  1. MMMR – Missing Measure

  2. What do you think his missing grade is? Estimate a value. Brandon has a 95 average in math class. There were 5 assignments, but he can only find 4 of the papers that were passed back. What did he make on the missing assignment if his 4 grades are 89, 92, 96, 98?

  3. Steps for finding the Missing Measure 1. Identify the Average and the NumberofItems. 2. Create the CircleDiagram. 3. Multiply the Average and the NumberofItems to find the TotalPoints. 4. Fill in the CircleDiagram. 5. Add the values you know together and subtract the number from the totalpoints.

  4. The Circle Diagram Total Points Number of Items Average

  5. Brandon has a 95 average in math class. There were 5 assignments, but he can only find 4 of the papers that were passed back. What did he make on the missing assignment if his 4 grades are 89, 92, 96, 98? Total of Known Values: Total Points 89 + 92 + 96 + 98 = 375 95 X 5 = 475 Missing Value: 95 5 475 - 375 = 100 Average Number of Items

  6. Jacob needs to make a 93 in math class, so he can get a raise in his allowance. Currently his grades are 85, 83, 90, and 87. What does Jacob need to make on his next assignment to make a 93 in math class? Total of known values: Total Points 85 + 83 + 90 + 87 = 345 465 93 X 5 = Missing Value: 93 5 465 - 345 = 120 Average Number of Items

  7. The mean of a data set of 3 numbers is 15. The mean of a data set is of 6 numbers is 30. What is the mean of the combined data sets? Total points for data set 1: Mean: 15 x 3 = 45 225 ÷ 9 = 25 Total points for data set 2: 180 30 X 6 = Total points for both data sets: 45 + 180 = 225
