What is a simple michine?
Simple machines are devices that makes work easier- changing size, direction, speed of force
What is an anometer used for?
An anemometer is a devise used to measure wind speed
What is the Hollerith's Automatic Census Tabulating Machine?
Invented in 1890, by Herman Hollerith, it was a way to speed up the tabulation of the US Census.
How do you get faster access?
if you have the proper high speed computer devise , as well as service provider , internally and or if you are using external Internet connection
Why did Herman hollerith the machine to read the card?
To speed up the 1890 census. The 1880 census using traditional hand counting methods had taken 8 years just to get the basic figures required by the constitution related to voting. It was estimated that without assistance of some kind the 1890 census would take much longer than 10 years, making its data useless. Using Hollerith's machines the entire 1890 census was complete in a single year!
What bureau of government first used punch cards to colect data?
The United States Census Bureau was the first government bureau to use punch cards for data collection. They began using punch cards in the late 19th century to process and tabulate census data. This technology greatly improved the speed and accuracy of data processing and became widely adopted by various government agencies and industries.
Can you use two wifi needing devices on 1 router?
You can use as many as you want. But if you have a 54mb wireless router, and one devise is using the 54mb then there is none left for the others. One devise will never use this much, just trying to get you to understand the Idea. Basically you could run 20 computers and if they are only download 1mb each plus the browser usage, there is no problem. All routers have different speeds, usually the more money the higher the speed.
Why do you have a survey?
Surveys are a way to derive conclusions about various properties of a population. Population need not refer to people but can be other living things or inanimate objects.The alternative to a survey is a census, in which observations are taken for every member of the population. Because of its size, a census is often very expensive and slow to process. A well designed survey can usually deliver estimates of the key variables that are very close to their true value at considerably greater speed and lower costs.Surveys are a way to derive conclusions about various properties of a population.

For example how long would it take to go around if you were a census person around the world?
Lets say that you were the ONLY census taker and had some sort of high speed way of getting from person to person and lets say it took you 5 minutes per person here is a small formula a= 6,706,993,152 * b=5. "A" being the current population and "B" the arbitrary time element.
Advantages of census over Sampling in Statistics?
There are several advantages of sampling over census (i.e. selection of wholepopulation for analysis).Firstly, the costs on sampling should be much lower than that on census. For example,for the government by-census (note: population census is usually conducted onceevery ten years and a by-census is conducted in the middle of the intercensal period),one fifth of the population is large enough to declare what the government wants toknow. There is no need to spend several times of dollars to interview the entirepopulation in the society.Secondly, a quality guru (Deming, 1960) argued that the quality of a study was oftenbetter with sampling than with a census. He suggested that, "Sampling possesses thepossibility of better interviewing(testing), more thorough investigation of missing,wrong , or suspicious information, better supervision, and better processing than ispossible with complete coverage". Research findings substantiate this opinion. Morethan 90% of survey error in one study was from non-sampling error1, and 10% or lesswas from sampling error2. (Donald et al., 1995)Thirdly, sampling can save the time. The speed of execution reduces the time betweenthe recognition of a need for information and the availability of that information.1 Non-sampling error is the error of research due to factors other than the sample size and samplingmethod, including non-response, bad communication with interviewees, measurement error, etc.2 Sampling error is the error during research due to the sample size and sampling method.
If the speed of an object does not change the object is traveling at what speed?
there's four speed. There are constant speed, average speed, increasing speed, and decreasing speed. choose one of them
Is instantaneous speed final speed?
No instantaneous speed is not final speed.
