There are quite a few stages to this problem, so let's work through each piece of information one by one.
We know that the total number of children is 120, and 60% are Year 4s. Finding 60% straight away can be tricky so we should find 10% first.
To find 10%, we just divide 120 by 10, which gives us 12. Now we know 12 = 10%, we need to multiply both numbers by 6 in order to find 60%.
10% x 6 = 60%
12 x 6 = 72
So 72 students are in Year 4.
We are told 1/4 are boys. So we need to find one quarter of the total number of students in Year 4. We do this by dividing 72 by 4.
72 / 4 = 18
So we have 72 Year 4s, 18 of which are boys. However we want to find the girls. Therefore we take the total and subtract the number of boys:
72-18 = 54
There are 54 Year 4 girls on the tripsee more
First we rearrange the equation
y + 4x = 7 to y = −4x + 7
So we can see that the gradient of this equation is −4.
Since the line we are looking for is parallel, it must have the same gradient, −4.
So now we know we have a line for equation:
y = −4x + m
which passes through the point ( 2, −3).
We can set the values into the equation to find m:
−3 = −4 x 2 + m
−3 = −8 + m
Now we add 8 to both sides
5 = m
So we see that the value of m is 5 and the equation we are looking for is:
y = −4x + 5see more
In answering this question, a few things must be taken into consideration. FIrstly, the question clearly asks for the advantages of being a sole trader. This means that any time wasted in explaining a disadvantage of this will gain no marks. The marks allocated to the question give an idea of how many advantages you may need to put across. If this question was for 8 marks, you would probably need to explain in detail about 4 advantages. An evaluation point may help at the end of your response.see more
