The example I would be using is the level of a see-saw and take a point 1 /x of the way amid the middle and the left end. If you change the point vertically by f feet, the far right finish transfers vertically by f×−x feet. If you push down, f would be negative then you are multiplying two negative numbers for a positive result, this means that the other end moves up.

Suppose that start-up companies in the area of biotechnology have probability 0.2 of becoming profitable, and that those in the
Aleks04 [339]

Answer:

<u>The probability that both companies become profitable is 0.03 or 3%.</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Probability of biotechnology start-up company of becoming profitable = 0.2

Probability of information technology start-up company of becoming profitable = 0.15

2. Assume the companies function independently What is the probability that both companies become profitable?

We will answer this question, assuming these are independent events, this way:

Probability that both companies become profitable = Probability of biotechnology start-up company of becoming profitable * Probability of information technology start-up company of becoming profitable

Replacing with the values given, we have:

Probability that both companies become profitable = 0.2 * 0.15 = 0.03

<u>The probability that both companies become profitable is 0.03 or 3%.</u>

Do the rays BA and AB define the same ray? In complete sentences, explain why the two rays are the same or why the two rays are
Deffense [45]
Rays are named according to their endpoints, the first one named is the "starting" endpoint, the second one is the one that will continue on into infinity.  Therefore, ray BA has a terminal endpoint at B and goes through point A into infinity.  Ray AB has a terminal endpoint at A and goes through point B into infinity.  Definitely NOT the same ray.
