A math student programmed a calculator to randomly generate a number from 11 to 20. The results of the first 50 numbers generated are shown in the table belon, > Random Number Generator Number Frequency 3 12 3 13 5 6 15 0 16 7 18 4 19 8 20 6 Which number was generated the exact number of times the theoretical probability would indicate it should appear? O A 11 O B. 14 O C 13 O D. 18

Suppose you want to transform the graph of the function y=tan(x+pi/4)-1 into the graph of the function y=-tan(x+pi/2)+1 which transformations should you perform. a) reflect the graph of the first function across the x-axis, translate it pi/4 units to the left, and translate it 2 units up. b) reflect the graph of the first function across the x-axis, translate it pi/4 units to the right, and translate it 2 units up. c) reflect the graph of the first function across the line y = -1, translate it pi/4 units to the left, and translate it 2 units up. d) reflect the graph of the first function across the line y = -1, translate it pi/4 units to the right, and translate it 2 units up.
