Maggie studied for 2/5 of an hour. Julie studied for 1/4 of an hour how much longer did Maggie study

Maggie studied for 3/20 of an hour more.

Step-by-step explanation:

2/5 - 1/4 = x

8/20 - 5/20 = 3/20

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.
