@RZ923 Yes, absolutely!! 🙂 Thank you!

@divinedolphin You were right to initially think that the decimal was \(0.251111\overline{2222}\ldots.\) 🙂 The multiple \(2\)'s come from the overlap of the first set of \(1\)'s in \(0.\textcolor{blue}{00}\overline{\textcolor{red}{1111}111111}\ldots\) plus the second set of \(1\)'s in \(0.\textcolor{blue}{00}\textcolor{red}{0000}\overline{1111}\ldots \)

The first set of \(1\)'s is shifted over to the right by two spaces, allowing the \(25\) to appear.
The second set of \(1\)'s is shifted to the right by \(6\) spaces, allowing the four \(\textcolor{red}{\text{red } 1}\)'s from the \(0.\textcolor{blue}{00}\overline{\textcolor{red}{1111}111111}\ldots\) to show through.
And the remaining \(2\)'s come from the places that have \(1\)'s in both the \(0.\textcolor{blue}{00}\overline{\textcolor{red}{1111}111111}\ldots\) and the \(0.\textcolor{blue}{00}\textcolor{red}{0000}\overline{1111}\ldots \)

@debbie Fixed 🙂 🔧 🔧

@divinedolphin Oops! Thank you so much. I'm very sorry for this error and for the confusion. I've just fixed this, so the correct multiple-choice answer of 15 should work now. 🙂

@tidyboar Ooooohhh!!!

I wish I could you give you bonus points for catching errors. 🙂 (And bonus points to everyone else who very diligently alerts us of errors.) Without you, the course wouldn't be as good as it is!

Thank you SO much! I will pass this along to the marketing team. 👍 👍

@The-Blade-Dancer Oh, did you see the "Review Results" button at the bottom of the screen that shows your score...? Clicking on this button will show you the page that has your answers and the solutions. 🙂

If you missed that button and close the window by accident, don't worry, you can also review your results by clicking a link that is emailed to you.

The email would look like this in your inbox:

2020-amc-8-mock-inbox-results-email.png

And inside that email would be a link that opens a browser window displaying your score and the "Review Results" button again.

Could you please try checking your email to see if you got the link? If you really still can't get your results, then there is still a way I can get them to you. 🙂

@Kevin-Li said in AMC Mock Test 2020:

for number 22, it says independently, 1/3 chance of getting COVID. It has not been specified that you have to first meet a person with covid, then have a 1/3 chance of getting it, in fact since it says INDEPENDENTLY, it means it cannot depend on another factor such as the 50 percent chance of getting COVID

Hi Kevin,

You are right on both of these comments! We're very sorry for the error in the diagram not showing up. I've fixed this and it should work now. (You can also the diagrams in this printable .pdf) 🙂 Thanks so much for your patience.

Thanks also for pointing out the unclear conditions in question #22. We will refine the question to indicate that we are concerned only with the probability of catching COVID from the three people in the problem.

We really appreciate your patience and for letting us know. Please tell us if you see anything else!

🙂

The answer choice originally read as "\(\textcolor{blue}{\overline{AB}} \) and \(\textcolor{blue}{\overline{BC}},\)" and you can see the order of the vertices: in \(\overline{AB},\) the first vertex, \(A,\) is at the right angle and the second vertex, \(B,\) is at the purple angle. In \(\overline{BC},\) the first vertex, \(B,\) is at the purple angle, and the second vertex, \(C,\) is at the right angle.

It would be more consistent to name them starting with the first vertex being at the right angle and the second vertex at the purple angle.

This is what @RZ923 was talking about with regards to the order of the vertices when naming a line segment.

You can also see from the similar triangles \( \bigtriangleup ABD \) and \(\bigtriangleup CBE\) that the side \(\overline{AB}\) corresponds to the side \(\overline{CB}.\) 🙂

Hooray! @debbie is getting through the to-do list!

@RZ923 Lolol

@RZ923 Lol... maybe I should write a description too haha

lol 🤣

@The-Blade-Dancer Oh, please don't! We want you to let us know, because we will get to all of these fixes someday, I promise! 🙂
