Beanie owns a gas pump that is honest. when the pump reads 26 gallons of gas, you might not get exactly 26 gallons because of random variation, but on average it delivers 26 gallons. the standard deviation is 0.2 gallons. the government is going to do a random check on beanie's gas pump. they will select 81 random times to fill up to where the gas pump says "26 gallons", and then in the lab they will measure it to see exactly how much gas there is. if the amount of gas is off (either too high or too low) by 0.04 gallons on average, they will declare the pump faulty and shut down his gas station. what is the probability they will declare the pump faulty? type in "cannot do" if that is your answer.

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 > ?
