Answer:

Case1:

Men : 30

Work : 1

Time (day×hr): 56×6 = 336 hr.

Case2:

Men : let it be m men.

Work: 1

Time: 45×7 = 315 hr.

Work being constant in both cases, men and time are in inverse proportion i.e, more men take less time.

Product of men and time is constant in both cases.

Therefore, 30×336=m×315

Or, 30×336/315 = m

Or, m = 32.

Hence, required number of men is 32.

The Area of the object is 172 inches square

According to the question,

The length of Y = 14 inches

Z = 19 inches

H = 6 inches

and W = 4 inches

Dividing the object into two rectangle( 1st and 2nd )

So , The area of 1st rectangle = Length × width

=> Area of 1st = W × Y

=> 14 × 4 = 56 inches

Now, The Width of 2nd part = Y - H

=> 14 - 6

=> 8 inches

The length of 2nd part = Z - W

=> 19 - 4

=> 15 inches

Therefore, the area of 2nd rectangle = 8 * 15

=> 120 inches

So, the area of Object = area of 1st rectangle + area of 2nd rectangle

=> 120 + 56

=>176 inches square

To find the exact value of the volume of the solid obtained by rotating the region bounded by y = √x, x = 2, x = 6 and y = 0, about the x-axis, we will use the method of cylindrical shells. The exact value of the volume of the solid obtained by rotating the region bounded by y = √x, x = 2, x = 6 and y = 0, about the x-axis is (4/5)π(6^(5/2) - 2^(5/2)).

First, we need to determine the height of each cylindrical shell. Since we are rotating the region about the x-axis, the height of each cylindrical shell is simply the distance between the x-axis and the function y = √x. Thus, the height of each shell is given by h = √x.
Next, we need to determine the radius of each cylindrical shell. The radius of each shell is the distance from the x-axis to a given x-value. Thus, the radius of each shell is given by r = x. The thickness of each cylindrical shell is dx.
The volume of each cylindrical shell is given by the formula V = 2πrhdx. Substituting the expressions for h and r, we get:
V = 2πx(√x)dx
Integrating this expression from x = 2 to x = 6 gives us the total volume of the solid:
∫2^6 2πx(√x)dx = 2π∫2^6 x^(3/2)dx
Using the power rule of integration, we get:
2π(2/5)x^(5/2) evaluated from x = 2 to x = 6
Simplifying this expression, we get:
(4/5)π(6^(5/2) - 2^(5/2))
Therefore, the exact value of the volume of the solid obtained by rotating the region bounded by y = √x, x = 2, x = 6 and y = 0, about the x-axis is (4/5)π(6^(5/2) - 2^(5/2)).

The equation with the fewest symbols is 30x - 18, which represents the simplified form of the given expression.

An equation is a mathematical statement that shows the equality between two expressions. The given expression is not an equation since there is no equality sign present. However, we can simplify the expression to get an equivalent equation with the fewest symbols.

To simplify the expression, we use the distributive property of multiplication over addition/subtraction. We multiply 6 with each term inside the parentheses, i.e., 5x and -3. This gives us:

6(5x - 3) = 6(5x) - 6(3) = 30x - 18

This simplified expression is an equation that shows the equality between the left-hand side (LHS) and the right-hand side (RHS). The LHS is 30x - 18, and the RHS is also 30x - 18, which means that they are equal.

Therefore, the equation with the fewest symbols is 30x - 18, which represents the simplified form of the given expression.

The measure of the angle G will be equal to 27.50°.

The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry. The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.

Given that in ΔFGH, f = 880 inches, g = 450 inches, and h=890 inches.

The value of the angle G will be calculated as,

g² = h² + f² -2hfcosG

450² = (890)² + (880)² - 2(890)(880)cosG

202500 = 792100 + 774400 + 1566400cosG

cosG = ( 1364000) / ( 12 x 890 x 880 )

cosG = 0.87

G = cos⁻¹(0.87)

G = 27.50°

Therefore, the measure of the angle G will be equal to 27.50°.

Step-by-step explanation:

At a 90% confidence level, the population mean is estimated to fall between 12.159 and 12.641 confidence intervals using the t-distribution.

A confidence interval is a range of values that is believed to contain the true value of a parameter with a certain degree of confidence. The confidence level, the sample size, the sample mean, and the standard deviation are used to calculate a confidence interval.

The formula for a confidence interval is:

CI = x ± tα/2 * (s/√n)

where

Let's apply the formula to the given problem:

We need to find the confidence interval for the population mean using the t-distribution. We know that the confidence level is 0.90. Therefore_

The degrees of freedom = n - 1

The degrees of freedom = 17 - 1 = 16

we can get tα/2 with 16 degrees of freedom at the 0.05 significance level from the t-distribution table or calculator. It is 1.746.

Using the formula for the confidence interval, we have:

CI = x ± tα/2 * (s/√n)

CI = 12.4 ± 1.746 * (0.57/√17)

CI = 12.4 ± 0.241

CI = (12.159, 12.641)

Therefore, the confidence interval for the population mean y is (12.159, 12.641) using the t-distribution at the 90% confidence level.

