A trade association reported the annual production of architectural glass by 33 producers in a certain year. The graph shows the production volumes of the 10 largest producers and the combined production of the remaining 23 producers. Production volumes are given in thousands of tons.
Select from each drop-down menu the option that completes the statement most accurately based on the information provided.
For the 10 largest producers of architectural glass, the range of the production volumes was __________ thousand tons.Range = 1st - 10th = 9,600 - 900 = 8,700
Select
8,700.
The ratio of the combined production of the producers ranked 11th through 20th to the combined production of the 23 producers outside the top 10 must be __________.11th through 20th Production : Total Production of Bottom 23 = 11th through 20th Production : 11,500
The production of each of the 11th through the 20th has to be below that of the 10th, which is 900.So, we can determine the following:
Upper Limit of 11th through 20th Production = 10 × Production of 10th = 10 × 900 = 9,000
Max Ratio 11th through 20th Production : Total Production of Bottom 23 = 9,000 : 11,500 ≈ 80 : 100
The production of each of the 11th through the 20th has to be at minimum the average of the bottom 23, which is 11,500/23 = 500. After all, the top 10 have to be at least average.So, we have the following:
Lower Limit of 11th through 20th Production = 10 × Average Production of Bottom 23 = 10 × 500 = 5,000
Min Ratio 11th through 20th Production : Total Production of Bottom 23 = 5,000 : 11,500 ≈ 40 : 100
Select
between 0.40 and 0.80.
Correct answer: 8,700,
between 0.40 and 0.80
