Construction 3.17 which was EAV-Secure Prove the opposite - i.e. if G is not a PRG, then 3.17 cannot be EAV-secure. Let G be a pseudorandom generator with expansion factor ℓ. Define a private-key encryption scheme for messages of length ℓ as follows: - Gen: on input 1 n
, choose uniform k∈{0,1} n
and output it as the key. - Enc: on input a key k∈{0,1} n
and a message m∈{0,1} ℓ(n)
, output the ciphertext c:=G(k)⊕m. - Dec: on input a key k∈{0,1} n
and a ciphertext c∈{0,1} ℓ(n)
, output the message m:=G(k)⊕c. A private-key encryption scheme based on any pseudorandom generator. THEOREM 3.18 If G is a pseudorandom generator, then Construction 3.17 is a fixed-length private-key encryption scheme that has indistinguishable encryptions in the presence of an eavesdropper. PROOF Let Π denote Construction 3.17. We show that Π satisfies Definition 3.8. Namely, we show that for any probabilistic polynomial-time adversary A there is a negligible function negl such that Pr[PrivK A,Π

If G is not a PRG, then Construction 3.17 cannot be EAV-secure. This shows the contrapositive of Theorem 3.18.
To prove the opposite, we need to show that if G is not a pseudorandom generator (PRG), then Construction 3.17 cannot be EAV-secure (indistinguishable encryptions in the presence of an eavesdropper).
Let's assume that G is not a PRG. This means that there exists some efficient algorithm D that can distinguish the output of G from random strings with non-negligible advantage. We will use this assumption to construct an adversary A that can break the EAV-security of Construction 3.17.
The adversary A works as follows:
1. A receives a security parameter n.
2. A runs the key generation algorithm Gen and obtains the key k.
3. A chooses two distinct messages m0 and m1 of length ℓ(n).
4. A computes the ciphertexts c0 = G(k) ⊕ m0 and c1 = G(k) ⊕ m1.
5. A chooses a random bit b and sends cb to the challenger.
6. The challenger encrypts cb using the encryption algorithm Enc with key k and obtains the ciphertext c*.
7. A receives c* and outputs b' = D(G(k) ⊕ c*).
8. If b = b', A outputs 1; otherwise, it outputs 0.
We analyze the probability that A can distinguish between encryptions of messages m0 and m1. Since G is not a PRG, D has a non-negligible advantage in distinguishing G's output from random strings. Therefore, there exists a non-negligible function negl such that:
|Pr[D(G(k)) = 1] - Pr[D(U) = 1]| ≥ negl(n),
where U denotes a truly random string of length ℓ(n).
Now, consider the probability of A winning the PrivK game:
Pr[PrivK_A,Π
eav
(n) = 1] = Pr[b = b']
= Pr[D(G(k) ⊕ c*) = D(G(k))]
= Pr[D(G(k)) = 1]
≥ Pr[D(U) = 1] - negl(n).
Since negl(n) is non-negligible, we have:
Pr[PrivK_A,Π
eav
(n) = 1] ≥ 2^(-1) + negl(n).
Thus, if G is not a PRG, then Construction 3.17 cannot be EAV-secure. This shows the contrapositive of Theorem 3.18.

how do i solve this problem
The solution to the problem is the simplified expression: 5x³ - x² - 3x + 13.
To solve the given problem, you need to simplify and combine like terms. Start by adding the coefficients of the same degree terms.
(3x³ - x² + 4) + (2x³ - 3x + 9)
Combine the like terms:
(3x³ + 2x³) + (-x²) + (-3x) + (4 + 9)
Simplify further:
5x³ - x² - 3x + 13
In this expression, the highest power of x is ³, and the corresponding coefficient is 5. The term -x² represents the square term, -3x represents the linear term, and 13 is the constant term. The simplified expression does not have any like terms left to combine, so this is the final solution.

