What is the average temperature of the tropopause?
every time i add it in google it comes up with things for the troposphere or is it the same thing? please answer today? ~~thank you!~

As said above, the tropopause is the border between the troposphere and stratosphere. It is the place where the adiabatic lapse rate (how fast the temperature sinks with altitude) stops sinking and, eventually, becomes positive. That is an inversion and there is nothing to bring clouds above.
The temperature at the tropopause varies from perhaps -50 C at the poles, to sometimes as cold as -80 at the equator. This is an interesting fact because it means that the difference of temperature between the surface and the tropopause is nearly the double at the equator than the poles. Warmer air being less dense, it also means that if the tropopause is perhaps 10 km high at the poles, it can be as high as 17 km at the equator.
Now, if we understand that the the thermal "chimney" at the equator is much longer and with a much greater difference of temperature, we also understand why we get powerful equatorial thunderstorms but not at the poles! It makes sense, doesn't it?

The tropopause is the border between the troposphere and the stratosphere. The temperature at the tropopause is usually minus 40 degrees F (minus 40 degrees C).

The tropopause is the atmospheric boundary between the troposphere and the stratosphere.
Its temperature is -60° C to -50° C .
