Qq 10.6.8 Update

Python 3.6.8 was the eighth and last maintenance release of Python 3.6.

• More than just a video downloader, Apowersoft Video Downloader for Mac features a powerful video converter that offers the ability to convert videos to all popular file formats for devices, such as iPad, iPod touch, PSP, iPhone, Samsung Galaxy, Kindle Fire, HTC and many others.
• All downloads are hosted by Apple. Links on this site take you directly to Apple’s download pages. This is not an official Apple website. Please consider donating to help maintain it.

There are now newer security-fix releases of Python 3.6 that supersede 3.6.8 and Python 3.8 is now the latest feature release of Python 3. Get the latest releases of 3.6.x and 3.8.x here. Python 3.6.8 is planned to be the last bugfix releasefor 3.6.x. Following the release of 3.6.8, we plan to provide security fixes for Python 3.6 as needed through 2021, five years following its initial release.

OS X Mountain Lion (version 10.8) is the ninth major release of macOS, Apple Inc.' S desktop and server operating system for Macintosh computers. OS X Mountain Lion was released on July 25, 2012 for purchase and download through Apple's Mac App Store, as part of a switch to releasing OS X versions online and every year, rather than every two years or so.

Among the new major new features in Python 3.6 were:

• PEP 468, Preserving Keyword Argument Order
• PEP 487, Simpler customization of class creation
• PEP 495, Local Time Disambiguation
• PEP 498, Literal String Formatting
• PEP 506, Adding A Secrets Module To The Standard Library
• PEP 509, Add a private version to dict
• PEP 515, Underscores in Numeric Literals
• PEP 519, Adding a file system path protocol
• PEP 520, Preserving Class Attribute Definition Order
• PEP 523, Adding a frame evaluation API to CPython
• PEP 524, Make os.urandom() blocking on Linux (during system startup)
• PEP 525, Asynchronous Generators (provisional)
• PEP 526, Syntax for Variable Annotations (provisional)
• PEP 528, Change Windows console encoding to UTF-8
• PEP 529, Change Windows filesystem encoding to UTF-8
• PEP 530, Asynchronous Comprehensions

Please see What’s New In Python 3.6 for more information.

• PEP 494, 3.6 Release Schedule
• Report bugs at https://bugs.python.org.
• Help fund Python and its community.

• The binaries for AMD64 will also work on processors that implement the Intel 64 architecture. (Also known as the 'x64' architecture, and formerly known as both 'EM64T' and 'x86-64'.)
• If installing Python 3.6 as a non-privileged user, you may need to escalate to administrator privileges to install an update to your C runtime libraries.
• There are now 'web-based' installers for Windows platforms; the installer will download the needed software components at installation time.
• There are redistributable zip files containing the Windows builds, making it easy to redistribute Python as part of another software package. Please see the documentation regarding Embedded Distribution for more information.

• For Python 3.6 releases, we provide two binary installer options for download. The default variant is 64-bit-only and works on macOS 10.9 (Mavericks) and later systems. We also continue to provide a 64-bit/32-bit variant that works on all versions of macOS from 10.6 (Snow Leopard) on. As of 3.6.8, both variants now come with batteries-included versions oF Tcl/Tk 8.6 for users of IDLE and other tkinter-based GUI applications; third-party and system versions of Tcl/Tk are no longer used. Consider using the 10.9 64-bit-only installer variant unless you are building Python applications that also need to work on older macOS systems. Binary extension modules (including wheels) built for earlier versions of 3.6.x with the 10.6 variant should continue to work with either 3.6.8 variant without recompilation.
• Both python.org installer variants include private copies of OpenSSL 1.0.2. Please carefully read the Important Information displayed during installation for information about SSL/TLS certificate validation and the Install Certificates.command.

Hi Shelly,

I like this problem a lot partly because there are so many ways to solve it. If your son knows some algebra he can solve it using the algebraic technique used on the algebra.com web site.

This problem can however be presented to a student as soon as he or she learns to do arithmetic with decimals. I think this is wonderful problem to give to a group of such students and have them work on a joint solution. I am going to use the numeric values in the problem referred to above and refer to the three chickens as a rooster, a hen and a chick with the rooster the heaviest and the chick the lightest.

The rooster and the chick weigh 8.5 kg and the hen and chick weigh 6.1 kg. Thus the rooster weighs 8.5 - 6.1 = 2.4 kg more than the chicken. But the rooster and the hen together weigh 10.6 kg. Hence, on the scale with the rooster and the hen replace the rooster by an identical hen and a 2.4 kg weight. The scale will still read 10.6 kg. Remove the 2.4 kg weight and the scale reads 10.6 - 2.4 = 8.2 kg. Thus two chickens weigh 8.2 kg. What does one chicken weigh?

A third solution comes from an observation. What does 10.6 + 8.5 + 6.1 = 25.2 kg represent in terms of roosters, hens and chicks?

I hope this helps,
Penny

I think I might know what you mean, and if so, it's not a ratio problem but a problem in linear algebra.

Are the data in a form like:

X and Y together weigh A
Y and Z together weigh B
Z and X together weigh C ?

This gives rise to the linear equation system

Qq 10.6.8 Version

x + y = A
y + z = B
x + z = C

Q106.8

This isn't in triangular form, so has no obvious 'weak spot.' But you can (for instance) subtract the second equation from the first to get a second equation in x and z; then add this to the third to eliminate z.
