The equivalent expression of a + 5 is -(-a - 5)
<h3>How to rewrite the expression?</h3>
The expression is given as:
a + 5
Multiply by 1
1 * (a + 5)
Express 1 as -1 * -1
-1 * -1 * (a + 5)
Open the bracket
-1 * (-a - 5)
This gives
-(-a - 5)
Hence, the equivalent expression of a + 5 is -(-a - 5)

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

Thus, the probability that a person with restless leg syndrome has fibromyalgia is 0.1833.
Answer:
Step-by-step explanation:
From the problem statement, we can setup the following equation:

where
is the number of people that would show up to the zoo on a given day.
Dividing both sides by 7 will give us the answer:

2 (d(h+w) + h w) is the surface area
