Answer:
this is a cost minimization problem, but it is missing some numbers, so I looked for similar questions (see attached PDF):
minimization equation = 20x₁ + 22x₂ + 18x₃ (costs per ton)
where:
x₁ = mine I
x₂ = mine II
x₃ = mine III
the constraints are:
4x₁ + 6x₂ + x₃ ≥ 54 (high grade ore)
4x₁ + 4x₂ + 6x₃ ≥ 65 (low grade ore)
x₁, x₂, x₃ ≤ 7 (only 7 days per week)
using solver, the optimal solution is
2x₁, 7x₂, and 5x₃
a. The number of days Mine I should operate = <u>2 days
</u>
b. The number of days Mine Il should operate = <u>7 days
</u>
c. The number of days Mine III should operate = <u>5 days
</u>
d. The total cost of the operation for next week = <u>$284,000</u>
Answer: Option B
Explanation: In simple words, Information management refers to the governance of the information assets of the organisation.
Under this, the managers collects the information,that is useful to various stakeholders, from several different resources and then distributes it those stakeholders.
In the given case, Kristin is also managing the information that is useful to the organisation.
Hence the correct option is B.

Answer:
The answer is D) Nora has a positive tracking signal.

Answer:
The portfolio return is 12.6% and the portfolio SD is 15.4%. Thus, option a is the correct answer.
Explanation:
The expected return of a portfolio is the weighted average of the individual stock returns that form up the portfolio. Thus, the expected return for a two stock portfolio is,
Return of Portfolio = wA * rA + wB * rB
Where,
- w represents the weight of each stock in the portfolio
- r represents the return of each stock
Portfolio return = 0.7 * 0.15 + 0.3 * 0.07 = 0.126 or 12.6%
The standard deviation of a two stock portfolio containing one risky and one risk free asset is the weight of risky asset in the portfolio multiplied by the standard deviation of the risky asset. The risk free asset has zero standard deviation.
Standard deviation of such a portfolio is,
Portfolio SD = w of risky asset * SD of risky asset
Portfolio SD = 0.7 * 0.22
Portfolio SD = 0.154 or 15.4%
