Answer:
Explanation:
An expression was assumed for E(V) = av^2 + bv + c
each values for substituted for corresponding values of the velocity and a three unknown equation was formed, which was solved simultaneously to get the three unknowns (a, b and c).
The unknowns was substiutted back ito the original equation.
Problem Solvers
Explanation:
Engineers find problems in the world, and then they find solutions for them.
Answer:
Estimated number of indigenous faults remaining undetected is 6
Explanation:
The maximum likelihood estimate of indigenous faults is given by,
here,
= the number of unseeded faults = 6
= number of seeded faults = 30
= number of seeded faults found = 15
So NF will be calculated as,
And the estimate of faults remaining is 
= 12 - 6 = 6
The figure c measures 38• so it would be an angle of 48 and a degree of 67
Answer: CARDINALITY RATIO AND PARTICIPATION
ADVANTAGE
CARDINALITY RATIO
(THEY ARE USED TO SIMPLIFY DESIGNS)
DISADVANTAGE OF CARDINALITY RATIO IS THAT
(YOU CAN NOT SPECIFY A GIVEN NUMBER TO BE MAXIMUM)
ADVANTAGE OF PARTICIPATION CONSTRAINT IS THAT
(IT SHOWS WETHER THE EXISTENCE OF AN ENTITY IS DEPENDENT ON ITS RELATIONSHIPS WITH ANOTHER ENTITY)
DISADVANTAGE OF PARTICIPATION CONSTRAINT
(IT IS A COSTLY AFFAIR USING BOTH MODELS TO EXPRESEE RELATIONSHIPS).
Explanation:CARDINALITY RATIO specifies that maximum number of relationships an entity can engage itself in.
Participation constraint is a constraint that
Specifies whether the existence of an entity depends on its Relationships to another entity, it specifies the the minimum number of relationship instances that an entity can participate in
It is also minimum cardinality constraint,it has two types named as Total participation and partial participation.
