There are 48 cards in a pack and each card is either red or black.
the ratio of the number of red cards to the number of black cards is 1 : 1
8 red cards are removed from the pack.
find the ratio of the number of red cards now in the pack to the number
of black cards now in the pack.
give your answer in its simplest form.

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.
