Triangle DEF has verticals D(1, 1), E(2, 0), and F(0, 4). It is transformed by a rotation 180 degrees about the orgin followed by a dilation with a scale factor of 3. Find the coordinates of the verticals of the triangle DEF. 1. D(-1, 1) E(0, 2) F(4, 4)
2. D(-1, -1) E(-2, 0) F(0, -4)
3. D(-3, -3) E(-6, 0) F(0, -12)
4. D(-3, 3) E(6, 0) F(12, 0) ​

Aregular hexagon rotates counterclockwise about its center. it turns through angles greater than 0° and less than or equal to 360°. at how many different angles will the hexagon map onto itself?

Powerful women's group has claimed that men and women differ in attitudes about sexual discrimination. a group of 50 men (group 1) and 40 women (group 2) were asked if they thought sexual discrimination is a problem in the united states. of those sampled, 11 of the men and 19 of the women did believe that sexual discrimination is a problem. if the p-value turns out to be 0.035 (which is not the real value in this data set), then at = 0.05, you should fail to reject h0. at = 0.04, you should reject h0. at = 0.03, you should reject h0. none of these would be a correct statement.
