Step-by-step explanation:

In the given cube-shaped cake, the value of c + s = 32/5.

In the given figure of the cube-shaped cake, let [RNQ] be the area of the triangle RNQ. The volume of the corresponding piece c = 2[RNQ]. The cake piece has icing on the top and on the vertical side that contains the edge QR. Hence the total area with icing is [RNQ] + 2^2 = [RNQ] + 4. Hence, c+s = 3[RNQ] + 4.

In order to determine [RNQ], introduce a coordinate system. Let Q be the origin. As the length of each edge is 2. Hence,

Q = (0,0)

P = (2, 0)

R = (0, 2)

In the coordinate system, as M is the midpoint of PS, M = (2, 1). The equation of the line QM is:

m = (1- 0)/(2 – 0) = ½

y – 0 = ½(x – 0)

2y – x = 0

As the line RN is orthogonal to QM, it has an equation is y + 2x + q = 0. As the point R lies on the line RN,

2 + 2(0) + q = 0

q = -2

Hence, RN is y + 2x -2 = 0

Substituting x = 2y into the line RN,

y + 2(2y) -2 = 0

5y = 2

y = 2/5

x = 2(2/5) = 4/5

In the triangle RNQ, x is the height from N onto RQ, the area [RNQ] = (x*RQ)/2 = 2x/2 = x = 4/5.

Hence, 3[RNQ] + 4 = 3(4/5) + 4 = 32/5.

Note: The question is incomplete. The complete question probably is: A cubical cake with edge length 2 inches is iced on the sides and the top. It is cut vertically into three pieces as shown in this top view, where M is the midpoint of a top edge. The piece whose top is triangle B contains c cubic inches of cake and s square inches of icing. What is c+s?

Step-by-step explanation:

Given that :

Mean = 76mph

Standard deviation = 7 mph

Percentage of cars traveling slower than 55mph

Obtain the Zscore :

X = 55mph

Zscore = (X - mean) / standard deviation

Zscore = (55 - 76) / 7

Zscore = - 3

P(Z < - 3)

From the z table :

Answer:

we conclude that:

Step-by-step explanation:

A dilation is a transformation which generates an image that is the same shape as the original object but in a different size.

The image can be obtained by multiplying the measure of the original object by a scale factor.

If the scale factor > 1, the image is stretched

If the scale factor < 1, the image is reduced

If the scale factor = 1, the image and object will be congruent

For example, if we multiply the measure of the coordinates of the vertex A(2, 2) of a triangle by a scale factor of 2, the image A' is stretched as the scale factor > 1.

Dilation with scale factor 2, multiply by 2.

A(2, 2) → (2(2), 2(2)) = A'(4, 4)

So, the image point A'(4, 4) is enlarged.

Dilation with scale factor ½, multiply by ½.

A(2, 2) → (2(1/2), 2(1/2)) = A'(1, 1)

So, the image point A'(1, 1) is reduced.

Therefore, we conclude that:

Based on the truth table, we can say that the conclusion is not a tautological consequence of the premises.

To determine whether the conclusion is a tautological consequence of the premises, we need to evaluate the truth values of the propositions involved using a truth table.

Let's construct a truth table with columns for P1 (Large(a)), P2 (Cube(a)), P3 (Dodec(a)), and the conclusion [P1 ∨ P3 ∧ (P2 ∨ P1)].

P1 P2 P3 (P1 ∨ P3 ∧ (P2 ∨ P1))

F T T T

F T F F

F F T F

F F F F

In the truth table, we can see that the conclusion is true in some cases where the premises are true (rows 1-4). However, it is also false in some cases where the premises are true (rows 5-8).

A tautological consequence would mean that the conclusion is true for all possible combinations of truth values for the premises. Since there are cases where the conclusion is false while the premises are true, it does not meet the criteria for a tautological consequence.

The effect of tripling the sample size while keeping the confidence level the same would be to reduce the margin of error from 0.09 to 0.049, and to narrow the confidence interval from (0.23, 0.41) to (0.263, 0.361).