Which of the following three goods is most likely to be classified as a luxury good?a. Kang b. Lafgar c. Welk
Welk is most likely to be classified as a luxury good. A luxury good is a good for which demand increases more than proportionally with income.
This means that as people's incomes increase, they are more likely to spend a larger proportion of their income on luxury goods.
The income elasticity of demand for a good is a measure of how responsive demand is to changes in income. A positive income elasticity of demand indicates that demand increases as income increases, while a negative income elasticity of demand indicates that demand decreases as income increases.
The income elasticity of demand for Welk is 4.667, which is much higher than the income elasticities of demand for Kang (-3) and Lafgar (1.667). This indicates that demand for Welk is much more responsive to changes in income than demand for Kang or Lafgar.
Therefore, Welk is most likely to be classified as a luxury good.

Elliott Farms has a silo for storage. The silo is a right circular cylinder topped by a right circular cone, both having the same radius. The height of the cone is half the height of the cylinder. The diameter of the base of the silo is 10 meters and the height of the entire silo is 27 meters. What is the volume, in cubic meters, of the silo
the volume of the silo is approximately 11,657.88 cubic meters.
To find the volume of the silo, we need to calculate the volumes of the cylinder and the cone separately, and then add them together.
The radius of the base of the silo is half the diameter, so it's 10 meters / 2 = 5 meters.
The height of the cylinder is given as 27 meters. Since the height of the cone is half the height of the cylinder, the height of the cone is 27 meters / 2 = 13.5 meters.
The volume of a cylinder is calculated using the formula:
Volume of Cylinder = π * radius^2 * height
Plugging in the values, we get:
Volume of Cylinder = π * 5^2 * 27 = 3375π cubic meters (approximately 10,598.07 cubic meters)
The volume of a cone is calculated using the formula:
Volume of Cone = (1/3) * π * radius^2 * height
Plugging in the values, we get:
Volume of Cone = (1/3) * π * 5^2 * 13.5 = 337.5π cubic meters (approximately 1059.81 cubic meters)
Adding the volumes of the cylinder and the cone, we get:
Volume of Silo = 3375π + 337.5π = 3712.5π cubic meters (approximately 11,657.88 cubic meters)

A box has 15 candies in it: 9 are butterscotch, 2 are taffy, and 4 are caramel. (Each candy falls into only one of these categories.) Charmaine wants to select two candies to eat for dessert. The first candy will be selected at random, and then the second candy will be selected at random from the remaining candies. What is the probability that the first candy selected is butterscotch and the second candy is taffy? Do not round your intermediate computations. Round your final answer to three decimal places. (If necessary, consult a list of formulas.)
The probability that the first candy selected is butterscotch and the second candy is taffy can be calculated as the product of the probabilities of these two events occurring.
First, let's calculate the probability of selecting a butterscotch candy as the first candy. There are 9 butterscotch candies out of a total of 15 candies, so the probability is 9/15.Next, for the second candy to be taffy, we need to consider that one butterscotch candy has already been selected and removed from the box. Therefore, there are 14 candies remaining in the box, including 2 taffy candies. Hence, the probability of selecting a taffy candy as the second candy is 2/14.
To find the probability of both events occurring, we multiply the probabilities together: (9/15) * (2/14) = 18/210.Simplifying this fraction, we get 3/35.Therefore, the probability that the first candy selected is butterscotch and the second candy is taffy is 3/35, which is approximately 0.086 or rounded to three decimal places.

What equation represents a line that passes through (2,-1/2) and has a slope of 3.
There is a line through the origin that divides the region bounded by the parabola y=5x−3x^2 and the x-axis into two regions with equal area. What is the slope of that line?
The slope of the line that divides the region bounded by the parabola \(y=5x-3x^2\)and the x-axis into two regions with equal area is 5.
To find the slope of the line that divides the region into two equal areas, we need to determine the point of intersection between the parabola and the x-axis. Since the line passes through the origin, its equation will be y = mx, where m represents the slope.
Setting the equation of the parabola equal to zero, we find the x-values where the parabola intersects the x-axis. By solving the equation\(5x - 3x^2 = 0\), we get x = 0 and x = 5/3.
To divide the region into two equal areas, the line must pass through the midpoint between these x-values, which is x = 5/6. Plugging this value into the equation of the line, we have y = (5/6)m.
Since the areas on both sides of the line need to be equal, we can set up an equation using definite integrals. By integrating the equation of the parabola from 0 to 5/6 and setting it equal to the integral of the line from 0 to 5/6, we can solve for m. After performing the integration, we find that m = 5.
Therefore, the slope of the line that divides the region into two equal areas is 5.

