1. In a cooking contest, five judges score each contestant. To calculate a contestant’s final score, the judges discard the highest number and lowest number, and then they take the arithmetic average of the remaining numbers. The five judges score a contestant as 6.3, 7.1, 6.4, 6.5, and 6.2. What is the contestant’s final score?
2. ImagesWhich expression is equivalent to the preceding expression?
3. A chemist is making a 50% alcohol solution. How many milliliters of distilled water must the chemist add to 600 milliliters of an 80% alcohol solution to obtain a 50% solution?
4. In a cooking contest, five judges score each contestant. To calculate a contestant’s final score, the judges discard the highest number and lowest number, and then they take the arithmetic average of the remaining numbers.
