Sounds like you're asked to find

such that

In other words, find

that satisfies

We can factorize this as

In order that

describes a probability distribution, require that

for all

, which means we can ignore the possibility of

.
Let

.


Multiply both sides by

.

We want to find

that removes the quartic and quadratic terms from the equation, i.e.

so the cubic above transforms to

Substitute

and we get

![\implies y=\sqrt[3]{\dfrac{9+\sqrt{93}}{18}}](https://tex.z-dn.net/?f=%5Cimplies%20y%3D%5Csqrt%5B3%5D%7B%5Cdfrac%7B9%2B%5Csqrt%7B93%7D%7D%7B18%7D%7D)
In each quantity of 87 cg, 1 of them is active ingredient. In the quantity of interest,
... (1/87)·522 cg = 6 cg . . . is active ingredient
The remainder of that quantity, 516 cg, is inactive ingredient.
Answer:
Yes
Step-by-step explanation:
The line is pointing up therefore the slope will be positive
