Answer: Option 1.
<u>Explanation:</u>
Certain sampling and testing are done by the scientists and the doctors about the diseases on the people so that the doctors can come out with the medicinal treatment or some other kind of cure for that particular kind of disease.
In the case that has been discussed in the question above, the people that are suffering from this disease are four people out of hundred people who were tested for the disease.
Answer:
x = -4
Step-by-step explanation:
1/2x - 20 - x = 6x -3 -2x +1
-1/2x -20 = 4x -2
-1/2x -4x = -2 +20
-9/2x = 18
9/2x = -18
9x = -36
x = -4

hope this helps :)
The one u originally clicked (in yellow) is correct. all sides match perfectly with the figure.
360.
A general rule of thumb when dealing with questions like these is using the following equation:
(number of numbers) x (mean) = sum of numbers
Proof/Example: 7, 10, 13
There are 3 numbers here and the mean is 10. Multiply them together and you will get 30, just as you will get 30 from adding them together.
In this case, there are 4 numbers and the mean is 90, so 4 x 90 = 360.
Step-by-step explanation:
<u>Finding Vertex</u>
Given

The vertex of an up-down facing parabola of the form

The Parabola params are:







∵ 





Therefore the parabola vertex is:





<u>Finding symmetry</u>
For a parabola in standard form 
the axis of symmetry is the vertical line that goes through the vertex 




Therefore,
