A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What is 2k rule?

The 2k or 2 to K rule is used to determine the number of classes for a frequency distribution. The 2k rule should be used as a guide more than a dictator of determining the number of classes for a frequency distribution.


Why t-distributions tend to be flatter and more spread out than normal distribution?

The shape of a t distribution changes with degrees of freedom (df). As the the df gets very large the shape of the t distribution will begin to look similar to that of a normal distribution. However, the t distribution has more variability than a normal distribution; especially when the df are small. When this is the case the t distribution will be flatter and more spread out than the normal distributions.


What is the shape of a frequency distribution with an arithmetic mean of 800 pounds median of 758 pounds and a mode of 750 pounds?

As the mean is greater than the median it will be positively skewed (skewed to the right), and if the median is larger than the mean it will be negatively skewed (skewed to the left)


A normal distribution has a mean of ยต = 50 with ฯƒ = 10. What proportion of the scores in this distribution are greater than X = 65?

Scores on the SAT form a normal distribution with a mean of ยต = 500 with ฯƒ = 100. What is the probability that a randomly selected college applicant will have a score greater than 640? โ€‹


Why is the Normal Distribution called normal?

Suppose you could call it the Gaussian Distribution or the Laplace-Gauss (not to be confused with the Laplace distribution which takes an absolute difference from the mean rather than a squared error)... however the Brits had no one to name this distribution after (not the German and French names) and because it is the ubiquitous distribution they just called it... well the NORMAL!!

What is the advantage of relative frequency distribution vs distribution frequency?

These help to distribute the frequency much better than the latter. The noise might not be as loud or boisterous this way.


Why would relative frequency be better than frequency while comparing two different groups?

you are aw some * * * * * Sadly you are not since you can't even spell the word. Relative frequency would be better because the two groups may be of different size.


Why is a cumulative frequency distribution so much more informative than just the relative frequency distribution?

It is not. It depends on what question you want to answer. They are both equally informative, but in different circumstances.the CRFD can be used to determine a summary of proportion of observations that lies above(or below) a particular value in a data set which the RFD cannot


What is commulative frequency distribution?

The cumulative frequency distribution for a value x of a random variable X, is a count of the number of observations in which X is less than or equal to x. The cumulative frequency distribution for a value x of a random variable X, is a count of the number of observations in which X is less than or equal to x. The cumulative frequency distribution for a value x of a random variable X, is a count of the number of observations in which X is less than or equal to x. The cumulative frequency distribution for a value x of a random variable X, is a count of the number of observations in which X is less than or equal to x.


What is a radio wave's relative wavelength and frequency is?

The wave length and frequency of course vary, the frequency ranges from 3kHz to 300 GHz. The wavelengths are longer than infrared.


What does a cumulative relative frequency of .4 mean?

If the cumulative relative frequency when the variable X takes the value x, it means that 0.4 (or 40%) of the values of the variable X are less than or equal to x.


What is 2k rule?

The 2k or 2 to K rule is used to determine the number of classes for a frequency distribution. The 2k rule should be used as a guide more than a dictator of determining the number of classes for a frequency distribution.


What is the difference in relative frequency between red and violet light?

Violet light has a higher frequency than red light by roughly a factor of 2.


Why normal distribution is better than other distributions?

It may not be better, but there is a lot of information on the normal distribution. It is one of the most widely used in statistics.


Why does the frequency domain better than the spatial domain?

complexity is low than spatial


How are histograms and bar graphs different?

In a bar graph, the height of the bars is relative to the frequency. In a histogram, the area of the bars is relative to the frequency. Because it deals with area, the label on the y-axis is "frequency density" rather than just "frequency"


What is the problem if frequency of computer is low and random access memory is high?

It's not a problem. But it's better when FSB frequency is higher than RAM frequency.
