Three recent college graduates have formed a partnership and have opened an advertising firm. Their first project consists of ac

tivities listed in the following table
Activity | Immediate Predecessor | Optimistic | Most Likely Pessimistic
A — 5 6 7
B — 8 8 11
C A 6 8 11
D — 9 12 15
E C 5 6 9
F D 5 6 7
G F 2 3 7
H B 4 4 5
I H 5 7 8
End E, G, I
b. Suppose it is now the end of the seventh day and that activities A and B have been completed while activity D is 50 percent completed. Time estimates for the completion of activity D are 5, 6, and 7. Activities C and H are ready to begin. Determine the probability of finishing the project by day 24 and the probability of finishing by day 21. (Round your intermediate calculations to 3 decimal places and final answers to 4 decimal places.)

The precedence diagram for the problem above is attached. See the definition of a precedence diagram and the probability calculations below.

<h3>What is a precedence Diagram?</h3>

A precedence diagram is an optical or graphical representation tool that displays a project's activities.

<h3>What is the probability of finishing the project by the 24th day or less?</h3>

Recall that:

z = (Specified Time - Path's mean)/Path's Standard Deviation.

Hence for z₂₁

(21 − 20.5)/1.118   = 0.447 ≈ 0.45.

Hence the probability is:   P(Z<0.45) =0.6736

(21 − 21.5)/1.344 = −0.3721 ≈ −0.37

Hence the probability is:  P(Z<-.37) = 0.3557

(21 − 19.5)/.726 = 2.066 ≈ 2.07

Hence the probability is: P(Z<2.07) = 0.9808

Following through on the above, the project will be finished in less than 21 days is given as:

P = 0.23499920921

P ≈ 0.2350

The yield to maturity on a bond is:
Arada [10]

Answer:

The correct answer is I, II and III.

Explanation:

The return that an investor earns with a bond can be calculated in different ways. The price of the bonds fluctuates with the change in interest rates, but once the investor buys a bond, the return is fixed. The yield to maturity is a way of providing the investor with the most accurate representation of the return he will receive for the holding of said bond.

Types of bond yield

Based on the current price, a bond shows three different types of maturity. The yield of the coupon is the interest rate paid by the bond at face value. A US $ 10,000 bond with a 6 percent interest coupon pays US $ 300 interest every 6 months. The current return is the coupon rate divided by the bonus price. If the bond with a nominal value of US $ 10,000 and a 6 percent coupon rate can be purchased for US $ 9,600, its current yield is 6.25 percent. The yield at maturity is the internal rate of return of the bond based on the time remaining for the bond's maturity.

Expiration Yield

The calculation of the yield at maturity amortizes the value of the premium or the discount (bonds over and under the pair) in the price of the bond throughout the life of the bond. For example, if the bond that pays 6 percent of the aforementioned coupon rate expires in 10 years, and is priced at US $ 9,600, the yield at maturity is 6,558 percent. If two bonds, one on the pair and one under the pair, have the same yield at maturity, any of them represents the same level of return for the investor. The yield at maturity is what the investor will receive if the bond is purchased at the current market price and held until maturity.

Last year a company spent $11 million on Internet advertising. If that amount increases by 17 percent this year, how much will t
never [62]

If a company spent that much on internet advertising and increased it by 17%, the new amount spent would be $12.87 million.

<h3>How much did the company spend on advertising?</h3>

The amount spent can be calculated as:

= Amount x (  1 + increase in advertising)

Solving gives:

= 11 million x (  1 + 17%)

= 11 x 1.17

= $12.87 million

shutvik [7]

Answer:

Micro environment                                              

Explanation:

The institution's micro-environment comprises of those components that are manageable. Generally the micro-environment doesn't really impact all businesses in a sector in same manner, as the scale, efficiency, competence and approaches are different.

For instance, the suppliers of raw materials are giving big corporations more compromises. We might not offer small businesses the same concessions though. Thus, from the above we can conclude that the correct answer is micro-environment.
