In this problem, we are interested in the length of a word in the gettysburg address, which is a quantitative variable. note that the value of the variable varies from word to word. the population of all word lengths has a distribution, a mean and a standard deviation. the parameter of interest here is the mean length of all words. it would be very tedious and time consuming to count every word’s length and determine the mean length. in statistics, we select a sample and hope that the distribution of the sample is similar to

his chances of getting a coin of higher value is 4/19

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.

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
