Lactose intolerance causes difficulty in digesting dairy products that contain lactose (milk sugar). It is particularly common among people of African and Asian ancestry. In the United States (not including other
groups and people who consider themselves to belong to more than one race), 47% of the population is
white, 35% Hispanic, 14% is black, and 4% is Asian. Moreover, 15% of whites, 20% Hispanic, 70% of blacks,
and 90% of Asians are lactose intolerant. Suppose we select a U. S. person at random.

i belive those are the ones that are under 90 degreese.

step-by-step explanation:

the shape,the size and the distance

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.