Assuming that the sample is a simple random sample, we can use the formula for the confidence interval for a proportion:

Confidence interval = sample proportion ± margin of error

where the margin of error is:

Margin of error = z* (standard error)

and z* is the z-score corresponding to the desired level of confidence (in this case, 90%). For a 90% confidence interval, the z* value is 1.645.

The formula for the standard error is:

\(Standard error = \sqrt{[(sample proportion \times (1 - sample proportion)) / sample size]}\)

Using the information given, we can write:

0.23 ≤ sample proportion ≤ 0.41

z = 1.645

We can solve for the sample proportion as follows:

\((sample proportion \times (1 - sample proportion)) / sample size = (1.645 / 2.0)^2\)

Solving this equation gives:

\(sample size = (1.645 / 0.09)^2 \times (0.41 * 0.59)\)

So, tripling the sample size would give us a new sample size of 3 * 50 = 150.

Using the same formula for the confidence interval, but with the new sample size, we get:

\(Margin of error = 1.645 \times \sqrt{ [(sample proportion \times (1 - sample proportion)) / sample size]}\)

Setting the margin of error equal to 0.09 (the margin of error for the original sample), we can solve for the new sample proportion:

0.09 = 1.645 * sqrt [(sample proportion * (1 - sample proportion)) / 150]

Solving for the sample proportion gives:

sample proportion = 0.312

The encryption method that combines a random value with the plain text to produce the cipher text is: One-time pad.

The one-time pad encryption technique is a form of symmetric encryption where a random key, known as the one-time pad, is combined with the plain text using a bitwise XOR operation. The one-time pad should be at least as long as the plain text and should never be reused.

In this method, each character of the plain text is combined with a corresponding character from the one-time pad, resulting in the cipher text. The one-time pad acts as a random key stream, making the encryption extremely secure if implemented correctly.

Steganography is a different technique that involves hiding information within other seemingly innocuous data, such as images or audio files, without necessarily encrypting it.

Transposition is a method of encryption where the characters of the plain text are rearranged or shuffled without changing the actual characters themselves.

Elliptic Curve is not an encryption method but rather a mathematical framework used in public-key cryptography systems, such as Elliptic Curve Cryptography (ECC), which provide secure communication channels but do not involve combining random values with the plain text to produce the cipher text.

The correct answer is the volume of water (in liters) pumped in during the first minute is 7.766 liters.

Given a pump is delivering water into a tank at a rate of r (t) 3t2+5 liters/minute where t is the time in minutes since the pump was turned on. Using a left Riemann sum with n 5 subdivisions to estimate the volume of water pumped in during the first minute.

We need to calculate the left Riemann sum first.

Let's find the width of each subdivision first: ∆t=(b-a)/n where a=0, b=1, and n=5.

∆t= (1-0)/5=0.2

Next, let's calculate the height of each subdivision using left endpoints: r(0)

= 3(0)^2 + 5

= 5r(0.2)

= 3(0.2)^2 + 5

= 5.24r(0.4)

= 3(0.4)^2 + 5

= 6.4r(0.6)

= 3(0.6)^2 + 5

= 7.8r(0.8)

= 3(0.8)^2 + 5

= 9.4

We have the width and height of each subdivision, so now we can calculate the left Riemann sum:

LRS = f(a)∆t + f(a + ∆t)∆t + f(a + 2∆t)∆t + f(a + 3∆t)∆t + f(a + 4∆t)∆t where a=0, ∆t=0.2

LRS = r(0)∆t + r(0.2)∆t + r(0.4)∆t + r(0.6)∆t + r(0.8)∆t

= 5(0.2) + 5.24(0.2) + 6.4(0.2) + 7.8(0.2) + 9.4(0.2)

= 1 + 1.048 + 1.28 + 1.56 + 1.88

The two numbers whose sum is 495 and follows the required conditions are 450 and 45.

Let the two numbers be "AB0" and "AB," where A and B are digits, and 0 represents a zero.

The sum of the two numbers is equal to 495.

The last digit of one of the numbers is zero, which means the first number is a multiple of 10, so we can rewrite it as 10x.

