Easy math equation for y’all, if possible please provide a quick equation that you’d put in a calculator, but it’s okay if not!! Please help <3

yes. we do proportions in probabilities.

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.

it would open into a square depending on the type of envelope i’m not sure about the second part

b. b < 1 might be the correct answer
