Amusic teacher grades on an e (excellent), s (satisfactory), and u (unsatisfactory) grading scale. a final score of more than 92 earns an e. a final score of 60 or less earns a u. any other score earns an s.
zeb says that the inequality x> 60 represents a grade of s. is zeb correct? explain using a complete sentence.

mostly correct

Step-by-step explanation:

instead of x>60 it should be greater than or equal to since reciving a 60 would result in a S.

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.

the answer is  

a.
