You are studying for your final exam of the semester. up to this point, you received 3 exam scores of 96%, 77%, and 74%. to receive a grade b in the class, you must have an average exam score between 80% and 89% for all 4 exams including the final.

find the widest range of scores that you can get on the final exam in order to receive a grade of b for the class. use interval notation.

a. [67, 100]
b. [73, 100]
c. [70, 71]

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

2

step-by-step explanation:

1x2=2
