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 is significant figures or numbers?
"Numbers is just what you think. any combination of 0-9. for example: 0, 5, 312312033331984912841, pi, sqrt(2), sin(3), ... all of those are numbers. Now, when you talk about significant figures you are USUALLY talking about measurements. For example: How far did you walk today? If you answered 1 mile. I am willing to bet you did not walk EXACTLY 1 mile. But somewhere between 1/2 mile to 1 1/2 miles. Now, if someone said they walked 1.1 miles. They probably used a measuring device and it is accurate to say 1.05 to 1.15 miles. Similarly if they say that they walked 1.1134 miles, then it is actually between 1.11335 and 1.11345 miles that they actually walked, because the instrument they used was only accurate to the ten-thousand's of a mile. So, to count significant figures you do the following 1) Count all non-zero digits. 2) Count all 0's BETWEEN 2 non-zero digits 3) count all 0's AFTER a decimal if it is ALSO after a non-zero digit (eg. 0.003 only has 1, but 0.0030 has 2)." The number of significant digits is the number of digits in a measurement that are statistically justified. This number is solely defined by the degree of uncertainty on the measurement. If your measurement is 5.70 +/- 0.01 you have three significant digits. If your measurement is 56.798 +/- 0.002 the number of significant digits is 5. Note that leading zeros do not count (0.00000078 = 7.8 E-7)
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 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.
How many significant digits are in the time measurement 0.0036 s?
Two of them and they are 3 and 6
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.
Is 1.39174 a rational number?
Any time a number has a finite number of digits, it is rational.
How do you know if a number is in the 9 times table?
if you add the digits of the number such as 81 8+1=9 every time, the digits of the number will add up to 9
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.
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 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 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.
