Solve by taking the square root of both sides 3(x-1)^2-162=0

Natali5045456 [20]

We know that: 3(x-1)^2-162=0
or (x-1)²= 162:3
and (x-1)²= 54
we take the square root of both sides
* x-1=√54= 3√6 or x=1+3√6
* x-1= -√54= -3√6 or x=1-3√6
This equation has 2 solutions

Restless Leg Syndrome and Fibromyalgia

mixas84 [53]

Answer:

The probability that a person with restless leg syndrome has fibromyalgia is 0.1833.

Step-by-step explanation:

Denote the events as follows:

F = a person with fibromyalgia

R = a person having restless leg syndrome

The information provided is as follows:

P (R | F) = 0.33

P (R | F') = 0.03

P (F) = 0.02

Consider the tree diagram attached below.

Compute the probability that a person with restless leg syndrome has fibromyalgia as follows:

$P(F|R)=\frac{P(R|F)P(F)}{P(R|F)P(F)+P(R|F')P(F')}\\\\=\frac{(0.33\times 0.02)}{(0.33\times 0.02)+(0.03\times 0.98)}\\\\=0.183333\\\\\approx 0.1833$

Thus, the probability that a person with restless leg syndrome has fibromyalgia is 0.1833.
