The argument is valid. The argument is valid based on the direct truth-table method.

To test the validity of the argument, we can use the direct truth-table method. Let's break down the argument and construct the truth table for the given premises and the conclusion:

Premises:

G ⊃ H

R ≡ G

~H v G

Conclusion:

R • H

Constructing the truth table:

We have three propositions: G, H, and R. Each proposition can have two truth values, true (T) or false (F). Therefore, we need 2^3 (8) rows in the truth table to evaluate all possible combinations.

By evaluating the truth table, we find that in all rows where the premises (1, 2, 3) are true, the conclusion (R • H) is also true. There is no row where the premises are true, but the conclusion is false. Therefore, the argument is valid.

The argument is valid based on the direct truth-table method. This means that if the premises (G ⊃ H, R ≡ G, ~H v G) are true, then the conclusion (R • H) must also be true.

The 21 square root of 98 divided by 7 square root of 21 = 21√98 / 7√21 = 6.4807407

A square root of a number x is a number y such that y2 = x; in other words, a number y who's square and the result of multiplying the number by itself, or y ⋅ y, is x.

Every nonnegative real number x has a unique nonnegative square root, called the principal square root, which is denoted by √where the symbol √ is called the radical sign.

Every positive number x has two square roots: √ which is positive, and -√ which is negative. The two roots can be written more concisely using the ± although the principal square root of a positive number is only one of its two square roots, the designation "the square root" is often used to refer to the principal square root.

Answer:

The price of gasoline in Paris is $6.00/gallon

Step-by-step explanation:

We are asked to find the price of gas in dollars per gallon for gasoline in Paris.

Step 1

We are told in the question that: the average price of gasoline in Paris, France, is 1.91 euros per liter.

Also we are told that, the exchange rate is 1.203 euros for one dollar

We convert the Euros to dollars

If, 1.203 euros = 1 dollar

1.91 euros = x dollars

We Cross Multiply

1.203 euros × x dollars = 1.91 euros × 1 dollar

x dollars = 1.91 euros × 1 dollar/ 1.203 euros

x dollars = 1.5876974231 dollars

Therefore, 1.203 euros = Approximately 1.59 dollars.

Hence, the price of gasoline in Paris, France is 1.59 dollars per liter.

Step 2

We convert the from liter to gallon

In the question, we are told that:

If there are 3.785 liters in one gallon

Therefore, if

1 liter of gasoline = 1.59 dollars

3.785 liters of gasoline =

Cross Multiply

= 3.785 liters × 1.59

= 6.01815 dollars.

Approximately to the nearest whole number = 6.00 dollars.

Since 3.785 liters of gasoline = 1 gallon of gasoline, therefore, the price of gas in dollars per gallon for gasoline in Paris is $6.00/gallon

The output when three workers are hired is 5 units..

To find the output when three workers are hired, we need to first determine the total cost and then use the marginal cost to calculate the output.

Find the total cost when three workers are hired.
Average total cost (ATC) = Total cost (TC) / Output (Q)
$50 = TC / Q
Since fixed cost (FC) is $130 and the marginal cost (MC) is $40 per worker, the total cost can be found by adding the fixed cost and the cost of the three workers.
TC = FC + 3(MC)
TC = $130 + 3($40)

Calculate the total cost.
TC = $130 + $120
TC = $250

Use the total cost and average total cost to find the output.
$50 = $250 / Q
Q = $250 / $50
Q = 5

Therefore, the output when three workers are hired is 5 units.

Answer:

x=+10

Step-by-step explanation:

the answer should be x=+10

The perimeter is the sum of the 4 sides:

150 = x + x + x+7 + x+7

Simplify:

150 = 4x +14

Subtract 14 from both sides:

136 = 4x

Divide both sides by 4:

x = 34

If X is 34 the perimeter would equal 150, so for the perimeter to be greater than 150, the value of x has to be greater than 34.

Answer: X >34

Since X² (68.732) > X²₀.₀₁ (13.277), we reject the null hypothesis and conclude that There is evidence that political views and level of marijuana usage are related.

The alternative hypothesis states that political beliefs and marijuana use depend on one another within the population, contrary to the null hypothesis that asserts these two variables are independent.

