Laying out logistic function equation with Euler's number

Question

Sorry for the incredibly basic question. I've not studied maths but need to understand the how to formulate an equation for something I'm revising.

In the image below I cannot get the same result of 0.0924. I'm sure the result is correct but I cannot reproduce it because I don't know how to formulate the equation using a scientific calculator, ie any brackets, order of operations, etc. I have tried so many permutations but just cannot get the right result.

Please could someone lay out how this should be entered into a calculator as I need to use this formula repeatedly.

Using https://web2.0calc.com/

I have tried e(-2.91+6.26*0.01)/1+e(-2.91+6.26*0.01)

and e-2.91+6.26*0.01/1+e-2.91+6.26*0.01

The same on my scientific calculator.

Answer 1

You typed 0.01 instead of 0.1, left out the power operator ^, and forgot to put brackets around the denominator. The following works:

e^(-2.91+6.26*0.1)/(1+e^(-2.91+6.26*0.1))
