  1. Bellringers Second Nine Weeks

  2. October 12, 2010 • Turn the fraction into a percent.

  3. October 18, 2010 • Find 30% of 54. • 12 is 24% of what number? • 40 is what percent of 24?

  4. October 19, 2010 • Use a tree diagram to figure this probability out. • If you flip a coin 4 times, what is the probability of flipping heads, then tails, then heads, and then finally tails? • H • T

  5. October 20, 2010 • Compute the compound probability if you are using a standard deck of 52 cards (no jokers). • What is the probability of drawing a red king, then a face card, and then an even number card without replacing any of the cards? • What is the probability of drawing royal flush one card at a time without replacing any of the cards (hint: can be in any suit)?

  6. October 25, 2010 • Graph each point on a coordinate plane. • (2, -4) • (0, 3) • (-1, -2) • (-3, 0)

  7. October 26, 2010 • Find the range of the function f(x) = x – 6 for the domain: {-2, 0, 5}

  8. October 27, 2010 • Graph the function, by setting up a table, plugging in at least three points for the domain, and then plotting your ordered pairs on the coordinate plane. (Hint: you don’t have to use -1, 0, and 1 as your domain; use multiples of 3 for simplicity.)

  9. October 28, 2010 • Graph the function, by setting up a table, plugging in at least three points for the domain, and then plotting your ordered pairs on the coordinate plane.

  10. October 29, 2010 • Is the equation direct variation? If yes, what is the constant of variation?

  11. November 1, 2010 • Use direct variation to answer the questions. • If Joseph burns 204 calories when he runs 2 miles, how many calories will he burn if he runs 5 miles? • If Eliza can wrap 32 presents in 3 hours, how many can she wrap in 4 ½ hours?

  12. November 2, 2010 • Find a function rule that fits the information provided in the table.

  13. November 4, 2010 Open to page 282. Look in the light blue box and answer questions 1-4.

  14. November 5, 2010 • Find the slope of the line passing through each pair of points. • (a, -b) and (-a, -b) • (-m, n) and (3m, -n) • (2p, q) and (u, 2v)

  15. November 9, 2010 • Put the linear equations in slope-intercept form and then graph the lines. • 3x + 2y = 4 • -2x + y = -1

  16. November 10, 2010 • Put the linear equations in slope-intercept form and then graph the lines. • -5x + 2y = 10 • 3x - 4y = -12

  17. November 12, 2010 • Put the linear equations in slope-intercept form and then graph the lines. • x + 3y = -12 • 3x = 5y + 20

  18. November 15, 2010 • Write the equation of the line that passes through the points (3,4) and (-3, 1) in standard form.

  19. November 16, 2010 • Graph the linear equations.

  20. November 17, 2010 • Determine if the lines are parallel, perpendicular, or neither.

  21. November 18, 2010 • Write the equation of the line with the given conditions in slope-intercept form. • Parallel to the line, and through the point, (-1, 4) • Perpendicular to the line, and through the point, (2, -3)

  22. November 29, 2010 • Graph the line between the points (2, 1) and (-1, 5), and find its slope. • Graph the line between the points (-3, 5) and (-3, 0), and find its slope.
