One Hundred students were asked how they travelled to school. Of the girls, 19 rode in a car, 7 rode the bus, and 27 took the train. Of the boys, 12 took the train, 25 rode in a car and 10 rode the bus. Construct a two-way frequency table. Then tell which mode of transportation is the most popular. Explain.

200 people responded to a survey. Of those who had green eyes, 7 had blonde hair, 9 had brown hair and 2 had red hair. Of those who had brown eyes, 76 had blonde hair 89 had brown hair, and 17 had red hair. Construct a two-way table to display these data. Then identify the least common combination of eye and hair color. Explain.

A Washerman asks 75 people from two different cities if they own rain boots. Complete thetwo-way frequency table to show the results of the survey.

What pattern do you see in the two-way frequency table?

Jesen asked 100 people at his school whether they prefer digital or print textbooks. Construct a two-way frequency table that shows the relationship between the persons position and their textbook preference.

Yumiko solved . Explain the error Yumiko made ?

Absolute value of a variable has many uses in mathematics. Geometrically, the absolute value of a number may be considered as its distance from zero regardless of its direction. The symbol |.| is pronounced as ‘modulus’. We read |x| as ‘modulus of x’ or ‘mod x’.

How is solving an absolute value equation similar to solving an equation that does not involve absolute value? How is it different?
