Consider the following table of activities A through E in which A is the start node and E is the stop node. Assume the project starts on Monday, May 4, 2020 and no work is done on weekends (Saturday and Sunday). All activities require the same resource. Assume no working-day holidays during the months of May and June—no Memorial Day holiday, for example.

Activity	Duration (days)	Predecessor
A	5	--
B	5	A
C	10	A
D	4	A
E	5	B, C, D

On a piece of scratch paper, draw the early-start Gantt Chart associated with this table. Assume the project is resource-constrained but not time-constrained. Assume only one resource is available and that resource can only do one activity at a time. Given that the Month of May has 31 days, what would be the completion date for the project?

Monday, June 8, 2020
Wednesday, June 10, 2020
Friday, June 5, 2020
Thursday, June 11, 2020
Thursday, June 4, 2020

Expert Solution

ANSWER: Thursday, June 11, 2020

------------------------------------------------

Explanation:

Gantt chart based on Early Start and Finish times is following:

In the above Gantt chart, we see that there is resource over-load in periods 6 to 10

Resource over-load is because activities B,C,D are scheduled to start on the same day and occur concurrently.

We need to schedule them sequentially

Resulting Gantt chart is following:

Total number of working days to complete the project = 29 working days

Considering 5 working days per week and starting date of May 4, 2020

Completion date is:

Thursday, June 11, 2020

Consider an unweighted, undirected graph G = <V, E>. The neighbourhood of a node v ∈ V in the graph is the set of all nodes that are adjacent (or directly connected) to v. Subsequently, we can define the neighbourhood degree of the node v as the sum of the degrees of all its neighbours (those nodes that are directly connects to v). (a) Design an algorithm that returns a list containing the neighbourhood degree for each node v ∈...

For each E coli genotype and condition in the following table, choose which sets of functional proteins will or will not be produced. All grown in media with no/low glucose. IS indicates a super-repressor (it can’t bind to lactose/inducers). OC indicates a constitutive operon (no repressor can bind to this region of DNA). I- ; Z- ; Y-each indicate an allele that does not produce a functional protein. P- indicates a mutation in the promoter region such that RNA polymerase...
