Mathematics

Stells [14]3 years ago

Answer:

117 centimeters

Step-by-step explanation:

Since the longest pieces is 72 centimeters and it’s ratio is 8, that means the individual unit of the ratio is 9 (72/8=9). You can multiply each part of the ratio by 9

2x9=18

3x9=27

We already know the third part of the ratio is 72. Add all of it together to get the original length.

18+27+72=117 cm

Michael has interviewed for two jobs. He feels that he has a 50% chance of getting an offer on Job A and a 60% chance of getting
shutvik [7]

Using Venn probabilities, it is found that the probability that he receives an offer on at least one of the jobs is given by:

D. 0.80

<h3>What is a Venn probability?</h3>

In a Venn probability, two non-independent events are related with each other, as are their probabilities.

The "or probability" is given by:

P(A \cup B) = P(A) + P(B) - P(A \cap B)

In this problem, we have that:

  • 50% chance of getting an offer on Job A, hence P(A) = 0.5.
  • 60% chance of getting an offer on Job B, hence P(B) = 0.6.
  • 30% chance of getting an offer on both jobs, hence P(A \cap B) = 0.3.

Then, the probability of getting an offer on at least one job is:

P(A \cup B) = P(A) + P(B) - P(A \cap B) = 0.5 + 0.6 - 0.3 = 0.8

Hence option D is correct.
