Suppose that you are taking a course where the total class grade is the weighted average of your homework, worksheets, quizzes and tests. The homework is worth 15% of the course grade, worksheets are worth 20% of the course grade, the quizzes are worth 25% of the course grade, and tests are worth 40% of the course grade. To get a B in the course, you must have an overall average of at least 80%.

Your current grades in each category are:

Homework =
80
%, Worksheets =
78
%, and Quizzes =
53
%.

What is the minimum test average you need to get a B in the course?.

Your answer is:
% (Round to at least 1 decimal place)

pleaze mark brainliest!

8 2/3 is the answer

step-by-step explanation: just use a calculator

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
