No.
The relative frequency of a class is the frequency of the class divided by the total number of frequencies of the class and is generally expresses as a percentage.
To calculate cumulative frequencies, start by organizing your data in a frequency distribution table. For each class interval, add the frequency of that interval to the cumulative frequency of the previous interval. Begin with the first interval, where the cumulative frequency is simply its frequency, and continue adding each subsequent frequency to the cumulative total. This process will give you a running total of frequencies up to each class interval.
An ogive is a type of graph that is used to represent the cumulative frequencies for the classes in a frequency distribution. This type of graph can also be known as a cumulative frequency graph. The cumulative frequency is the sum of the frequencies accumulated up to the upper boundary of a class in the distribution.
Frequencies typically refer to counts, or "how many". If you wanted to know the frequencies of students in a school by gender, you would simply be asking about "how many" boys and how many girls there are.

No, a frequency polygon is a type of data visualization that uses line segments to connect points representing the frequencies of different classes. It shows the distribution of data values, but it does not necessarily represent the actual class frequencies.
You cannot - except in very trivial cases.

The y-axis of an ogive is always the cumulative frequencies while the x-axis is the class boundaries.
Usually because the frequencies at one or both ends of the distribution are very small.

Step 1: Find the midpoint of each interval. Step 2: Multiply the frequency of each interval by its mid-point. Step 3: Get the sum of all the frequencies (f) and the sum of all the fx. Divide 'sum of fx' by 'sum of f ' to get the mean. Determine the class boundaries by subtracting 0.5 from the lower class limit and by adding 0.5 to the upper class limit. Draw a tally mark next to each class for each value that is contained within that class. Count the tally marks to determine the frequency of each class. What is this? The class interval is the difference between the upper class limit and the lower class limit. For example, the size of the class interval for the first class is 30 – 21 = 9. Similarly, the size of the class interval for the second class is 40 – 31 = 9.

No, fundamental frequencies and overtones are not typically referred to as resonance frequencies. Resonance frequencies are specific frequencies at which an object naturally vibrates or oscillates when subjected to external forces. Fundamental frequencies are the lowest frequency at which an object can vibrate, while overtones are multiples of the fundamental frequency.
