How many digits in numeric system?

It varies depending on the base you are using. The standard is the decimal system (because of the 10 fingers on our hands) 0-9. Some other used systems (especially for computers) are binary 2, octal 8, hexadecimal 16 using the digits: 0-9,A-F.

What does houscarl mean?

Depending on the country involved and the period of history housecarls served in various roles, including bodyguards to kings, soldiers and administrators. They flourished from around the 11th century through the 13th. For more information please see the wikipedia article.

How many 3 digit numbers are there show rough work?

The largest 3-digit number=999

the smallest 3-digit number=100

total number of 3 digit number=(999-100)+1

=899+1=900

What first number in an ordered pair that tells the difference to move right or left?

It is called the abscissa, or the x-coordinate. The second number, which tells up and down distance, is called the ordinate.

Is stars shining an example of s continuous variable?

No, it is a continuous process but not a continuous variable.

The magnitude of star-shine, across all stars is a continuous variable. The magnitude of a star's shine over time is a continuous variable.

What is nominal executive?

A nominal executive refers to a position in government, typically the head of state, who holds a largely ceremonial role with limited actual power in decision-making and governance. This figure often represents the state in official matters but exercises little to no authority over the day-to-day operations of the government. In contrast, real executive power is usually held by another entity, such as a prime minister or cabinet, who carries out the functions of governance. Nominal executives are common in parliamentary systems, where the monarch or president may serve primarily as a symbolic leader.

How do you beat the final card in 007 everything or nothing?

how to beat it is to go threw the control room kill everyone in your sight and turn off each switch. the go outside and you'll find him waiting in a machine gun turret shoot that with a rcoket. you have to make to the controls without getting fried by the fire that is coming out the end of it. be careful the rocket might take off without warning if u make it to the controls without getting fried by the fire and shut down the last rocket you will win the game. by, anontmous how to beat it is to go threw the control room kill everyone in your sight and turn off each switch. the go outside and you'll find him waiting in a machine gun turret shoot that with a rcoket. you have to make to the controls without getting fried by the fire that is coming out the end of it. be careful the rocket might take off without warning if u make it to the controls without getting fried by the fire and shut down the last rocket you will win the game. by, anontmous

How do you get a median from an even amount of numbers?

for eg 6 numbers: 1,2,3,4,5,6 median = 3+4/2 =3.5

^

take the 2 middle numbers, add them, then divide by 2=3.5(work bellow)

^

3+4=7 7 divided by 2= 3.5

What is the difference between probability distribution functions and probability density functions?

Probability density function (PDF) of a continuous random variable is a function

that describes the relative likelihood for this random variable to occur

at a point in the observation space.

The PDF is the derivative of the probability distribution (also known as

cummulative distriubution function (CDF)) which described the enitre range of values

(distrubition) a continuous random variable takes in a domain.

The CDF is used to determine the probability a continuous random variable occurs any (measurable) subset of that range.

This is performed by integrating the PDF over some range (i.e., taking the area under of CDF curve between two values).

NOTE: Over the entire domain the total area under the CDF curve is equal to 1.

NOTE: A continuous random variable can take on an infinite number of values. The probability that it will equal a specific value is always zero.

eg. Example of CDF of a normal distribution:

If test scores are normal distributed with mean 100 and standard deviation 10. The probability

a score is between 90 and 110 is:

P( 90 < X < 110 ) = P( X < 110 ) - P( X < 90 )

= 0.84 - 0.16 = 0.68.

ie. AProximately 68%.

Types of sampling techniques?

It is a sampling method in which units are selected based on easy access/availability. The disadvantage of convenience sampling is that the units that are easiest to obtain may not be representative of the population. For example products on top of a box of parts may be a different quality from those at the bottom, people who are at home when the market researcher calls may not be representative of the entire population. It is also called as Accidental Sampling.

What does farfegnugen mean?

How many 36's can you roll with two dice?

None.

Two ordinary dice can only sum to 12 and so you cannot roll a 36.

What is the formula for finding the circumference of a circle when the diameter is given?

The formula is:

Circumference = (diameter) x (pi)

"Pi" = approximately 3.14159 26535 89792 (rounded)

If you use 3.14, your answer is within about 0.05% of the truth, on the low side.

If you use 22/7, your answer is within about 0.04% of the truth, on the high side.

What do mean middlan mode mean?

(Assuming you mean "median" when you say "middlan..."

Mean, median, and mode are all math terms. Mean is a certain type of way to get an average in a set of data.

The median number in a set of data is the number that is in the middle of all the rest when they are all lined up from least to greatest.

The mode numbers in a set of data are the numbers that occur most often ("Mode" comes from the French word that means "in fashion"- think of it this way: if there are a lot of numbers that are the same, it means that those numbers are "popular" and that they are "in fashion".)

For example:

Look at this set of data that is already organized from least to smallest.

1 3 3 4 5.5 7 10 10 12 14 17

The median would be 7, as it is right in the middle. (If there is an even amount of numbers, find the middle two and find the exact middle of those two.)

The mean is about 7.8. I got this by adding all of the numbers(86.5, in this case) and then dividing the sum by the number of numbers (11).

The mode would be both 3 and 10, as they both have the same and the greatest amount of numbers. Or you could write none and just say why- that there is a mode number but there is more than one number that is the "mode"

How would you get a random sample of 15 sheep to check for ticks on a farm of 250 sheep?

Gather all of the sheep who live on the farm into a corral. Then, choose fifteen of them, regardless of age, size, health or any other differentiating feature.
