  3. Data for 100 Find the mode of the data: 21, 15, 2, 21, 28, 7, 1. 21 Mode: the value or values that occur most often in a data set. A data set may have more than one mode or no mode.

  4. Data for200 Find the range of the data. 9, 25, 23, 4, 5, 28, 17, 8, 29, 10, 10, 5 25 The range of data is the difference in the maximum and minimum data.

  5. Data for 300 Find the median of the data: 21, 15, 2, 22, 8, 8, 7, 1. 8 To use your calculator, select STAT, Edit and place the numbers in a list. To perform calculations like median and mean goto 2nd LIST, MATH, select the operation and the List.

  6. Data for 400 Find the mean of the data: 21, 15, 2, 22, 8, 8, 7, 1. 10.5 Mean: the number obtained by dividing the sum of the values in a data set by the number of values. Often called the average.

  7. Data for 500 Find the five-number summary for the data. 4,6,8,8,11,14,16,20,21,22,25 4, 8, 14, 21, 25 To use your calculator to create a box plot: Enter your data into a list, go to STATPlot, select a box plot and your data list, graph.

  8. Equations for 100 Given the equation, y = 5x + 3 and that x = 2, what does y equal? y = 13

  9. Equations for 200 Find an equation of the line with slope 2 and y -intercept 7. y = 2x + 7

  10. Equations for 300 Find the slope of a line that passes through points at (3,1) and (5, 5).

  11. Equations for 400 Write an equation that satisfies the data in the table. +2 +6 6 y = 9 + 3x Slope = ______ = 3 2

  12. Equations for 500 Find the point-slope form of the equation of the line with slope 3 passing through the point (-1, 7). y = 7 + 3 (x - -1) or y = 7 + 3 (x + 1) in which is a point on the line and b is the slope.

  13. Solving Equations for 100 Solve. 15 = y -12 y = 27

  14. Solving Equations for 200 Solve. 8x -4 = 28 x = 4 Check your answer by placing it back in the equation.

  15. Solving Equations for 300 Solve. 7x + 5 = x + 35 x = 5 Use the method we learned in class or for multiple choice try the answers in the question.

  16. Solving Equations for 400 Solve. 9m + 3 = 3(m - 5) m = -3 To distribute multiple 3 by m and by -5.

  17. Solving Equations for 500 Solve. 6 < 21 - 5y 3 > y or y < 3 When multiplying or dividing by a negative number reverse the inequality sign. Check a number that is less than 3. For example is 6 < 21 – 5*0

  18. Graphing for 100 What are the coordinates of the point and which quadrant is it located? (-1, 1) is located in Quadrant II

  19. Graphing for 200 Find the slope.

  20. Graphing for 300 Write the equation of this line:

  21. Graphing for 400 Graph the equation: y = 6 + 2x Line that crosses the y-axis at 6 and has a slope of 2.

  22. Graphing for 500 Graph a line that passes through the point (-2, 5) and has a slope of . Check your answer creating an equation in point-slope form and then distribute and place in y – intercept form.

  23. Exponents for 100 Write in exponent form.

  24. Exponents for 200 Evaluate and answer in fraction form. To convert a decimal to a fraction use MATH ►Frac enter on your calculator.

  25. Exponents for 300 Simplify. Power of Product: Any product raised to a power, raise each factor to that power.

  26. Exponents for 400 Simplify Zero Power: Any base raised to the zero power is one. (Except the base of zero.)

  27. Exponents for 500 Simplify Negative Power: any base raised to a negative exponent, reciprocal the base to the positive exponent.

  28. Potpourri for 100 Solve the proportion: x = 14 Multiply both sides by 4 to solve for x.

  29. Potpourri for 200 Find the next term in the pattern: 1, - 4, 16, -64, ... 256 The initial value is 1 and the recursive rule is multiple by -4.

  30. Potpourri for 300 The first row in a theater has 16 seats, the second row has 22 seats, and the third row has 28 seats. If this pattern continues, how many seats will the sixth row have? 46 seats are in the sixth row.

  31. Potpourri for 400 A swimmer went 200 yards in 2 minutes. What is the rate in feet per second (ft/sec)? 5 ft/sec

  32. Potpourri for 500 Game wardens use experiments to help determine the number of fish in a lake. Suppose 120 fish are caught, tagged, and released back into the lake. Two weeks later 40 fish are caught, 4 of which are found to have tags. Using this information, estimate the number of fish in the lake. ~1200 fish are in the lake. Set up a proportion comparing tagged to total fish.