If you cross off the zero from the first number, you get the second number, so the second number is AB.

Now, let's substitute the values into the equation:

10x + x = 495

Now, add the like terms, and we get,

11x = 495

The equation f(x) = e^x - 2x^2 has no solutions. To find the number of solutions for the equation f(x) = 0, where f(x) = e^x - 2x^2, we will use the methods of differential calculus.

Step 1: Find the derivative of f(x):

f'(x) = d/dx (e^x - 2x^2)

      = e^x - 4x

Step 2: Set the derivative equal to zero and solve for x:

e^x - 4x = 0

Step 3: Determine critical points:

To find the critical points, we need to solve the equation e^x - 4x = 0. However, this equation cannot be solved algebraically. We can use numerical methods or approximation techniques to find the critical points.

One of the critical points is x ≈ 0.703467.

Step 4: Determine the sign of the derivative intervals:

To determine the intervals where the derivative is positive or negative, we can choose test points within each interval. We'll test points to the left and right of the critical point x ≈ 0.703467.

For x < 0.703467, we can choose x = 0 as a test point:

f'(0) = e^0 - 4(0) = 1 > 0

So, f'(x) > 0 for x < 0.703467.

For x > 0.703467, we can choose x = 1 as a test point:

f'(1) = e^1 - 4(1) = e - 4 < 0

So, f'(x) < 0 for x > 0.703467.

Step 5: Analyze the number of solutions:

Based on the sign of the derivative, we can conclude that f(x) is increasing to the left of x ≈ 0.703467 and decreasing to the right of x ≈ 0.703467. This implies that f(x) has one local minimum at x ≈ 0.703467.

To determine the number of solutions for f(x) = 0, we need to analyze the behavior of f(x) around the critical point:

- If f(x) changes sign from negative to positive at x ≈ 0.703467, then there is one solution.

- If f(x) does not change sign around x ≈ 0.703467 (i.e., f(x) remains negative or zero), then there are no solutions.

Step 6: Evaluate f(x) at x = 0:

f(0) = e^0 - 2(0)^2 = 1 > 0

Since f(x) is positive at x = 0, it does not change sign around x ≈ 0.703467. Therefore, there are no solutions to f(x) = 0 for the given function f(x) = e^x - 2x^2.

In summary, the equation f(x) = e^x - 2x^2 has no solutions.

Step-by-step explanation:

The probability that more than 210 people will pass in front of his store is 0.2272.

In the question, we are given that a coffee shop owner wants to examine the number of customers who pass in front of his store in the morning from 7:00 A.M to 7:30 A.M.

We are asked to find the probability that more than 210 people will pass in front of his store if the mean number of customers during this time is 210.

This experiment follows a Poisson Distribution with a mean (λ) = 200, and the random variable X = 210.

To find the probability that more than 210 people will pass in front of his store, we will find P(X > 200).

P(X > 200) = 1 - P(X ≤ 210).

Now, P(X ≤ 210) can be calculated using the function poissoncdf(200,210) on the calculator.

As to find the probability of a Poisson Distribution P(X ≤ x), for a mean = λ, we use the calculator function poissoncdf(λ,x).

The value of poissoncdf(200,210) = 0.77271.

Thus, the value of P(X > 210) = 1 - 0.77271 = 0.22729.

Thus, the probability that more than 210 people will pass in front of his store is 0.2272.

When light strikes a leaf, it can be absorbed by, reflected from or transmitted through the leaf. Plants appear green because they reflect and transmit slightly more green light than they do blue or red light. Chlorophyll also absorbs green light poorly.

Photosynthesis is essential to most life on Earth. Plants, algae, and some types of bacteria carry out the process by capturing solar energy to create oxygen  and chemical energy stored in glucose (a sugar). Then, herbivores get this energy from eating plants, whereas predators get it from consuming other herbivores.

Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis. Water is oxidized, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell. Water is converted into oxygen and carbon dioxide into glucose as a result. After storing energy inside the glucose molecules, the plant releases the oxygen back into the atmosphe.
