Therefore , the solution of the given problem of inequality comes out to be  150 units per employee, to satisfy the production demand.

Despite the fact that algebra lacks a comparable symbol, its distinction can be expressed by a pair or collection for numbers. Equilibrium is typically followed by equity. The ongoing disparity in norms is what causes inequality. Disparity and fairness are not synonymous. Even though the components are typically not connected or situated closely together, that was our most popular symbol.

Here,

A) Assume Y is the number of units created and X is the number of employees. The following inequalities represent the circumstances in the issue:

=> 100 ≤ X ≤ 200 (the factory must have at least 100 but no more than 200 workers)

=> Y ≥ 30X (the factory must manufacture at least 30 units per worker)

B) The lines 100, 200, and 30X would form the borders of the darkened area.

C) The following three options meet the set of inequalities:

=> X = 100, Y = 3000

The product \($A \times B \times C \times D$\) is: \($3 \times 7 \times 2.5 \times 10 = \boxed{525}$\)

We start by finding the values of \(A$, $B$, $C$\)and \($D$\). From the given conditions, we have:

\($A+2 = B-2 \Rightarrow B = A+4$\)

\($C \times 2 = A+2 \Rightarrow C = \frac{A+2}{2}$\)

\($D \div 2 = A+2 \Rightarrow D = 2A+4$\)

Substituting these values into the equation for the sum of the four integers, we get:

\($A + (A+4) + \frac{A+2}{2} + 2A+4 = 36$\)

Simplifying the expression, we get:

\($7A + 14 = 36$\)

\($7A = 22$\)

The integral: S1 0 (-x³ - 2x² - x + 3)dx is -1/12

An integral is a mathematical operation that calculates the area under a curve or the value of a function at a specific point. It is denoted by the symbol ∫ and is used in calculus to find the total amount of change over an interval.

To evaluate the integral:

\($ \int_0^1 (-x^3 - 2x^2 - x + 3)dx $\)

We can integrate each term of the polynomial separately using the power rule of integration, which states that:

\($ \int x^n dx = \frac{x^{n+1}}{n+1} + C $\)

where C is the constant of integration.

So, we have:

\($ \int_0^1 (-x^3 - 2x^2 - x + 3)dx = \left[-\frac{x^4}{4} - \frac{2x^3}{3} - \frac{x^2}{2} + 3x\right]_0^1 $\)

Now we can substitute the upper limit of integration (1) into the expression, and then subtract the result of substituting the lower limit of integration (0):

\($ \left[-\frac{1^4}{4} - \frac{2(1^3)}{3} - \frac{1^2}{2} + 3(1)\right] - \left[-\frac{0^4}{4} - \frac{2(0^3)}{3} - \frac{0^2}{2} + 3(0)\right] $\)

Simplifying:

\($ = \left[-\frac{1}{4} - \frac{2}{3} - \frac{1}{2} + 3\right] - \left[0\right] $\)

\($ = -\frac{1}{12} $\)

Therefore,

The condition that ensures a solution for the mentioned equation is :

1. b₂ = 2b₁ and 6b₁-3b₃ +b₄ = 0.

In mathematics, an equation is a formula that connects two expressions with the equal sign = to indicate that they are equal. An equation consists of two expressions joined by an equal sign ("="). Expressions for both sides of the equals sign are called the "left side" and the "right side" of the equation. Usually the right side of the equation is assumed to be zero. If this is accepted, it does not reduce the generality, since it can be done by subtracting the right side from the two sides.

According to the Question:

Given that:

x₁+ 2x₂= b₁       ------------------------- (1)

2x₁ + 4x₂ = b₂  ------------------------- (2)

3x₁ + 7x₂ = b₃   ------------------------ (3)

3x₁ + 9x₂ = b₄   ------------------------ (4)

From equation (1) and (2), we get:

b₂ = 2b₁

Answer:

3:6

Step-by-step explanation:

8:24 and 24:72 reduce down to 1:3. 3:6 is 1:2.

The variance is 150.

We are given that the three bids are regarded as three independent random variables with a common uniform distribution on [0,10]. And we need to determine the variance of the accepted bid. The company agrees to accept the highest of three sealed bids on a property.

Hence, if X, Y, and Z represent the three independent random variables, the accepted bid is given byA = max (X,Y,Z)

We know that the variance of a uniform distribution on [0,10] is given byσ² = (b-a)²/12

Substituting a = 0, b = 10, we get σ² = 10²/12 = 25/3

Thus, the variance of each of X, Y, and Z is 25/3

Now, we need to find the variance of the accepted bid.

We can use the following formula to find the variance of a function of random variables: Var(g(X, Y, Z)) = E(g²(X, Y, Z)) - [E(g(X, Y, Z))]²

Since A = max (X,Y,Z), we haveA² = max (X,Y,Z)²

Using the identity,max (a,b)² = a² + b² - 2ab where a and b are any two real numbers, we haveA² = X² + Y² + Z² - 2XY - 2XZ - 2YZ

Thus, the variance of the accepted bid is given by Var(A) = E(A²) - [E(A)]²

Using the linearity of expectation, we haveE(A²) = E(X² + Y² + Z² - 2XY - 2XZ - 2YZ)E(X² + Y² + Z²) - 2E(XY) - 2E(XZ) - 2E(YZ)

Substituting E(X²) = E(Y²) = E(Z²) = 25/3 and E(XY) = E(XZ) = E(YZ) = 25/9, we getE(A²) = 3(25/3) - 2(25/9) = 50/3Also, E(A) = E(max (X,Y,Z))

Using the fact that the CDF of the maximum of two independent random variables is given by:

F_{max(X,Y)}(z) = F_X(z)F_Y(z)for all z, we haveF_A(z) = F_X(z)³ = z³/1000 since X, Y, and Z are identically distributed, and hence, have the same CDF.

