Answer:
c) finish-to-start; start-to-start
Explanation:
Project dependencies are the time relationships between a predecessor and a successor in project management. In other words, these dependencies describe which activity among the two needs to start earlier or later and when it needs to start or finish compared to the other one.
The most common type of dependency in all projects (no matter the nature or industry) is the finish-to-start one, where the activity A needs to be completed before activity B starts, e.g. base nail polish has to be put before the top coat gets put on the nails.
The second most common type of dependency is the<em> start-to-star</em>t one, where two activities need to start at the same time. This is common for activities where synchronization is paramount.
Answer:
Set.
Explanation:
Closure property in algebra asserts that 'when an operation(multiplication, addition) takes place among the members of a set, the result produced would surely be a member of that same set.' For example, if we add or multiply two real numbers(members of the same set), the result would be a real number for sure(a member of the same set). It implies that 'real numbers are closed under multiplication and addition.' While if I subtract two real numbers, I may or may not get a real number. Thus, the real numbers are closed under subtraction.
Answer:
Instructions are listed below
Explanation:
Giving the following information:
The high-low method involves taking the highest level of activity and the lowest level of activity and comparing the total costs at each level.
Mountain has recorded the following for the past nine months:
January:
Number of Cavities= 375
Total cost= $5,300
February:
Number of Cavities 500
TC= 5,850
March
Number of Cavities 350
TC= 5,200
April
Number of Cavities 600
TC=6,250
May
Number of Cavities 325
TC= 5,150
June
Number of Cavities 475
TC= 5,700
July
Number of Cavities 525
TC= 6,100
August
Number of Cavities 575
TC= 6,300
September
Number of Cavities 450
TC= 5,550
A) Variable cost= (Highest activity cost - lowest activity cost) / (Highest activity units - lowest activity units)
Variable cost= (6300 - 5150) / (600 - 325)= 4.18 per unit
Fixed cost= HACost - (variable cost per unit * HAUnits)= 6300 - (4.18*600)= 3792
Fixed cost= LACost - (variable cost per unit* LAUnits)= 5150 - (4.18*325)= 3792
B) Q= 400
Total cost= 3792 + 4.18*400= $5464
In statistics, reliability refers to how consistent a measurement scale is overall. Measurement scales with high reliability scores would be able to produce similar results when tested with groups of samples similar to the initial testing conditions.
Reliability scores are measured through reliability coefficient which spans from 0.0 to 1.0. What a reliability coefficient of 0.92 means is (B) 92% of the variance in scores is explained by real differences.
