HELP QUICK!!! A large bakery makes thousands of cupcakes daily in two shifts: shift A and shift B. Suppose that, on average, cupcakes from shift A weigh 130g with a standard deviation of 4 g. For shift B, the mean and standard deviation are 125g and 3g respectively. Assume independence between the shifts.

Every day the bakery takes a simple random sample of 40 cupcakes from each shift. They calculate the mean weight for each sample, then look at the difference between the sample mean (A – B).

Find the probability that the mean weigths from the samples are more than 6 grams apart from each other.

show all work by:

1. Defining the parameter(s)

2. Stating the assumptions

3. Stating the parameters

4. Finding a probability

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 > ?
