The answer would be 1/3 of the population is children. All you need to do to solve this problem is divide the portion of the population (in this case, children) by the total of the population. Therefore, you have 1342/4026 which reduces to 1/3. If you would like to represent this as a percent, it would be approximately 33.33%
Answer:
I'm sorry but there is no diagram
The graph of the journey is shown in the speed-time graph below
At the time = 3 minutes, Peter would have achieved the speed V.
The distance he travelled is the area under the line as shown in the graph
We first need to find the V by using the area of a rectangle formula
so V=220
the gradient the f slope then given as

Answer:
Step-by-step explanation:
First, subtract 7 from each side.
Now, add in a blank on each side so you can write in your new term that will complete the square. We'll call that term 's' for now.
The next step is to take half of the b term, and then square that. In this case, half of '' is . If we square that we get . So that is the term we will put in for .
Simplify:
If you look at the right side of the equation, we can factor. That's because we <u>completed the square</u>. We can use the 'guess and check' method to factor. Remember, this is where we use 2 sets of parentheses and fill in the blanks.
If we were to FOIL the right side we would end up with .
Since we have 2 '(x-1)' terms next to each other, we can simplify to:
Now, all we need to do is add 6 to both sides and we have the vertex form.
I hope this helps!
