Answer:
divide 12,000 by the radius of the cylinders face
Step-by-step explanation:
Part A: The school with the lowest value of σ is High School B. This also is the school with the lowest IQR.
Part B: The highest mean is that of High School C, which has average attendance 11 more than the next lower school (A).
2000 * .1 = 200 + 2000 = 2200 (First year)
2200 *.1 = 220 + 2200 = 2420 (second year )
2420* .1 = 242 + 2420 = 2662 (third year )
2662 * .1 = 266.2 + 2662 = 2928.2 (fourth year)
They spent $2928.2 on clothing for 4 years.
