What is the specific significant digits in 0.0098?

Answer:

0.00900 has 3 significant figures, "9", "0", and "0". The significant figures are shown in bold. This is true because:

-All non-zero digits are significant (the nine)

-All zeroes trailing the first non-zero digits are NOT significant (the first three zeroes)

-If a number has a decimal point, all zeroes AFTER the last non-zero digit are significant (the last two zeroes). Therefore, it has 3 significant digits.

How many right angles in the letter K?

The letter K contains two right angles. A right angle is defined as an angle that measures exactly 90 degrees. In the letter K, there are two perpendicular lines meeting at a corner, each forming a right angle.

What number is xxv11?

XXVII in Roman Numbers is 27 in Arabic Numbers.

What is numeric value and example?

Numerical value = absolute value = a number's distance from zero on the number line.

For example, |3| = 3, and | -3| = 3. So we can say that -3 and 3 are 3 units from zero.

What does vXXX represent in Roman numerals?

In Roman numerals, "vXXX" is not a standard or valid notation. Roman numerals follow specific rules and conventions for their notation. Here is a brief explanation of how Roman numerals work:

  • I = 1
  • V = 5
  • X = 10
  • L = 50
  • C = 100
  • D = 500
  • M = 1000

When combining these symbols, there are rules such as:

Smaller numbers before larger numbers indicate subtraction (e.g., IV = 4).

Smaller numbers after larger numbers indicate addition (e.g., VI = 6).

The notation "vXXX" does not conform to these rules. Roman numerals are typically written in uppercase letters, and lowercase "v" is not standard.

If we correct the notation to "VXXX", it would represent 5 (V) followed by three tens (XXX), which is:

  • V = 5
  • XXX = 30

So, "VXXX" would be 5 + 30 = 35.

Do you add or multiply for area?

You have to multiply to find area you have to add to find perimiter

How many zeros are there in a terabyte?

There are 1000000000000 bytes in 1 terabyte, so there are 12 zeros in a terabyte.

This answer uses the modern convention where large number prefixes are implied to be based on powers of ten, rather than on powers of 2.

What is the mortality rate of gastritis in southeast asian?

The question cannot be answered since it ends in an adjective without the defining noun. Southeast Asian what: SE Asian men or SE Asian women or SE Asian children or SE Asian cats?

How long does the normal train take if the express takes 5 and half hours between cities and takes 3 out of 5 times less then the normal train?

5.5 = .60X

Then

5.5/.6 = X

then once you have x which is 3.3 hours do you hadd that to the 5.5 hours it takes the express to make 8.8 hours which is how long the normal train takes?

How much and what type of schooling did David Hilbert receive?

David Hilbert earned a doctorate from the University of Königsberg in Germany in 1885. See related Wikipedia link for more information.

What is the area of the base of the cylinder with the diameter of 8?

Diameter is 8, hence radius is 4

the base of a cylinder is also a circle. so we take the formula for area of a circle which isπr2

3.14 x (4)2= 3.14x 16= 50.24

How many different triangles exist so that any side-length is less than 4 units long and the sum of all three sides is equal to 5?

Let's ignore 'triangles' with sides of length zero. I assume that you mean triangles with sides of whole-number length; otherwise, the possibilities are infinite.

The sides have to add to five. There are only two ways of doing this:

1 + 1 + 3

1 + 2 + 2

Both of these possibilities satisfy the other constraint mentioned in the question.

How do you determine the optimum number of CNG refueling stations?

That will and has been determined by the market. If there is no demand, there will be no stations. EX: By government intervention one was opened in my area about 15 years ago. (There was some federal funding to get it started.) But in less than 5 years it was closed due to lack of use. This will be determined by demand. If more CNG vehicles are sold to something other than governmental operations, then some company will respond by installing them to make a profit.

What is the value of relative error if the absolute error is 10?

The relative error depends on the true value of the measurement. That information has not been provided.

What is the sequence to 2 9 5 13 10 19 17?

This is a two-phase sequence.

Add a number - start with 7 and increase by 1 at each addition.

Subtract a number - start with 4 and decrease by 1 at each subtraction.

2 + 7 = 9

................9 - 4 = 5

5 + 8 = 13

...............13 - 3 = 10

10 + 9 = 19

...............19 - 2 = 17

17 + 10 = 27

...............27 - 1 = 26

What is a multiplicative especially as it relates to a multiplicative inverse?

Multiplicative means pertaing or related to the mathematical opration known as multiplication.

HOW you can simulat the poisson random measure?

A simple way of generating poisson random numbers is given by Knuth, in his book "The Art of Computer Programming" in the chapter on Seminumerical Algorithms. I can't quote it directly here, due to copyright and plagarism limitations, but the Related Link below contains a reference to it.

How do you determine the decimal number in the binary system?

It's a bit like long division. The site that I linked below has a good explanation. You can also use specialty calculators, or the programming mode of the Windows calculator.
