The sum of all relative frequencies equals 1 because relative frequency represents the proportion of each category relative to the total number of observations. When you add up all proportions, they collectively reflect the complete dataset. Since every observation must fall into one of the categories, the total relative frequency accounts for all possibilities, thus summing to 1. This ensures that the distribution of frequencies accurately represents the whole.

How can you use relative frequencies to create a circle graph of data?
To create a circle graph (or pie chart) using relative frequencies, first calculate the relative frequency of each category by dividing the frequency of each category by the total frequency of all categories. Then, convert these relative frequencies into angles by multiplying each relative frequency by 360 degrees. Finally, draw a circle and partition it into segments based on these angles, ensuring each segment represents the proportion of each category in relation to the whole dataset.
Which figure always has equal angles and equal sides?
an equilateral triangle has all its angle and sides equal
If a quadrilateral is a parallelogram will it always have equal angles?
Diagonally opposite pairs of angles will always be equal, but the only time all angles in a quadrilateral parallelogram are equal is when that shape is a rectangle.
Which quadrilateral always has four right angles and all sides are equal?
A square
Is a rhombus always congruent?
All four sides are aways equal in length.
What is the sum of the percent frequencies for all classes will always equal?
It is always 100%.
Why is the sum of all the cumulative relative frequencies equal to 1?
By definition, the sum must be unity.
The sum of all the relative frequencies of a distribution will always add up to 1?
Yes they doHere are some properties of relative frequency:(a) The relative frequency of each outcome is a number between 0 and 1.(b) The relative frequencies of all the outcomes add up to 1..

Gene or allele frequency
What is the definition of relative social equality?
All people are equal
The first class in a relative frequency table is 50-59 and the corresponding relative frequency is 0.2What does the 0.2 value indicate?
The sum of the relative frequencies must equal 1 (or 100%), because each individual relative frequency is a fraction of the total frequency. The relative frequency of any category is the proportion or percentage of the data values that fall in that category. Relative frequency = relative in category/ total frequency It means a number in that class appeared 20% of the total appearances of all classes
How do you do an ogive chart?
You will need endpoints of your range (for example age: 12-14, 15-17. The endpoints are 14 and 17). You will also need the cumulative total of the relative frequencies (add all relative frequencies). -To find the relative frequency = value over total (ex, age 12-14, 51 have diabetes, 90 do not. The total of those having diabetes is 3800. So for the relative frequency of ages 12-14, it is 51/3800=0.01342. Do this for all ranges). -To find the Cumulative Frequency: add all these frequencies (separate for "yes" diabetes and "no" diabetes). Use endpoints of your range for the x-axis (horizontal axis). Then use the cumulative frequencies as your y-axis (vertical axis).
Are all the angles in a parellelogram equal?
All the angles in a parallelogram can be equal, but are not always.
If a polygon's sides are all equal will the interior angles be all equal?
yes always
What is the commulative property?
Cumulative is not a property. It refers counts (or frequencies) for all values less than or equal to the current value.
Opposite angles of all parallelograms are always?
opposite angles of all parallelograms are always equal.
Which figure always has equal angles and equal sides?
an equilateral triangle has all its angle and sides equal
