In a school, 600 students passed in Mathematics, 450 passed in Science and 300 in both subjects. i) How many students are there in the school?
ii) How many students were passed in Science only?
iii) How many students were passed in Mathematics only?
iv) Represent the above information in a Venn-diagram.
Help me.​

1. 1350 kids

2. 450

3. 600

Step-by-step explanation

I can help with the venn diagram, sorry.

but heres the explanation

600 plus 450= 1050+300=1350

Ps, I REALLY HOPE THIS HELPS!!! <3

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
