A fair five-sided spinner is spun. Write, as fraction, the probability of the spinner

landing on:

1

An odd number

2 or 5

Jill says “If I spin the spinner 5 times I will definitely get a 3 once.” Do you think she is right? Why?

false

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.