There is no positive integer whose echo is a perfect square.

Let's assume that there exists a positive integer n whose echo is a perfect square. Then the echo of n can be written as \(10^k * n + n\), where k is the number of digits in n.

Now we can write the equation as:

\(10^k * n + n = m^2\)

where m is a positive integer representing the perfect square.

We can factor out n from the left-hand side to get:

\(n(10^k + 1) = m^2\)

Since n is a positive integer, the factors \((10^k + 1)\)and \(m^2\) must also be positive integers. This means that \(10^k + 1\) is a positive integer that is a perfect square.

However, for any positive integer k, the numbers \(10^k\) and \(10^k + 1\) are consecutive integers, and there are no perfect squares between consecutive integers except for the cases where the smaller integer is 0 or 1. Since \(10^k\) is always greater than 1, it follows that there cannot exist a positive integer whose echo is a perfect square.

Therefore, there is no positive integer whose echo is a perfect square.

A sampling distribution, also known as a finite-sample distribution, in statistics is the probability distribution of a given random-sample-based statistic. The sampling distribution is the probability distribution of the values that the statistic takes on if an arbitrarily large number of samples, each involving multiple observations (data points), were used separately to compute one value of a statistic (such as, for example, the sample mean or sample variance) for each sample. Although only one sample is frequently observed, the theoretical sampling distribution can be determined.

Because they offer a significant simplification before drawing conclusions using statistics, sampling distributions are crucial in the field. They enable analytical decisions to be made based on the probability distribution of a statistic rather than the combined probability distribution of all the individual sample values

The subspace W of R^3, given by W = {(a, 2a, b)}, has a basis {(1, 2, 0), (0, 0, 1)} and dimension 2.

(a) To show that W is a subspace of R^3, we need to prove three conditions: closure under addition, closure under scalar multiplication, and containing the zero vector.

Closure under addition:

Let u = (a, 2a, b) and v = (c, 2c, d) be vectors in W. The sum of u and v is given by (a + c, 2a + 2c, b + d). Since a + c, 2a + 2c, and b + d are all real numbers, (a + c, 2a + 2c, b + d) is also in the form of (a, 2a, b), which means it belongs to W. Therefore, W is closed under addition.

Closure under scalar multiplication:

Let u = (a, 2a, b) be a vector in W, and let k be a scalar. The scalar multiple of u is given by k(u) = (ka, 2ka, kb). Since ka, 2ka, and kb are all real numbers, k(u) is also in the form of (a, 2a, b), which means it belongs to W. Therefore, W is closed under scalar multiplication.

Containing the zero vector:

The zero vector is (0, 0, 0). Substituting a = 0 and b = 0 into the form (a, 2a, b), we get (0, 0, 0). Therefore, the zero vector is in W.

Since W satisfies all three conditions, it is a subspace of R^3.

(b) To find a basis for W, we need to determine a set of vectors that are linearly independent and span W. Let's consider the vector (1, 2, 0) and (0, 0, 1).

To show linear independence, we set up the equation:

c1(1, 2, 0) + c2(0, 0, 1) = (0, 0, 0)

This gives us the system of equations:

c1 = 0

2c1 = 0

c2 = 0

From this, we can see that c1 = c2 = 0 is the only solution. Therefore, the vectors (1, 2, 0) and (0, 0, 1) are linearly independent.

To show that they span W, we need to show that any vector in W can be expressed as a linear combination of these basis vectors.

Let (a, 2a, b) be an arbitrary vector in W. We can express it as:

(a, 2a, b) = a(1, 2, 0) + b(0, 0, 1)

Therefore, the vectors (1, 2, 0) and (0, 0, 1) span W.

Therefore, a basis for W is {(1, 2, 0), (0, 0, 1)}.

(c) The dimension of a subspace is equal to the number of vectors in its basis. In this case, the basis for W is {(1, 2, 0), (0, 0, 1)}, which contains 2 vectors. Therefore, the dimension of W is 2.

The correct answer is B. Fe(s) (Iron in solid state). Fe(s) as it does not have a standard heat of formation value of zero at 25°C and 1.0 atm.

The standard heat of formation (ΔH°f) is the enthalpy change that occurs when one mole of a substance is formed from its elements in their standard states at a specified temperature and pressure. A standard heat of formation value of zero at 25°C and 1.0 atm means that the formation of the substance from its elements does not release or absorb heat under these conditions.

In the case of A. N2(g) (Nitrogen gas), C. Ne(g) (Neon gas), and D. H(g) (Hydrogen gas), these are all elemental gases at standard conditions, and their standard heat of formation is zero. This means that the formation of one mole of these gases from their respective elements (N2, Ne, and H2) does not result in any heat release or absorption.

However, B. Fe(s) (Iron in solid state) does not have a standard heat of formation value of zero. The formation of solid iron from its elements (Fe atoms) does involve an enthalpy change, as there is a significant amount of energy involved in the formation of metallic bonds in the solid state.

Therefore, the correct option is B. Fe(s) as it does not have a standard heat of formation value of zero at 25°C and 1.0 atm.
