HELP A Folgers Black Silk K-Cup coffee pod weigh on average .28 oz with a standard deviation of .05 Oz answer to the questions.
1.) what percentage of K-cups can be expected to fall within two standard deviations of the mean?
2.) what is the probability that a K-Cup will have more than three .33 oz?
3.) K-Cups that are more than two standard deviations below the mean are considered to be weak. What percentage of K-Cup are considered to be weak?
4 ) in a standard box of 44 K Cups, how many will weigh between .23 and .38 Oz?
5.? Sam's Club sells K-Cups in a box of 128. How many of them will weigh less than 23 Oz?
6.) the ideal weight for K-Cups are within one standard deviation of the mean, how many of the Sam's Clubs box of K-cups are ideal?

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 > ?
