A student rolls a number cube, numbered 1-6, and spins the spinner. Make a table of the possible outcomes.
Red Blue
Yellow Green
Generalize Explain when you would choose a graph or a table to show a frequency distribution.
Multiple Choice Which expression represents the probability of getting a 4 or 5 on
three number cubes, numbered 1-6, and heads on four coins?
A P=_4 ·_5 ·_4 B P=_1 ·_1 ·_1 662 662
_1 2 _1 4 _1 3 _1 4 C P=(6)·(2) D P=(3)·(2)
Chemistry Experiments in a chemistry lab either succeed or fail. They also can be characterized as chemical or physical reactions. Make a table to show all the possible outcomes.
Probability A bag contains 3 red marbles and 7 blue marbles. A marble is drawn and replaced. Use an equation to show the probability of drawing 3 red marbles in a row.
Physics An object is thrown from a tower. The expression -16x2 + 32x + 48 represents its height after x minutes. Factor this expression completely.
Error Analysis Two students factor 2x2 - 2x - 12. Which student is correct? Explain the error.
Geometry A square has area 9m4 - 54m3 + 81m2 square inches. What is its side length? Multi-Step The volume of a rectangular cereal box is represented by the expression
3x3 + 3x2 - 18x.
a. Factor the expression completely.
b. What are the dimensions of the box?
Error Analysis Students were asked to find the excluded values for _5m . Which m+3
student is correct? Explain the error.
Student A
(2x + 4)(x - 3)
Student B
2(x + 2)(x - 3)
Student A
m+3≠0 m≠3 m≠3
Student B
m+3≠0 m ≠ -3 m ≠ -3
