Aunion of restaurant and foodservice workers would like to estimate this year's mean hourly wage, , of foodservice workers in the u. s. last year's mean hourly wage was , and there is reason to believe that this year's value is greater than last year's. the union decides to do a statistical test to see if the value has indeed increased. the union chooses a random sample of this year's wages, computes the mean of the sample to be , and computes the standard deviation of the sample to be . based on this information, answer the questions below. what are the null hypothesis () and the alternative hypothesis () that should be used for the test

i understand 100% 10/10 hit or miss?

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
