Free_Kalibri [3773]

Answer:

  • As explained below, with the individual’s score in the 0.03125 fraction of top candidates, they can anticipate securing a position.

Explanation:

Utilizing Chebyshev’s Theorem is key.

This theorem is valid for any dataset, irrespective of its shape.

Chebyshev's Theorem states that at least 1−1/k² of the data falls within k standard deviations from the mean.

For this data set, the specifics are:

  • mean: 60
  • standard deviation: 6
  • score: 84

The number of standard deviations that 84 is from the mean can be calculated as:

  • k = (score - mean) / standard deviation
  • k = (84 - 60) / 6 = 24 / 6 = 4

Hence, the individual’s score is 4 standard deviations above the mean.

How significant is this?

According to Chebyshev’s Theorem, at least 1−1/k² of the data is within k standard deviations from the mean. Setting k = 4 gives us:

  • 1 - 1/4² = 1 - 1/16 = 0.9375

  • This implies that half of 1 - 0.9375 exceed k = 4: 0.03125

  • Consequently, 1 - 0.03125 is below k = 4: 0.96875

With 70 job openings and 1,000 applicants, the ratio is 70/1,000 = 0.07, indicating the company seeks the top 0.07 of applicants.

Given the individual scores in the top 0.03125 of applicants, they can expect to obtain a job.

soldi70 [3635]

Answer:

$250,000

Explanation:

The down payment is calculated as the total house price minus the mortgage amount: $550,000 - $300,000 = $250,000

There seems to be an inconsistency in this question, as saving $250,000 over 5 years suggests an annual savings of about $50,000. If one could save this amount yearly, then they should be able to afford a larger mortgage. The typical 30-year mortgage carries an average APR of slightly above 4% (usually between 4.04% - 4.16%). This would result in a monthly payment of roughly $1,151 including insurance.

Thus, consider either approaching a different bank (if your income truly supports this) or looking for a less expensive home.
