Answer:

Let the length of the first shelf = x

Length of second shelf = 2x + 18

Length of third shelf  = x - 12

Length of remaining shelf = x + 4

Since Robert has to use a board of 2.5 m , the sum of lengths of all these shelves should be 250 cm

<em>So, x + 2x + 18 + x - 12 + x + 4 = 250 </em>

<em>5x + 10 = 250</em>

<em>5x = 240</em>

<em>x = 48 cm</em>

Therefore, the length of the first shelf should be 48 cm

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>
