Answer: 20 children
Step-by-step explanation:
<u>Given</u>
Year 4: 11 cannot swim
Year 5: 21 can swim
Year 6: 18 of 30 can swim
Total 96 children
Total 37 cannot swim
<u>First Step: find the number of people from year 5 who cannot swim</u>
- There are 30-18=12 people who cannot swim in year 6
- There are 11 who cannot swim in year 4
- Thus, we use the total number [37]-[year 4+year 6]=37-23=14 people who cannot swim in the year 5
<u>Second Step: find the number of children in year 5</u>
- There are 21 children who can swim
- There are 14 children who cannot swim
- 21+14=35 children
<u>Third Step: find the number of children in year 4 who can swim</u>
- There are 30 children in year 6
- There are 35 children in year 5
- There are 11 children in year 4 who cannot swim
- There are in total 96 children
- 96-30-35-11=20 children in year 4 who can swim

<u>Given </u>that the functions
and 
We need to determine the value of the function 
First, we shall determine the composition of the function 
<u>Function </u>
<u>:</u>
Let us determine the function 
Thus, we have;
![(g \circ f)(x)=g[f(x)]](https://tex.z-dn.net/?f=%28g%20%5Ccirc%20f%29%28x%29%3Dg%5Bf%28x%29%5D)
![=g[x+4]](https://tex.z-dn.net/?f=%3Dg%5Bx%2B4%5D)



Thus, the function is 
<u>Value of the function </u>
<u>:</u>
The value of the function can be determined by substituting x = -3 in the function 
Thus, we have;

Simplifying the terms, we get;



Thus, the value of the function
is 1.
Wow that is hardddddddddddddddddddddddddddddddddddddddd
The simplified ratio is 3:4
