1. U( x ₁ , x ₂ ) = min { x ₁, x ₂ }

If the price of good 1 is $8/unit, the price of good 2 is $2/unit, and income is $51...

What is this person's optimal consumption level for good 2?

2. U( x ₁, x ₂ ) = min { x₁ /2 , x ₂}

If the price of good 1 is $4/unit, the price of good 2 is $8/unit, and income is $93...

What is this person's optimal consumption level for good 2?

1.Evaluate (1 + a) / (1 + a^2)

2. A generator having a solidly grounded neutral and rated 50 MVA, 30 kV has a positive, negative and zero sequence reactances of 20, 20 and 5 percent respectively. What reactance must be place in the generator neutral to limit the fault current or a bolted single line to ground fault to that for a bolted three phase fault?

3. The positive, negative and zero sequence reactances of a 15 MVA, 11 kV three-phase wyeconnected generator are 11%, 8% and 3% respectively. The neutral of the generator is grounded and is excited to the rated voltage on open circuit. A line to ground fault occurs on phase a of the generator. Calculate the fault current.

Question 1:

Which is best practice?

• A. Contrasts of interest are determined by research questions and should be explicitly stated at the planning stage of an experiment.
• B. Contrasts of interest are best determined during the exploratory data analysis stage.
• C. The contrasts one should investigate are determined by the observed difference between treatment means; bigger observed differences are more interesting

Question 2

Which of the following is a contrast and orthogonal to

?1=4?1−(?2+?3+?4+?5)

• A.

  ?2=?1−?3

• B.

  ?3=4?1+(?2+?3+?4+?5)

• C.

  ?4=?2−?3

Question 3

A contrast is a comparison of means.

Question 4:

Which of the following qualifies as a contrast?

• A.

  ?1=0.5?1+0.5?2

• B.

  ?2=??1–0.5(?2+?3)

• C.

  ?3=?1+?2+?3

• D.

  ?4=13(?1+?2+?3)

Show all details. Thanks
