The median is 12.
There are 23 dots.
11 on 1 side. 12. 11 on the other
11+11+1=23.
Vertex: (-2,-3)
axis of symmetry: x=-2
min: (-2,-3)
max: no max because it is a parabola tht opens up
Range: y > or equal to -3

Let's plug the given values and find value of y ~










or, you can further simplify it to ;

Answer:
- 40 ml of water must be added.
Step-by-step explanation:
Initial volume of mixture is 100 ml with oil to water ratio of 1 : 4.
First, let's find the volume of each component.
If the oil is x then water is 4x according to ratio and their sum is 100 ml:
- x + 4x = 100
- 5x = 100
- x = 20
So, we have 20 ml of oil and 80 ml of water.
Now, let's added volume of oil be y. Then we have the ratio:
- (20 + y)/80 = 1/2
- 20 + y = 40
- y = 20
So, we have 40 ml of oil and 80 ml of water.
Lastly, let's added water be z. Then we have the ratio:
- 40/(80 + z) = 1/3
- 80 + z = 120
- z = 40
We must add 40 ml of water.
