  1. Warm-upDecember 17, 2013 • Copy Agenda message and EQ • Find the mean, median, mode, and range for the following data set: • 16, 25, 52, 42, 37, 26, 80, 42 • Is there an outlier? If so, what is it?

  2. Semester Test Review • Wilma puts $1,200 in a savings account that earns 5% interest per year. How much will she have after 2 years? • A recipe for rolls requires ½ cup of flour to make 8 rolls. What is the simplified unit rate of flour to rolls? • Marco wants to buy a new skateboard whose original price is $36, but is on sale for 25% off. If Marco only has $26.50, does he have enough to buy the skateboard? • Side Length 1 2 3 4 5 Perimeter5 10 15 20 25 What is the equation for this table?

  3. Semester test review • Minutes studied 5 10 15 Test Score 25 50 75 Is this relationship proportional? If so, what is the constant of proportionality (unit rate)? • On a map with a scale of 1 inch = 8 miles, two towns are 4 inches apart. How many miles apart are they? • Your bill at Joe’s Crab Shack was $58. You decide to leave a 20% tip. What fraction can you use to determine the tip amount? What is the tip?

  4. Kirsten made 4/5 of her free throws for the season. What percent did she miss? If she made 40 free throws, how many did she attempt? • What is the unit rate if it costs $6.00 for 8 grapefruit? • Expand the expression: 3 ( 12G – 6Y) – 7P • The sum of three consecutive numbers is 18. What are the 3 numbers? • 4b + 10 = 70 Solve for b • Neka has $20 to spend. After buying 25 pencils she has $16.25 left. How much did each pencil cost?

  5. Mean Absolute Deviation(MAD) • Find the mean. • Calculate the deviation of each number in the data set to the mean. (ie find the difference) • Make all the deviations positive (their absolute value) • Find the mean of all the deviations. • The MAD will ALWAYS be a positive value.

  6. Warm-upDecember 17, 2013 • 16, 25, 52, 42, 37, 26, 80, 42

  7. Warm-upDecember 16, 2013 • Calculate the MAD: • 25, 27, 35, 17, 42, 18, 20, 28, 67, 27, 24 • This is your TOTD!
