Express each of these system specifications using predicates, quantifiers, and logical connectives, if necessary.
a. At least one console must be accessible during every fault condition.
b. The e-mail address of every user can be retrieved whenever the archive contains at least one message sent by every user on the system.
c. For every security breach there is at least one mecha- nism that can detect that breach if and only if there is a process that has not been compromised.
d. There are at least two paths connecting every two dis- tinct endpoints on the network.
e. No one knows the password of every user on the sys- tem except for the system administrator, who knows all passwords.
Answers
The system specification with predicates, quantifiers, and logical connectives are:
a. ∃C(x) ∀F(y) such that if F(y) is true, C(x) is true.
b. ∀U(x) (∃M(y) if ∀U(z), ∃M(w) is true, then E(x) is true).
c. ∀B(x) (∃D(y) D(y) can detect B(x) ↔ (∃P(z) ¬P(z) is true)).
d. ∀E(x, y) (∃P(z, w) and ∃P(u, v) such that P(z, w) and P(u, v) connect
E(x, y)).
e. ∀U(x) (¬P(x) is true, except for the system administrator who knows all passwords: ∀U(y) P(y) if y is the system administrator).
We have,
a.
Let C(x) be the predicate "x is a console" and F(x) be the predicate "x is a fault condition".
The specification can be expressed as:
∀F(x) ∃C(y) such that if F(x) is true, C(y) is true.
b.
Let U(x) be the predicate "x is a user" and M(x) be the predicate "x is a message".
The specification can be expressed as:
∀U(x) ∃E(y) such that if ∀U(x), ∃M(z) is true, E(y) is true.
c.
Let B(x) be the predicate "x is a security breach", D(x) be the predicate "x is a detection mechanism", and P(x) be the predicate "x is a compromised process".
The specification can be expressed as:
∀B(x) ∃D(y) such that D(y) can detect B(x) if and only if ∃P(z) such that ¬P(z) is true.
d.
Let E(x, y) be the predicate "x and y are distinct endpoints" and P(x, y) be the predicate "x and y are connected by a path".
The specification can be expressed as:
∀E(x, y) ∃P(z, w) and ∃P(u, v) such that P(z, w) and P(u, v) connect E(x, y).
e.
Let U(x) be the predicate "x is a user" and P(x) be the predicate "x knows the password".
The specification can be expressed as:
∀U(x) ¬P(x) is true, except for the system administrator who knows all passwords, which can be expressed as:
∀U(x) (x is the system administrator → P(x)).
Thus,
The system specification with predicates, quantifiers, and logical connectives are:
a. ∃C(x) ∀F(y) such that if F(y) is true, C(x) is true.
b. ∀U(x) (∃M(y) if ∀U(z), ∃M(w) is true, then E(x) is true).
c. ∀B(x) (∃D(y) D(y) can detect B(x) ↔ (∃P(z) ¬P(z) is true)).
d. ∀E(x, y) (∃P(z, w) and ∃P(u, v) such that P(z, w) and P(u, v) connect
E(x, y)).
e. ∀U(x) (¬P(x) is true, except for the system administrator who knows all passwords: ∀U(y) P(y) if y is the system administrator).

If the area of a shape is 50 square feet and the width is 10 feet, what is the lentgth
Answers
Answer:
5 feet
Step-by-step explanation:
To find the length of the shape, we can divide the area to the width.
Formula for area is [ a = lw ].
Since we are solving for length, the formula will be [ l = a/w ]
l = 50/10
l = 5

A store buys 8 sweaters for $72 and sells them for $288. How many profit does the store make per sweater?
Answers
Answer:
$27 per sweater
Step-by-step explanation:
To solve this, all we need to do is subtract the profit made by the amount the store bought the sweaters for:
288 - 72 = 216
Now, we can divide this number by 8 to find how much profit the store made per sweater:
216 / 8 = 27
So, the store made a profit of $27 per sweater.
Hope this helps :)

elana went to the store where you can scoop your own popcorn and buy as much as you want. She bought 10 ounces spicy popcorn for $2.50
how much dose popcorn cost per ounce
Answers
Answer:
each ouce is worth 25 cents
solution
in order to solve this you need to create proportions so
10 ounces
per $2.50
well you want this to be a unit rate so you would have
10 ounces = 1 ounce
2.50 x
to get to the unit rate, you can see that you divided 10 from 10 ounces so you would do the same to the bottom ...
2.50/10 which is equal to 0.25.
Tracy goes on a 3 day and night school band trip. There is no cost for travel and each band member only pays half the cost of the hotel room. However, each person is responsible for the cost of their own meals. His portion of the hotel bill is $49 per night and Tracy leaves a 10% tip for the maid service. Before tax, Tracy spends $32 per day on eating out plus 15% of this amount in tips. If Tracy spends a total of $280.74 on the band trip, what percent tax was Tracy charged on his food?
a.
6%
b.
7%
c.
8%
d.
9%
Answers
Answer:
D
Step-by-step explanation:
The service tax that is given on the food each day is 9 %.
What does service tax mean?
The government levies a service tax on particular service transactions carried out by the service provider. Suppose x% service tax is levied on a good on $n then the total amount that is to be paid is $(n(1+x/100)).
How to solve the problem?
Let the percent service tax that is charged on food be x%.
The situation is The total expenditure is $280.74 which is $49 per day on the hotel bill for 3 days on which a 10% tip was given for the maid services each day.
$32 was spent each day on food plus 15% of that amount was given as a tip each day.
And x% of $32 was given on tax.
Then, the equation that best represents the given situation is
280.74/3=49+(0.10)(49)+32+(0.15)(32)+(x/100)(32)
Then 93.58=90.7+(32)(x/100)
⇒32x=2.88×100
⇒x=288/32=9%
Thus, the service tax that is charged on the food each day is 9 %.
