Answer:
The relative frequency is found by dividing the class frequencies by the total number of observations
Step-by-step explanation:
Relative frequency measures how often a value appears relative to the sum of the total values.
An example of how relative frequency is calculated
Here are the scores and frequency of students in a maths test
Scores (classes) Frequency Relative frequency
0 - 20 10 10 / 50 = 0.2
21 - 40 15 15 / 50 = 0.3
41 - 60 10 10 / 50 = 0.2
61 - 80 5 5 / 50 = 0.1
81 - 100 <u> 10</u> 10 / 50 = <u>0.2</u>
50 1
From the above example, it can be seen that :
- two or more classes can have the same relative frequency
- The relative frequency is found by dividing the class frequencies by the total number of observations.
- The sum of the relative frequencies must be equal to one
- The sum of the frequencies and not the relative frequencies is equal to the number of observations.
Answer:
3 4/5
Step-by-step explanation:
just add the whole number then add the numerator then the denominator stay the same
Answer:
5
Step-by-step explanation:
To find the slope, rearrange the terms of this equation to y=mx+b form, where m is the slope.
Original equation: 5x-y=2
Subtract 5x to both sides: -y = -5x+2
Multiply both sides by -1: y = 5x-2\
This gives us the slope, which is equal to 5.
