I believe it's B because we don't know how big the jar is and it's asking for. a statistical question.
Well if I did the math correctly it should be B) <span>9√5</span>
Answer:
x=1/3
Step-by-step explanation:
A function f is given as
in the interval [0,1]
This function f being an algebraic polynomial is continuous in the interval [0,1] and also f is differntiable in the open interval (0,1)
Hence mean value theorem applies for f in the given interval

The value

Find derivative for f

Equate this to -5 to check mean value theorem

We find that 1/3 lies inside the interval (0,1)
40/100= 56/x
40x=100(56)
40x=5600
Divide both sides by 40 to get x alone.
X=140
