Suppose the school wants an overall average of 90%. The following data represent the averages of 8 other classrooms. What grade would the 9th classroom need in order for the average among all classes to be at least a 90%? Class 1 Class 2 Class 3 Class 4 Class 5 Class 6 Class 7 YOUR CLASS Class 9 93 80 70 86 68 92 74 ?? X The formula for solving this question is below. Replace the words, "Your Class Average," with the answer you found in question 5 and solve for X. Show each step of your work. 93 + 80 + 70 + 86 + 68 + 92 + 74 + Your Class Average + x ! = 90 9 First, add all the numbers in the numerator together: Focusa to this PC Search (Alt+Q) victor santiago Draw Design Layout References Mailings Review View Help careful-files from the Internet can contain viruses.
