What is the score range for the smallest percent of students

The score range for the smallest percent of students is:

                         400 to 700

From the pie chart or circle graph that is provided to us the smallest percent of the students are 10%

( Since 10%  is smallest among 14%,42%,34% and 10%)

and we may observe that the smallest region is denoted  or represented by the dark blue region and the range of the score of blue region that is given to us is:

                  400 to 700

   Hence, the answer is:

                   400 to 700

the correct answer is option c.   3

step-by-step explanation:

points to remember

equation of the line with coordinates (x₁, y₁) and (x₂, y₂) is given by,

slope m = (y₂ - y₁)/(x₂ - x₁)

from the figure we can see a line with two coordinates given

to find the slope of given line

here   (x₁, y₁)   = (-1, -1 ) and (x₂, y₂) = (1, 5)

slope m = (y₂ - y₁)/(x₂ - x₁)

  = (5 - -1)/(1 - -1)

  = (5 + 1)/(1 + 1)

  = 6/2 = 3

therefore the correct answer is option c.   3
