Can you please explain how you got the answer? Also plz tell me what the closed and open circle mean again..
ale4655 [162]

Answer: A

Step-by-step explanation:

  • Open circle means that x does not equal that number. For example, the open circle on C is on 8, so that shows x is not equal to 8.
  • Closed circle means that x does equal that number. For example on A, there is a closed circle on 8, so x could equal 8.

First, we need to solve the equation.

  1. Subtract 200 frim 1200 -> 125x ≥ 1000.
  2. Divide 125 from 1000 to isolate the x -> x ≥ 8

So, that means x is bigger than or equal to 8.

Let p and q be statements. Identify the truth table for q → p.
Serjik [45]

Answer:

T F T T.

Step-by-step explanation:

Let p and q be two statement

When the value of p is true and the value of q is true then the value of q\implies p is true.

When the value of p is true and the value of q is  false then the value of q\implies p is true.

When the value p is false and the value of q is true then the value of q\implies p is false.

When the value of p  is false and the value of q is false then the value of q\implies p is true.

Hence, the value of q\implies p is false when q is true and p is false.

4                      13,600                     25,200

<h3>What is the IRR for each of these projects?</h3>

using an excel spreadsheet and the IRR function:

Project A's IRR = 28.3%

Project B's IRR = 25.7%

(b) If you apply the IRR decision rule, which project should the company accept?

Project A (its IRR is higher)

Requirement 2:

(a) Assume the required return is 14 percent. What is the NPV for each of these projects?

using an excel spreadsheet and the NPV function:

Project A's NPV = $14,921.37

Project B's NPV = $15,156.64

(b) Which project will you choose if you apply the NPV decision rule?

Project B (its NPV is higher)

Requirement 3:

(a) Over what range of discount rates would you choose Project A?

higher than 14.85%

(b) Over what range of discount rates would you choose Project B?

lower than 14.85%

(c) At what discount rate would you be indifferent between these two projects?
