What is TI-83 Plus?
Easy-to-use graphing calculator for math and science that lets students graph and compare functions, as well as perform data plotting and analysis. Its Flash™ ROM memory allows students to update and add software applications (apps).
What is the difference between a TI-84 and 83?
The Differences Another difference is that the TI-84 Plus can be connected to a computer via a USB port while the TI-83 plus does not come with a USB port. In the real world this makes the TI-84 Plus about 2x as fast as the TI-83 Plus. The TI-83 also has 160 KB of storage whereas the TI-84 Plus has 480 KB.

How does excel calculate variance?
Sample variance formula in Excel
- Find the mean by using the AVERAGE function: =AVERAGE(B2:B7)
- Subtract the average from each number in the sample:
- Square each difference and put the results to column D, beginning in D2:
- Add up the squared differences and divide the result by the number of items in the sample minus 1:
Is the TI-83 good for calculus?
The TI-83 Plus graphing calculator is a great entry-level calculator for middle and high school students taking math and science courses such as Pre-Algebra, Algebra 1 & 2, Trigonometry, Calculus, Statistics, Biology, Chemistry, and Physics.
What does S mean in probability?
The sample space S for a probability model is the set of all possible outcomes. For example, suppose there are 5 marbles in a bowl. One is red, one is blue, one is yellow, one is green, and one is purple.
What year did the Texas Instruments TI-83 come out?

Does the TI-83 support assembly language?
The TI-83 was the first calculator in the TI series to have built in assembly language support. The TI-92, TI-85, and TI-82 were capable of running assembly language programs, but only after sending a specially constructed (hacked) memory backup. The support on the TI-83 could be accessed through a hidden feature of the calculator.
What is the difference between the TI-83 and Ti- 83 plus?
The TI-83 Plus was designed in 1999 as an upgrade to the TI-83. The TI-83 Plus is one of TI’s most popular calculators. It uses a Zilog Z80 microprocessor running at 6 MHz, a 96×64 monochrome LCD screen, and 4 AAA batteries as well as backup CR1616 or CR1620 battery. A link port is also built into the calculator in the form of a 2.5mm jack.
