If 1 3 of a mile of state highway litter is removed equally by 4 volunteers, what fraction of a mile will each volunteer clean?

answer:

2. using the information in the histogram, the total number of students surveyed is 4 + 4 + 6 + 4 + 2 = 20.; 3. referring to the box plot, the median of the data is 50. ; 5. the range of the data can be found using the box plot.

step-by-step explanation:

adding together the frequencies of the bars in the histogram gives us the total number of students.

the firs bar goes to 4; the second bar goes to 4; the third bar goes to 6; the fourth bar goes to 4; and the last bar goes to 2.   this gives us 4+4+6+4+2 = 20.

we cannot find the number of students using the box plot.

in the box plot, the line in the middle of the box is the median; this is 50.

estimating the median using the histogram gives us a value of around 48.

the range of the data can be found by subtracting the highest and lowest values found in the boxplot; 70-25 = 45.

we cannot use the histogram to find the range.
