Q. The following data points represent the number of points scored last basketball game by each player on the Dragons basketball team.\newline5,8,11,7,?5,8,11,7,?\newlineIf the mean of the data set is 88 points, find the missing number of points.\newline\square points
  1. Add Points: First, let's add up the points we know: 5+8+11+75 + 8 + 11 + 7.\newlineThat's 3131 points so far.
  2. Calculate Total Points: Since there are 55 data points including the missing one, and the mean is 88, we multiply 55 by 88 to find the total points.\newline5×8=405 \times 8 = 40 points is the total we need for an average of 88.
  3. Subtract and Find Missing: Now, subtract the sum of the known points from the total points needed.\newline4031=940 - 31 = 9 points.\newlineSo, the missing number is 99 points.
