Does anyone know the common difference of -7,-9,-11?

I’m pretty sure that it’s 2 because your suppose to subtract the term from the term that follows it.

d= -2

Step-by-step explanation:

-7-2= -9

-9-2= -11

-11+2 = -9

-9+2= -7

his chances of getting a coin of higher value is 4/19

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.
