What number aa is 25% of 64? An equation is a=0.25*64. The solution is a=16. Then check.
64 / 16 = 4. So 16 is the solution.
<span>68=-16t2+64t+8
16t2-64t+60=0
4t2-16t+15=0
(2t-5)(2t-3)=0
t=5/2 or 3/2
The object is at 68 feet after 3/2 secs, and returns to 68 feet after another second..</span>
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.
Hey there again,
The first step is to put the data in order, as shown in the diagram below
Five summaries of Town A
Lowest Value = 10
Lower Quartile, = 16.5 (The value falls between 16 and 17)
Median, = 25
Upper Quartile, = 40 (The middle value between 38 and 42)
Highest value = 42
Five summaries of Town B
Lowest value = 0
Lower Quartile, = 4 (The middle value between 0 and 8)
Median, = 9
Upper Quartile, = 20 (The middle value between 19 and 21)
Highest Value = 30

No, to be a square each side has to be equal. but all squares are rectangles.
