Write the real form of each complex equation.
a. z = 4 cos(theta) + 9i sin(theta)
b. z = 6 cos(theta) + i sin(theta)
c. z = √5 cos(theta) + √10i sin(theta)
d. z = 5 − 2i + 4 cos(theta) + 7i sin(theta)

50 people men and women were asked if they watched at least one sport on tv. 20 of the people surveyed are women, but only 9 of them watch at least one sport on tv. 16 of the men watch at least one sport on tv. make a a two-way table and a relative frequency table to represent the data.
