Mr. Nelson is checking some of the school's sports balls to make sure they are in good shape and properly inflated. Use the table to recommend air pressures to define the ranges for properly inflated balls. Ball Average Recommended psi Tolerance (pounds per square inch) Soccer Ball 12.05 +/- 3.55 Basketball 8.00 +/- 0.5 Volleyball 4.44 +/-0.18 Part 1: What is the absolute value inequality for the recommended air pressure range for each type of ball. Use the variable x for the ball's actual air pressure. (Please make sure it is an absolute value inequality, meaning it has the absolute value function in the inequality.) Soccer Ball: Basketball: Volleyball: Part 2: Choose one type of ball and write its absolute value inequality describing the air pressure of balls outside the recommended range. Part 3: What is the appropriate range for air pressure for the type of ball you selected in Part 2? (based on the information given in the last two problems)
