Answer: 0.0475
Step-by-step explanation:
Let x = random variable that represents the number of a particular type of bacteria in samples of 1 milliliter (ml) of drinking water, such that X is normally distributed.
Given:
The probability that a given 1-ml will contain more than 100 bacteria will be:
∴The probability that a given 1-ml will contain more than 100 bacteria
0.0475.
B) 7x - 1
<h3>Step-by-step explanation:</h3>In this question, you're going to solve by adding both f(x) and g(x) together.
You're finding (f+g)(x), meaning that you will be adding both of the equations to get your answer.
What (f+g)(x) looks like:
(5x - 2 + 2x + 1)(x)
What you would do is solve to get your answer. You're going to be combining like-terms and adding.
When you're done solving, you should get 7x - 1
This means that B) 7x - 1 would be the correct answer.
