Answer:
3/5
Step-by-step explanation:
7/15 + 2/15 = 9/15
both 9 nad 15 are divisible by 3
9/15 = 3/5
Answer:
556
Step-by-step explanation:
So, 378/189=2. So it will double two times. x2x2=x4. 139x4=556.
F(g(2)) = 3(x^3 + 1)^2 - 7 = 3(x^6 + 2x^3 + 1) - 7 = 3x^6 + 6x^3 + 3 - 7 = 3x^6 + 6x^3 - 4
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)
Answer:
+1
Step-by-step explanation:
Well (+) and (-) is equals basically to (-) when add ing them or multiplying them... so the difference is +1
