A bag of marbles contains 3 red marbles, 5 green marbles, and 7 blue marbles. If joseph reaches in pulls out one marble, what is the probability that the marble will not be red?

the answer is 12/15, or 4/5. That's also 80%.

Step-by-step explanation:

do you have the measurements?

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.
