Top 20 Texas Instruments TI-84 Plus Calculator - Page 2 Questions & Answers

You do the operation to get a decimal number. Isolate the integer part (to the left of the decimal point) Convert the non integer part (decimal part) into a fraction. Write the result as (integer part) (fraction part) 3/2=1.5 Integer part is 1, decimal part is 0.5 0.5 as a fraction is 1/2 3/2= 1 1/2

It is already rounded to the nearest integer.

If you only cleared RAM, a program that was loaded no longer resides in RAM, but if it was archived, it should still be available. If you cleared all Including Archives, then it is lost.

What light? The TI-84 doesn't have a light.

Milliliter is a unit of volume, milligram is a unit of mass (or weight). There is no direct conversion between them. 5 mg of water occupies 5 ml. 5 mg of gold occupies about about a quarter of a ml.

There is no such button. The factorial function is in the probability submenu of the math menu. Press MATH left-arrow 4 to access the factorial.

See image below

You're probably trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

You have a dimension mismatch if (for example) you are doing 2-var stats and the two lists do not have the same length. You can also have mismatch with matrices.

8 and 10. If this is homework, be sure to show your work.

No button does that, nor a CATALOG command. But do check in the CATALOG (2nd 0).

Look under Math>Probabilities. Symbol is nPr

TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

Gram is a unit of mass (or weight). Teaspoon is a unit of volume. One teaspoon of water will weigh about 4.9 grams. One teaspoon of gold will weigh over 90 grams.

V = (pi)(r square)(h) V= Volume (the amount we need to calculate) pi = 3.14... r = radius of cylinder (remember this is half that of the circumference) h = height of cylinder To make it easier for you below are the figures for the Cylinder. Radius= 11.5 inches Height = 17 inches. Now use the formula above to calculate it. For the Jelly Bean its, Radius = 0.25 inches Height = 0.5 Use the same formula above for jelly bean as well. Once you have both figures, divide Volume of Jar by Volume of Jelly e.g. VolumeofJar/VolumeofJelly AND VOILA, you have the amount of jelly beans in a jar (Round the figure out) Cheers!

Do you mean that you get a rectangle? Check your equations.

Use the equivalent definition cot(x) =1/ tan(x)

Milligram is a unit of mass. Milliliter is a unit of volume. Comparing the two is like trying to compare pounds and gallons. One ml of water will weigh 1000 mg. One ml of gold will weigh nearly 20000 mg.

TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible. If that doesn't do it, please respond to this post and we'll go from there.
