Answer:
A better option to express the results will be a cumulative frequency curve.
Step-by-step explanation:
At the moment, the moment, the question does not have a histogram, so we will explain the advantages of a frequency distribution curve or polygon.
The Cumulative Frequency Curve allows data to be interpreted continuously. The cumulative frequency prevents "gaps" that are found in the histograms. For instance, a histogram does not provide a frequency distribution of a certain type of data. In addition, the curves clarify better the trends in the data set. Furthermore, large data can be compressed and summarized in a compact form by using the distribution in the data set.
Answer:
The value of x is inversely proportional to the difference of <em>a</em> and <em>b</em>.
Step-by-step explanation:
The given expression is 
We factor the left hand side to get:
We divide both sides by: a-b
Observe that the difference of a and b is in the denominator.
The whole is of the form: 
The value of x is inversely proportional to the difference of <em>a</em> and <em>b</em>.
You add 6+21=27 and then add 27+4 which equals 31
Answer:
Step-by-step explanation:
Answer:
y = 14
Step-by-step explanation:
proportional relation: y = kx
only y = 14x has the situation where constant is 14 (k=14)
