1. In a bag full of marbles, there were 6 green, 2 red and 4 blue marbles. If a marble is chosen from the bag and then returned, find
a) P(green)
b) P(red)
c) P(blue)
d) P(not blue)
2. The ratio of girls to boys in Mr. D’s class is 12 : 13. What is the ratio of girls to all students in Mr. D’s class?
3. Solve for y in the similar figures.

x-axis: ◦ The horizontal # line
y-axis: ◦ The vertical # line
Origin: ◦ where the two # lines cross each other
Quadrants: ◦ The 4 quarters: ◦ I, II, III, & IV
Ordered Pair:◦ Pair = 2◦ Order is x 1st then y … (x,y)

Use the table of values listed to the right
a. Write the ordered pairs from the table using parentheses.
(-3, -6), (-2, -4), (-1, -2), (0, 0), (1, 2), (2, 4), (3, 6)
b. Graph the ordered pairs on a coordinate plane.

a. Make a scatter plot of the data. Label the x-axis “age” and the y-axis “height.”
b. Is there are relationship between the age of a person and the person’s height?
Yes, as the age increases so does the height.
c. Do you think this relationship will continue until someone is 70 years old? Explain.
No. People stop growing.
