The following are the ages (years) of 5 people in a room: 18, 21, 12, 12, 23
A person enters the room.
The mean age of the 6 people is now 22.
What is the age of the person who entered the room?

95.03 is the answer. hope this !

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.

answer: the answer is d
