three more red pens than green pens in the box.
Sheila is going to take at random two pens from the box.
17
The probability that Sheila will take two pens of the same colour is
35
Work out the two different numbers of green pens that could be in the box.
Your final line must be written in the form, There could be ... or ... green pens.
In your working, let g stand for the number of green pens.
Write fractions in the form alb. Eg 2g+9 would be written as g/(29 + 9)

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 > ?
