Last week’s and this week’s daily high temperatures are shown in the table below. high temperatures for this week and last week high temperatures this week (mc001-1.jpg) 65 73 73 74 73 75 71 high temperatures last week (mc001-2.jpg) 68 51 62 66 85 72 72 how much greater is this week’s median temperature than last week’s median temperature? 2 degrees 3 degrees 4 degrees 5 degrees

You must take the average of the last week and of the current week dividing the sum of the temperatures given between the amount of temperatures given.
 For the current week:
 (65 + 73 + 73 + 74 + 73 + 75 + 71) / 7 = 72
 For last week
 (68 + 51 + 62 + 66 + 85 + 72 + 72) / 7 = 68
 this week's medium temperature 4 degrees greater than last week's medium temperature

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
