Answer:
Yes
Step-by-step explanation:
They add up to 90 degrees.
In this you could say 2.5L and 3.5L for total 6L. minus the 5L drunk and get about a liter left. in actuality:
x = 2.45 + 3.65 - 4.85 = 1.25
I would say that the estimation was reasonable.
in probability, it is equally as likely that a decimal lies between x and x.5 as it is for it to lie between x.5 and x+1. therefore when given a few numbers the rounding effect would likely round overall the same amount of points down as up. this would make it likely that the estimation would have on my an error within the amount rounded to. as you can see I rounded to 0.5 and the answer was half that
I’d say option 4
However, one may think option 3 might be possible as well. But that it is not interacting, it’s affecting.
So I’d stick with option 4.
Good luck!
Can’t see the numbers from the picture but the zeros are where the parabola crosses the x-axis in 2 places, the axis of symmetry is the highest or lowest points and it is maximum or minimum depending on what way it goes.
Most likely it’s x=7 unless there are other options you didn’t show
