Of all the students in a particular class, 20% have blue eyes. we want to run a simulation to predict how many blue eye students will be chosen if we randomly select 10 students. first, we need to assign digits to students that have blue eyes and students that do not have blue eyes. if we were to use single digits to represent both, which of the following would be a correct method of assigning these digits?

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.
