What is the range of the following set? 28, 45, 12, 34, 36, 45, 19, 20 8 33 45 57

Hello!

To find the range of this set, we must subtract the lowest number in the set from the highest number. 

In this set, the highest number is 45 and the lowest number is 12. Subtract: 

45 - 12 = 33

ANSWER: 

The range of this set is B. 33. 

The range is the highest number subtracted by the lowest. your answer is 45-12=33

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
