Mrs. Katz is planning her family's trip to the museum. She made a list of expenses. THen she wrote the following expression to show how she can calculate the cost. 6 x (4.20 + 8 + 12 + 3.50) How many people do you think are in the family? how can you tell?

im not sure

step-by-step explanation:

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.
