Answer:
7 / 20
Step-by-step explanation:
To find the probability, we will find the total number of guinea pigs infected.
<h2>(50 + 125) / 500 =</h2><h2>= 175 / 500</h2><h2>= 7 / 20.</h2>
The probability of the guinea pigs being affected is 175 / 500 = 7 / 20.
The domain is all the x-values you can use with this function. When dealing with a function like this, you need to ask yourself, what would make the bottom equal to 0? Whatever those numbers are, you do NOT want them in your domain.
A fundamental rule is that you cannot divide by 0 or have 0 as a denominator.
So, you solve x^2+6x=0 to find that x=0 or x=-6 would make the denominator 0.
The domain is everything BUT those two values, because they essentially break your function.
