When I run the following codes, I get an alert 'readpage' overrides nothing in line 42, the override fun readpage() in class eBook. Why is that and how do I fix this? I am learning kotlin and following a tutorial from udacity. I have tried to figure this out by myself for 2 weeks and spending 10+ hours but still don't know why?

I am new here. I'm learning web programming, and now I'm a bit stuck with Javascript. I want to validate that, when a new object is added to an array, it has all the required keys. I have shared below an array object, an example object with all the keys, and an object that does not have all the required keys. I tried to use Object.keys() to compare the keys of an array object, with the object to be input. However, unfortunately both objects that have all the keys and objects that do not have all the keys are taken as incomplete. I cannot add any new objects, even though they have all the keys that the other objects in the array have. Does anyone know where I am going wrong? I would be very grateful for help.

Thanks and best regards to all!

I am trying to shade the 0.025 and 0.975 quantiles on this graph that has three lines. I have tried geom_area, geom_ribbon, and I cannot highlight every quantile in every line.

Please note that "y" was ignored in this density graph.

I am trying to run some zero-inflated GLM's using the zeroinfl function, but a lot of them are giving me negative intercepts which don't make sense for my variables. Is there a way to set the intercept above zero? Thank you! For example:

Heyo,

I'm trying to use CSS Grids, to layer text over images in a grid. Basically I want to put the captions over the images. However, this does not work. I've tried searching the web, the main answers are about positions: but this doesn't seem to work either.

In the snippet I used background colors instead of images. I want the full text to go over these images.

I am working on an assignment where I am creating a webpage about sharks and I need to know how I can center my images. I have already tried the align attribute in my code and my images are still not centered. I would like the images to be in the center of the screen.

Here is my image code:

Here are the images on the actual webpage:

Here is my code (if needed)
