The drying rate in an industrial process is dependent on many factors and varies according to the following distribution.

minutes relative frequency
13 0.22
14 0.36
15 0.28
16 0.10
17 0.04

if this following sequence represents a simulation of 5 random numbers trials, r (0 less or equal thanrless or equal than1), what is the average drying time: r1 = 0.13 ; r2 = 0.09 ; r3 = 0.19, r4 = 0.21 , and r5 = 0.22.

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
