A number is exempt from the use of significant digits when it is a counted quantity, such as the number of students in a classroom or the number of apples in a basket. Counted numbers are considered exact values, meaning they have an infinite number of significant digits. This is because they do not involve measurement uncertainty.

How many significant digits are in the time measurement 0.0036 s?
Two of them and they are 3 and 6
A jet flew 1307 mi in 2.35 hr What was the average speed?
Speed by definition = distance/time; in this instance 1307 mi/2.35 hr = 556 mi/hr, to the justified number of significant digits.
What rule must be used to find the number of strings of four decimal digits that do not contain the same digit twice?
It is the number of combinations of four numbers where the number of available digits starts at 10 and reduces by 1 each time.
What is all the combations for 1234567890 only using four at a time?
To find all the combinations of the digits 1 through 9 and 0 taken four at a time, you would calculate the number of ways to choose 4 digits from a set of 10. This is done using the combination formula ( C(n, k) = \frac{n!}{k!(n-k)!} ), where ( n ) is the total number of digits (10) and ( k ) is the number of digits to choose (4). Thus, ( C(10, 4) = \frac{10!}{4!(10-4)!} = 210 ). Therefore, there are 210 different combinations of these digits taken four at a time.
What 3 digits have the same sum and product?
Any number because one time anything equal the number you put down.
How do you write 484600 in scientific notation?
4.84600E5 (4.84600 time 10 to the power of 5) ... or depending on the actual precision it might be 4.8460E5 or 4.846e5 --- as written it is not clear if the last two digits in the number are significant digits or not.
Can you have different vacation policies for exempt versus non-exempt employees?
It is not a good policy to provide different benefits to different employees regardless of their employment status (exempt, non exempt, full time, part time). A good rule is to give vacation after a specific number of days had been worked.
How do you know if a number is in the 9 times table?

Is 1.39174 a rational number?
Any time a number has a finite number of digits, it is rational.

What s.f. means in math?
significant figures. For any number, the sf is the number of digits from the first non-zero digit to the last non-zero digit. Any zeros within that range ARE counted. So, for example, 1.23000 sf = 3 1.0230 sf = 4 00567.5 sf = 4 5.000000001 sf = 10
A jet flew 1307 mi in 2.35 hr What was the average speed?
Speed by definition = distance/time; in this instance 1307 mi/2.35 hr = 556 mi/hr, to the justified number of significant digits.
What is the differences between a significant figure and decimal place?
A decminal place is simply the number of digits to the right of the decimal in a number. For instance, 37.5834 has four decimal places. In contrast, a significant figure is the number of digits on either side of the decimal place that can be counted as accurate in a calculation. Significant figures are used to determine how accurate a calculation is based on how accurate the measurements are. Significant figures are determined by counting the number of significant figures in the numbers given in a problem (usually in chemistry or physics) then using the lowest count found. Here's an example: "calculate the average velocity of a car that has travelled 45 km in 60 minutes." The number "45" has two significant figures while the number "60" has one significant figure. Therefore, when calculating the velocity (45/60), the answer can have only one significant figure: 0.8 km/min. However, if the time was written as "60.0" minutes, then this number would have three significant figures and the answer could have two significant figures (0.75 km/min) because the number "45" had two significant figures.
What number it digits decrease by 2 from the thousands place to the ones place and each number is even number?
If the digits go from the thousands place to the ones place then we need to use 4 digits. Because the digits are all even, we are forced to use the 4 even digits (2, 4, 6 and 8). As they decrease by 2 each time, the only option for ordering them is greatest to lowest. Therefore, the number described in the question is 8,642.
How long can I file exempt on my taxes?
You can file as exempt on your taxes for one year at a time.
What rule must be used to find the number of strings of four decimal digits that do not contain the same digit twice?
It is the number of combinations of four numbers where the number of available digits starts at 10 and reduces by 1 each time.
How do you check whether the given number is Armstrong or not?
First, review the definition of an Armstrong, or narcissistic, number:"...is a number that is the sum of its own digits each raised to the power of the number of digits."So, you need to count the digits (to know what power to use), and extract the individual digits. This can be done in several ways; for example, you might convert the number to a string. In Java:String numberAsString = "" + number;Now it should be easy to figure out the length of the String (use the .length() method), and to extract the individual digits - check the methods available for strings. Then you need to convert the digits back to numeric data.Another way is to get one digit at a time, starting from the right, using the "%" operator.For example, 153 % 10 is equal to 3. Divide the number, 153, by 10 (integer division), then repeat to get the remaining digits. You might store the digits to an array.First, review the definition of an Armstrong, or narcissistic, number:"...is a number that is the sum of its own digits each raised to the power of the number of digits."So, you need to count the digits (to know what power to use), and extract the individual digits.