H₀ : Pij = Pi · Pj ; i = 1, 2, 3 ; j = 1, 2, 3

Ha : at least one Pij ≠ Pi · Pj

We want to test whether there is a relationship between political views and marijuana usage levels. The results of a random sample of size n = 1353 are derived from the following formula;

e = (Row total) x (Column total) /Total sample size

We are told to use the 0.01 level of significance to test the null hypothesis. Thus, α = 0.01. The table has r = 3 rows and c = 3 columns. An r × c table has degrees of freedom df = (r - 1) x (c - 1). So, a 3×3 table has degrees of freedom df = (3 - 1) x (3 - 1) = 4. From formula the df = 4 and α = 0.01, χ²₀.₀₁ = 13.277. Reject the null hypothesis if X² ≥ 13.277 where

x² =Σ(a - e)²/e

Substituting the observed and expected frequencies summarized in the table above into the formula for x², we get

X² = 68.732

Rejection Region → X² ≥ 13.277

Test statistic → X² = 68.732

Since X² (68.732) > X²₀.₀₁ (13.277), we reject the null hypothesis and conclude that There is evidence that political views and level of marijuana usage are related.

Answer: $23.92

Step-by-step explanation:

First, we know that 6 bagels is $2.99.

This means that 6 is a multiple of 48, which makes it easier to solve.

$2.99 x 8 = 23.92

= $23.92

The breadth of each rectangle is 11 units.

Let's consider that each rectangle has a length of l and breadth of b. We have been given that the perimeter of the shape that is formed by putting together the 4 rectangles is 88 units. We know that, the perimeter of a rectangle is given by the formula 2(l + b).

Therefore, the perimeter of the shape is given by the formula: P = 2(l + b) + 2(l + b) = 4(l + b)

From the given information, we know that the perimeter of the shape is 88.

Therefore,4(l + b) = 88

Dividing both sides of the equation by 4, we get: l + b = 22

We have found the relationship between the length and breadth of each rectangle.

Now, we need to find the value of the breadth of each rectangle.

We know that there are 4 rectangles placed side by side to form the shape.

Therefore, the total breadth of all 4 rectangles put together is equal to the breadth of the shape.

Hence, we can find the breadth of each rectangle by dividing the total breadth by the number of rectangles.

Let's denote the breadth of each rectangle as b'.

Therefore, b' = Total breadth / Number of rectangles

b' = (l + b + l + b) / 4b' = (2l + 2b) / 4b' = (l + b) / 2

We have found that the sum of the length and breadth of each rectangle is equal to 22 units.

Therefore, the breadth of each rectangle is half the sum of the length and breadth of each rectangle.

Substituting this value in the above equation, we get:b' = (l + b) / 2b' = 22 / 2b' = 11

Therefore, the breadth of each rectangle is 11 units.

To perform the calculation, we need to take the cube root of the given value, considering the absolute uncertainty.  The correct absolute uncertainty for the answer is approximately 0.010.

To determine the absolute uncertainty of the result, we need to consider the maximum and minimum values that the expression could take within the given uncertainty range.

Maximum value:

Using the upper bound of the uncertainty, the expression becomes:

[\((8.47+0.06)^{1/3}\) ≈ 2.057

Minimum value:

Using the lower bound of the uncertainty, the expression becomes:

[\((8.47+0.06)^{1/3}\)] ≈ 2.047

Therefore, the absolute uncertainty is the difference between the maximum and minimum values:

Absolute uncertainty = Maximum value - Minimum value

                   = 2.057 - 2.047

                   = 0.010

So, the correct absolute uncertainty for the answer is approximately 0.010.

If you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality sign.

A statement that upholds the equality of two mathematical expressions is known as an equation. An identity is a statement that is true regardless of the value of each variable. A conditional equation is one that only holds true for certain values of one or more variables.

On the other hand, an inequality is a claim that indicates that one quantity has a greater or lesser value than another using the symbols > for greater than or for lesser than. An inequality has values for every variable, much like an identity. It concentrates on two-variable inequalities with a single exponent.

If both sides of an inequality are multiplied or divided by a negative value, the inequality sign must be reversed. This is due to the fact that adding or subtracting a negative integer causes the numbers on the number line to appear in reverse order.
