Answer:

Award Brainliest to this answer :)

Step-by-step explanation:

1 /  p + g = 150

g - 80 = p   =>  p - g = - 80

 

2 /  Adding the equations eliminates g and gives  2p = 70, p = 35

Back substituting to the 1st Equation;  35 + g = 150  =>  g = 115  

 

3 /  No, not if the stated conditions remain.

Express the ratio in the simplest form. 20 gallons to 0.75 gallons
expeople1 [14]

ANSWER

The ratio in the simplified form is

80:3

EXPLANATION

We want to express 20 gallons to 0.75 gallons as a ratio in its simplest form.

We obtain the ratio as follows:

20:0.75

This is the same as

20: \frac{3}{4}

We multiply each term in the ratio by 4 to obtain;

20 \times 4:0.75 \times 4

This gives us,

80:3

Restless Leg Syndrome and Fibromyalgia
Anna11 [10]

Answer:

The probability that a person with restless leg syndrome has fibromyalgia is 0.183.

Step-by-step explanation:

Denote the events as follows:

<em>F</em> = a person with fibromyalgia

<em>R</em> = 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)}\\\\=\frac{0.0066}{0.0066+0.0294}\\\\=0.183333\\\\\approx 0.183

Thus, the probability that a person with restless leg syndrome has fibromyalgia is 0.183.

In order to  see the probaability of this we need to do an easy calculation here:
If  X<span> is the price for the policy, then we proceed like this: 

</span>0.982x = 0.0275*<span>31,000
</span><span>
x = 0.0275*</span><span>31,000</span><span>/0.982