Using this CDF, we can find the expected value of A by integrating z from 0 to 10:

E(A) = ∫₀¹₀ z(3z²/1000) dz= 3/400 ∫₀¹₀ z³ dz= 3/400 (10⁴/4)= 750/4

Hence,Var(A) = E(A²) - [E(A)]²= (50/3) - (750/4)²= (50/3) - 140625/16= [3200 - (7500/3)]/9= 150

Thus, the variance of the accepted bid is 150.

Therefore, the correct answer is 150.

Box B has the smaller range of masses, with a range of 49 grams, compared to Box A's range of 97,649 grams.

The question asks which of the boxes has the smaller range of masses and what is the value of this range in grams (g).
To find the range, we need to subtract the smallest value from the largest value in each box.
In Box A, the smallest value is 4 and the largest value is 97653. So, the range in Box A is 97653 - 4 = 97649 g.
In Box B, the smallest value is 2 and the largest value is 8762. However, we are given that key 35 represents a mass of 53 g and key 51 represents a mass of 51 g. So, the actual largest value in Box B is 51. Therefore, the range in Box B is 51 - 2 = 49 g.

Answer: To turn the expression -x^2 - 4x - 4 into an always true inequality, we need to find its vertex. The vertex is the point where the parabola changes direction and is given by x = -b/(2a) and y = f(-b/(2a)), where f(x) is the function in standard form, ax^2 + bx + c.

In this case, a = -1, b = -4, and c = -4, so the x-coordinate of the vertex is:

x = -(-4)/(2*(-1)) = 2

To determine whether the vertex is a maximum or minimum, we can look at the coefficient of x^2. Since a = -1, the parabola opens downward and the vertex is a maximum.

Therefore, we can write the inequality:

x^2 - 4x - 4 > -2

This is because the y-coordinate of the vertex is f(2) = -2, and the expression -x^2 - 4x - 4 is always less than -2 when x is not equal to 2. When x = 2, both sides of the inequality are equal.

So the inequality -x^2 - 4x - 4 > -2 is true for any value of x.

The two statements do not satisfy a valid deduction rule.

In this case, we are given two statements, p → (q ∨ r) and ¬ (p → q), and we need to construct a truth table for them. By analyzing the truth values of these statements, we will determine if they satisfy a valid deduction rule.

Truth Table for p → (q ∨ r):

To construct the truth table for p → (q ∨ r), we need to consider all possible combinations of truth values for the propositions p, q, and r. Since there are three propositions involved, there will be 2³ = 8 rows in the truth table.

To evaluate p → (q ∨ r), we consider the following rules:

If p is true (T) and (q ∨ r) is true (T), then p → (q ∨ r) is true (T).

If p is true (T) and (q ∨ r) is false (F), then p → (q ∨ r) is false (F).

If p is false (F), then p → (q ∨ r) is true (T) regardless of the truth value of (q ∨ r).

Now that we have the truth tables for p → (q ∨ r) and ¬ (p → q), we can analyze them to determine if the given deduction rule is valid.

The given deduction rule states that p → (q ∨ r) and ¬ (p → q) should have the same truth values for all combinations of truth values of p, q, and r.

Looking at the truth tables, we can see that there are instances where p → (q ∨ r) and ¬ (p → q) have different truth values. Specifically, when p is true (T) and q is false (F), the two statements have opposite truth values.

Since there are cases where the truth values differ, the given deduction rule is not valid.

Therefore, the two statements do not satisfy a valid deduction rule.

The maximum rate of change of the function at the point (3,1,1) is √478. 1. The direction in which the maximum rate of change of f(x, y, z) occurs is given by the gradient vector, which is the vector of partial derivatives with respect to x, y, and z. First, we compute the partial derivatives:

∂f/∂x = 2x*y^2*z
∂f/∂y = 2x^2*y*z + e^(y-z^2)
∂f/∂z = x^2*y^2 - 2z*e^(y-z^2)

At the point (3,1,1), the gradient vector is:

∇f(3,1,1) = (2*3*1^2*1, 2*3^2*1*1 + e^(1-1^2), 3^2*1^2 - 2*1*e^(1-1^2)) = (6, 19, 9)

So, the direction of maximum rate of change at the point (3,1,1) is given by the vector (6, 19, 9).

2. The maximum rate of change of the function at the point (3,1,1) is given by the magnitude of the gradient vector:

|∇f(3,1,1)| = sqrt(6^2 + 19^2 + 9^2) = sqrt(36 + 361 + 81) = sqrt(478)

When you multiply a negative number by another negative number, the result is always a positive number.

This rule is based on the properties of multiplication and the concept of negative numbers.

When two negatives are multiplied, the negative signs "cancel out" each other. Mathematically, if you have -a multiplied by -b, where a and b are positive values, the result is given by ab.

For example, if you multiply -2 by -3, the product is 6, which is a positive number. This can be explained by the idea that multiplying two numbers with opposite signs results in a negative product, while multiplying two numbers with the same sign (both negative) produces a positive product.

Therefore, when you multiply a negative by a negative, the outcome is a positive number.