Kelsey says that to solve the equation 3x + 6 = 24, the first step should be to subtract 6 from each side of the equation. Dana says the first step should be to divide each term by 3. Decide and explain if Kelsey or Dana is doing the first step correctly.
Answer:
Kelsey is correct.

One of the rules when solving an equation is that you need to isolate the variable, meaning that it just needs to be x by itself. To do that, you would need to start by subtracting 6. If you were to divide by 3 first, the answer would be twice what it should be.

(a). The value of p is 0.75.
(b). The value of ^p is 0.787.
(c). The value of standard deviation of ^p is 0.035.
What is standard deviation?
The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation implies that the values are dispersed over a wider range, a low standard deviation shows that the values tend to be close to the mean of the collection.
As given,
The students that graduated from their school in the past 5 years is 150.
The students that immediately to college after graduation is 118.
a) Evaluate the value of p.
p = 0.75 (75% is given).
b) Evaluate the value of ^p.
^p = 118/150
^p = 0.787
Hence, answer is 0.787 (rounded to 3 decimal places).
c) Evaluate the standard deviation of the sampling distribution of ^P.
SD = √ [^p*(1 - ^p)/n]
Substitute values respectively,
SD = √ [0.787*(1 - 0.787)/150]
SD = 0.035
So, standard deviation of the sampling distribution of ^p is 0.035.

The hypotenuse of a right triangle measures 16 cm and one of its legs measures 11 cm. Find the measure of the other leg.
Answer:
The answer is 11.6 cm
Step-by-step explanation:
The equation of a right triangle is a^2+b^2=c^2 (a and b being its legs and c its hypothenuse.)
Now we must input 16 cm into c and 11 cm into either a or b.
a^2+11^2=16^2 which is equal to a^2+121=256.
subtract 121 from both sides to get a^2 by itself
a^2+(121-121)=(256-121)
a^2=135
to get "a" by itself, we must find the square root of 135.

A colony of 30,000 bacteria doubles in size every 29 hours. what will the population be 58 hours from now
This is an example of exponential growth.
Since the population doubles in size every 29 hours,
and the initial population is 30000,
then in 29 hours,
the population = 30000 x 2 = 60000
and in
another 29 hours (total of 58 hours from the start),
the population = 60000 x 2 = 120000
Hence the population after 58 hours is 120000 bacteria.
what is wrong with the following "proof" of the statement that √ n is irrational for every natural number n? "proof ". suppose that √ n is rational, say √ n
The given "proof" is incomplete and does no longer provide a convincing argument for the statement that \(\sqrt{n}\) is irrational for every natural wide variety of n.
It begins by assuming that \(\sqrt{n}\) is rational, represented as \(\sqrt{n}\) = a/b, wherein a and b are integers and not using common factors and b isn't equal to zero.
The blunders in this evidence lie within the assumption that \(\sqrt{n}\) can be represented as a rational number. The evidence fails to expose a contradiction or offer proof that \(\sqrt{n}\) can not be expressed as a ratio of integers. In order to prove that \(\sqrt{n}\) is irrational, one has to show that there are not any viable values for a and b that satisfy the equation √n = a/b.
To establish the irrationality of \(\sqrt{n}\), legitimate evidence usually utilizes techniques along with evidence with the aid of contradiction or evidence by means of high factorization. These techniques involve assuming that \(\sqrt{n}\) is rational, manipulating the equation, and deriving a contradiction or showing that the idea results in a not possible situation.
Since the given proof lacks those crucial elements, it can't establish a declaration that \(\sqrt{n}\) is irrational for each natural range n.
