7 The table shows the weights of some chickens. Weight, w kg Frequency
1.5 ≤ w < 2 7
2 ≤ w < 2.5 12
2.5 ≤ w < 3 6
3 ≤ w < 3.5 14

b Find the class that contains the median.

c Find the modal class.

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

C. because 6÷3=2 so 3 is half of six so 3/6
