There are 30 drummers competing in the Battle of the Bands this year. Next year, 5 of the drummers will leave and some new drumm
ers will join the competition. If d is the number of drummers who will join the competition, which expression(s) represent the number of drummers in the competition next year.
Since there are 30 drummers competing in the Battle of the Bands this year and, 5 of the drummers will leave the following year, the number of drummers left will be gotten by the expression:
= 30 - 5
If If d is the number of drummers who will then join the competition, therefore, the expression that represent the number of drummers in the competition next year will be gotten as:
Because the numbers are lined up from least to greatest all you have to do is find the middle of all the numbers which is 10. So everything below ten is lower quartile. Everything above is upper quartile
