I got 5/9 as my answer which isn't right...

4. CliffSedge

Yeah, 5/9 is way too big. Do you only need x-bar and not y-bar?

5. Dido525

Only x bar.

6. Dido525

So apparently the correct answer is 0.278 but I dont see how...

7. CliffSedge

Is this what you started with? $\huge x-bar=\frac{\int x^{5/4} dx}{\int x^{1/4} dx}$

8. Dido525

Yep.

9. Dido525

The limits of integration are from 0 to 1 I believe.

10. CliffSedge

Hmm, seems to be something missing..

11. Dido525

Well the curve on the top is technically y=1.

12. CliffSedge

I think you need to switch x and y to find x-bar and y-bar. i.e. for x-bar it is integral of y dA, and for y-bar it is integral of x dA.
