Answer:
The set U includes all positive integers from 1 to 20.
a)
<u>x is subset U and 14 < x ≤ 23, then x is:</u>
- x = {15, 16, 17, 18, 19, 20}
b)
<u>x is subset U and includes multiples of 4, so x is:</u>

There is no mode distance, so take the middle number around 7-8. maybe 7.5.
position 4
7.5 km
Not entirely sure, let me know if there's an error and I will fix it.
Answer:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 52 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 52 is 100%, so we can write it down as 52=100%.
4. We know, that x is 20% of the output value, so we can write it down as x=20%.
5. Now we have two simple equations:
1) 52=100%
2) x=20%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
52/x=100%/20%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 20% of 52
52/x=100/20
(52/x)*x=(100/20)*x - we multiply both sides of the equation by x
52=5*x - we divide both sides of the equation by (5) to get x
52/5=x
10.4=x
x=10.4
now we have:
20% of 52=10.4
Step-by-step explanation:
2). mean: 2.2, median: 7 , mode: 7 , Range: 17
3) mean: 1.75, median:2, Mode:7, Range: 18
4) mean: 3.67, Median: 4, Mode:8, Range: 12
5) Mean:5, Median:5, Mode: 5 and Range: 5
In the given question it is important to take note of every minute details that are given in the question. using these details the answer to the given question can be easily reached.
Let us assume the common ratio to be x.
Then
x + 9x = 81
10x = 81
x = 81/10
= 8.1
A s we already know that the ratio of chaperones to students is 1:9
Then
The number of chaperones = 1 * 8.1
= 8.1
So 8.1 chaperones were there in total. I hope you have got the answer you were looking for.
