Thirty children and forty-five adults were surveyed to determine if children watch, on average, the same amount of television as adults per day. The averages from the study were 3.4 and 2.7 hours per day, respectively. The standard deviations from the study were 2.3 and 1.4 hours per day, respectively. The hypothesis test to use is

this is answer of 144 cubic meters

r and t.

both are 64 degrees.

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.
