There exists a row where all the premises are true but the conclusion is false, the argument is invalid. Therefore, the correct answer is: d. Invalid.

To determine the status of the argument using indirect truth tables, we need to construct a truth table and evaluate the argument's validity.

We assign truth values to the propositions: Q, S, N, A, P, and G. We consider all possible combinations of truth values and evaluate the truth value of each statement in the argument.

Using indirect truth tables, we construct the following truth table:

Q | S | N | A | P | G | ∼ S | ∼(N • A) | S ∨ A | (P • N) ∨ (G • Q) | P • G

------------------------------------------------------------------------

T | T | T | T | T | T | F   | F          | T      | T                  | T

T | T | T | T | T | F | F   | F          | T      | T                  | F

T | T | T | T | F | T | F   | F          | T      | T                  | F

T | T | T | T | F | F | F   | F          | T      | F                  | F

... (continued for all possible combinations)

We can see that there is at least one row in the truth table where all the premises are true and the conclusion is false. Specifically, when Q = T, S = T, N = T, A = T, P = F, and G = F, the premises are true (Q ∨ ∼S, ∼(N • A), S ∨ A, (P • N) ∨ (G • Q)), but the conclusion (P • G) is false.

Since there exists a row where all the premises are true but the conclusion is false, the argument is invalid.

Therefore, the correct answer is:

d. Invalid.

Answer:

\(\mathbf{\beta=140\ dB}\)

Step-by-step explanation:

The Logarithm Function

The sound level is usually calculated as a logarithm by the formula:

\(\displaystyle \beta=10\log\frac{I}{I_o}\)

Where

I   = Sound intensity in W/square meter

Io = Smallest sound intensity that can be heard.

\(I_o=1\cdot 10^{-12}\ W/m^2\)

The blue whale can emit a sound of I=106.8 W/square meter, thus the sound level is:

\(\displaystyle \beta=10\log\frac{106.8}{1\cdot 10^{-12}}\)

\(\displaystyle \beta=10*14\)

\(\mathbf{\beta=140\ dB}\)

Answer:

There are 33 cows and 26 chickens

Step-by-step explanation:

Problem Solving

This problem can easily be solved by using equations, but it's more fun to solve it through pure reasoning and arithmetics.

Let's imagine there are no cows on the farm. Just chickens. 59 chicken heads mean 59*2 = 118 legs.

Now let's take one chicken out and one cow in. The number of heads will remain the same, but now there are two more legs: 120 legs.

We are closer to the answer. The trick is to calculate how many chickens we have to exchange for cows knowing each change means two more legs.

Since we initially had 118 legs, we need to add 184 - 118 = 66 more legs.

62 more legs are 66/2 = 33 changes or 33 cows.

The number of chickens is 59 - 33 = 26

From the given question above we can conclude that when 6x +16 += 2x+28 , then the value of x is 3.

What is Linear Equation?

A linear equation is a mathematical expression in which the highest power of the variable is 1. It can be written in the form of:

y = mx + b

where y and x are variables, m is the slope of the line, and b is the y-intercept of the line. This form is called the slope-intercept form of a linear equation.

To solve the equation 6x + 16 = 2x + 28:

Simplify both sides of the equation by combining like terms:

6x + 16 = 2x + 28

Subtract 2x from both sides:

4x + 16 = 28

Subtract 16 from both sides:

4x = 12

Solve for x by dividing both sides by 4:

4x = 12

x = 3

Therefore, the solution to the equation 6x + 16 = 2x + 28 is x = 3.

The slope of the equation of the line 3f - s = 24 is 3.

The equation of a line can be represented in slope intercept form as follows:

y = mx + b

where

Therefore, let's model the equation of the line y = mx + b to 3f - s = 24. Then, we can locate the slope in the equation.

Hence,

3f - s = 24.

add s to both sides of the equation

3f - s + s = 24 + s

3f = 24 + s

subtract 24 from both sides of the equation

3f = 24 + s

3f - 24 = 24 - 24 + s

s = 3f - 24

Therefore, the slope is 3.

The probability that a value selected at random from a normal distribution with a mean of 100 and a standard deviation of 10 is at least 80 can be calculated using the standard normal distribution table or by standardizing and using the z-score formula. The probability is approximately 0.9772 or 97.72%.

To find the probability that a value is at least 80, we need to calculate the area under the normal curve to the left of 80. We can do this by standardizing the value using the z-score formula:

z = (x - μ) / σ

where x is the value, μ is the mean, and σ is the standard deviation. In this case, x = 80, μ = 100, and σ = 10.

Calculating the z-score:

z = (80 - 100) / 10

  = -20 / 10

  = -2

Using the standard normal distribution table or a calculator, we find that the area to the left of a z-score of -2 is approximately 0.0228.

Since we want the probability that the value is at least 80, we subtract the area to the left from 1:

P(X ≥ 80) = 1 - 0.0228

               = 0.9772

Therefore, the probability that a value selected at random from the given normal distribution is at least 80 is approximately 0.9772 or 97.72%.

Answer:

Step-by-step explanation:

let t be tennis balls and g be golf balls, then

5t + 3g = 70 → (1)

2t + 5g = 85 → (2)

Multiplying (1) by 5 and (2) by - 3 will eliminate g

25t + 15g = 350 → (3)

- 6t - 15g = - 255 → (4)

Add (3) and (4) term by term to eliminate g

19t = 95 ( divide both sides by 19 )

t = 5

Substitute t = 5 into either of the 2 equations and solve for g

Substituting into (1)

5(5) + 3g = 70

25 + 3g = 70 ( subtract 25 from both sides )

3g = 45 ( divide both sides by 3 )

g = 15

We need to know the size of the pieces in order to calculate how many people can be fed equal-sized pieces of cake from a 16 by 18-inch cake.

Assume that each piece is a square with sides measuring "x" in length. Each piece's area would be x², and the cake's overall area would be 16 x 18 inches, or 288 square inches.

We must divide the entire area of the cake by the area of each piece to determine the maximum number of pieces that can be cut from the cake:

288 / x² = (16*18) / x² = 288 / x²

Choosing a "x" value that evenly splits into 16 and 18 is necessary if we want every piece to be the exact same size. Since 2 is the greatest possible value, we can divide the cake into 8 rows of 9 squares, yielding a total of 72 pieces.

As a result, a cake measuring 16 inches by 18 inches can be divided into 72 equal-sized pieces, each measuring 2 inches by 2 inches.

We can serve 18 people equal-sized pieces of cake from a cake that is 16 inches by 18 inches, assuming each piece is a square and we want the pieces to be exactly the same size.

A two-dimensional figure, form, or planar lamina's area is a measurement of how much space it takes up in the plane.

To find out how many people can be served equal-sized pieces of cake from a cake that is 16 inches by 18 inches, we need to first determine the size of each piece of cake.

The total area of the cake is:

16 inches x 18 inches = 288 square inches

To divide the cake into equal-sized pieces, we need to determine the size of each piece. Let's assume we want each piece to be a square. To find the size of each square, we need to find the square root of the total area of the cake:

√(288 square inches) ≈ 16.97 inches

Since we want the pieces to be exactly the same size, we'll round down to the nearest inch, which gives us:

Each piece of cake will be approximately 16 inches by 16 inches.

To find out how many people can be served equal-sized pieces of cake, we need to divide the total area of the cake by the area of each piece:

288 square inches ÷ (16 inches x 16 inches) = 18

Therefore, we can serve 18 people equal-sized pieces of cake from a cake that is 16 inches by 18 inches, assuming each piece is a square and we want the pieces to be exactly the same size.
