Answer:

The unit rate is 1.5

Step-by-step explanation:

Given

Ratio = 4/7 : 8/21

Required

Determine the unit rate

To do this, we need to express the ratio as:

Ratio = m : 1

<em>Where m is the unit rate</em>

Ratio = 4/7 : 8/21

Express as fraction

Ratio = \frac{4/7 }{ 8/21}

Solve

Ratio = \frac{4}{7} * \frac{21}{8}

Ratio = 1.5

Express as ratio

Ratio = 1.5 : 1

<em>Hence, the unit rate is 1.5</em>

Express each of these system specifications using predicates, quantifiers, and logical connectives, if necessary.
Alja [10]

Step-by-step explanation:

1. we have to write the system specifications as:

A(x,y) give us the meaning that the consule x can be accessed when y is in a faulty condition

∀y∃A(x,y)

2. B(x,y) shows that users email has sent a message, y. Which is in the archive. C(x) shows the email address of user x is retrievable

∀x∃y[B(x,y)→c(x)]

3. D(x,y) shows that x can detect breach y'' and we have E(z) that tells us there is a compromise of z

∀y∃xD(x,y)↔ ∃zE(z)

4. F(x,y,z)

Y and z are distinct point ends which x connects

We have,

∀y∀z∃x∃a[x ≠a →F(x,y,z)^F(a,y,z)

5. G(x,y)

X knowst the password of y' and H(x) means that we have x to be a system administrator

∀x[H(x)→∀yG(x,y)] ∃x[H(x)^∀yG(x,y)]
