A project consists of 8 activities. The activity completion times and the precedence relationships are as follows: Activity. Completion time Days. immediate predecessor activities.

A. 5 -
B. 7 -
C. 6 -
D. 3 A
E. 4 B, C
F. 2 C
G. 6 A, D
H. 5 E, F

1. Draw the network diagram using AON model notations:

2. What is the critical path?

3. Calculate: Early Start, Early finish, Late start, Late finish, slack, critical path.

4. What is the minimum time to complete the projects?

1. If activity E is delayed by 3 days how is the project completion time affected? Why is this the case?

2. If activity F is delayed by 3 days how is the project completion time affected? Why is this the case? Will the critical path change, why or why not?

3. If you want to shorten (crash) the overall time of this project, how do you pick which activity to shorten? What information, if any, do you need?

4. Once you shorten (crash) an activity, do you need to redo the AON, yes or no? Why or why not?

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.

step-by-step explanation:

answer: 323 is how many she has ☃☃⛄❄

step-by-step explanation:

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
