Private universities claim to offer a higher quality education compared to public universities as justification for their more e

xpensive tuition rates. The implication is that better education in the classroom leads to better employees after graduation. As a HR specialist in charge of selecting the best possible future employees from a pool of applicants, you propose giving preference to applicants with degrees from private universities. Hoping to control for the influence of academic performance on on-the-job performance, you randomly select 25 pairs of employees based on their cumulative GPA, one with a degree from a private university and another with a degree from a public university, and record their last performance evaluation score in an Excel file. The data appears as follows:
GPA Private University Alumni Public University Alumni
4.0 85 89
3.9 82 78
3.8 75 77
3.7 91 72

When the initial input is 8 in what order should the machines be arranged so that the final output is 2?
Dima020 [189]

When the initial input is equal to 15 and the final output is -6, the machines should be stacked in this order:

  1. Fourth machine (y₄ = -2x + 34)
  2. Second machine (y₂ = (x - 2)²)
  3. First machine (y₁ = -|3x|)
  4. Third machine (y₃ = -x/3 - 10)

When the initial input is equal to 8 and the final output is 2, the machines should be stacked in this order:

  1. First machine (y₁ = -|3x|)
  2. Third machine (y₃ = -x/3 - 10)
  3. Second machine (y₂ = (x - 2)²)
  4. Fourth machine (y₄ = -2x + 34)

<h3>How to determine the arrangement?</h3>

From the information provided, we know that the initial input is equal to 15 and the final output is -6. Thus, we would solve the puzzle as follows:

For the fourth machine, we have;

y₄ = -2x + 34

y₄ = -2(15) + 34

y₄ = -30 + 34

y₄ = 4.

Therefore, the output is equal to 4.

For the second machine, we have:

y₂ = (x - 2)²

y₂ = (4 - 2)²

y₂ = 2²

y₂ = 4

Therefore, the output is equal to 4.

For the first machine, we have:

y₁ = -|3x|

y₁ = -|3 × 4|

y₁ = -12.

Therefore, the output is equal to -12.

For the third machine, we have:

y₃ = -x/3 - 10

y₃ = -(-12)/3 - 10

y₃ = 12/3 -10

y₃ = 4 - 10

y₃ = -6

Therefore, the output is equal to -6.

In conclusion, we can logically deduce that the machines should be stacked in this order:

  1. Fourth machine (y₄ = -2x + 34)
  2. Second machine (y₂ = (x - 2)²)
  3. First machine (y₁ = -|3x|)
  4. Third machine (y₃ = -x/3 - 10)

<h3>Part 2.</h3>

When the initial input is equal to 8 and the final output is 2. Thus, we would solve the puzzle as follows:

y₁ = -|3x|

y₁ = -|3 × 8|

y₁ = -24.

For the third machine, we have:

y₃ = -x/3 - 10

y₃ = -(-24)/3 - 10

y₃ = 24/3 -10

y₃ = 8 - 10

y₃ = -2.

For the second machine, we have:

y₂ = (x - 2)²

y₂ = (-2 - 2)²

y₂ = 4²

y₂ = 16

For the fourth machine, we have;

y₄ = -2x + 34

y₄ = -2(16) + 34

y₄ = -32 + 34

y₄ = 2.

When the initial input is equal to 8 and the final output is 2, the machines should be stacked in this order:

  1. First machine (y₁ = -|3x|)
  2. Third machine (y₃ = -x/3 - 10)
  3. Second machine (y₂ = (x - 2)²)
  4. Fourth machine (y₄ = -2x + 34)

Complete Question:

1. In what order should you stack the machines so that when 15 is dropped into the first machine, and all four machines have had their effect, the last machine’s output is -6?

2. When the initial input is 8 in what order should the machines be arranged so that the final output is 2?

natali 33 [55]

Answer:

(5, -1)

Step-by-step explanation:

Equation 1:   3x + y = 14

Equation 2:   2x - 2y = 12

Rewrite equation 1 to make y the subject:

⇒ y = 14 - 3x

Substitute this into equation 2 and solve for x:

⇒ 2x - 2(14 - 3x) = 12

⇒ 2x - 28 + 6x = 12

⇒ 8x - 28 = 12

⇒ 8x = 40

⇒ x = 5

Substitute found value for x into either equation and solve for y:

using equation 1:

⇒ 3(5) + y = 14

⇒ 15 + y = 14

⇒ y = -1

Therefore, the solution to the system is (5, -1)
