The value of x is less than or equal to 2 and 1 half. The correct option is B.

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.

Given that inequality is 3¹/₂≥1.4x. The inequality will be solved as below,

3¹/₂ ≥ 1.4x

(14)/(10)x ≤ (5/2)

(5/10)x ≤  5/2

x ≤ (5/10) ÷ ( 5/2 )

x ≤ 2.5

x ≤ 2¹/₂

Therefore, the value of x is less than or equal to 2 and 1 half. The correct option is B.

How to arrange the card in the box?

Because there are four boxes and four cards, there are four ways to arrange the first card, three ways to arrange the second card (because one box is already occupied), two ways to arrange the third card, and one method to arrange the fourth card. As a result, the total number of possible ways to arrange the cards in the boxes is:

To calculate an augmented matrix, first write the coefficients of the variables in the equation in one matrix. Then, add the constants on the right side of the equation to the end of the matrix. This will form the augmented matrix.

An augmented matrix is a matrix composed of a coefficient matrix and a constant vector. It is used to represent a system of linear equations. To calculate an augmented matrix, first write the coefficients of the variables in the equation in one matrix. For example, in the equation 2x + 3y = 5, the coefficients are 2 and 3. The matrix would look like [2 3]. Then, add the constants on the right side of the equation to the end of the matrix. In this example, the constant is 5, so the augmented matrix would look like [2 3 5]. This augmented matrix can then be used to solve the linear equation. It can be used to row reduce the matrix to find the solutions of the variables, or it can be used with other methods such as Cramer's Rule or Gaussian Elimination.

Answer:

The profit/percent increase is $5.70

Step-by-step explanation:

If you bought the umbrella for $6.00 and sold the umbrella for $11.70 there is a $5.70 profit/percent increase because if you want to calculate a profit, then you have to subtract the number you sold the item for by how much you spent on the item, so $11.70 - $6.00 is $5.70.

The given vectors are: u = (20 + i, i, 2)v = (1 + i, 2, 41)The dot product of u and v is:u.v = (20 + i)(1 + i) + (i)(2) + (2)(41 - 1)= 20 + 20i + i + i² + 2i + 80= 101 + 22i

To find the imaginary part of u.v, we can simply extract the coefficient of i, which is 22. Hence, the imaginary part of u.v is 22. Therefore, the answer is rounded off to 22.00.

When considering two nonnegative numbers p and q such that p+q=6, the difference between the maximum and minimum of the quantity (p^2q^2)/2 is 81 - 0 = 81.

To find the maximum and minimum of the quantity (p^2q^2)/2, we can use the AM-GM inequality.
AM-GM inequality states that for any nonnegative numbers a and b, (a+b)/2 ≥ √(ab).

So, in our case, we can write:
(p^2q^2)/2 = (p*q)^2/2

Let x = p*q, then we have:
(p^2q^2)/2 = x^2/2
Since p and q are nonnegative, we have x = p*q ≥ 0.

Using the AM-GM inequality, we have:
(x + x)/2 ≥ √(x*x)
2x/2 ≥ x
x ≥ 0
So, the minimum value of (p^2q^2)/2 is 0.
To find the maximum value, we need to use the fact that p+q=6.

We can rewrite p+q as:
(p+q)^2 = p^2 + 2pq + q^2
36 = p^2 + 2pq + q^2
p^2q^2 = (36 - p^2 - q^2)^2

Substituting this into the expression for (p^2q^2)/2, we get:
(p^2q^2)/2 = (36 - p^2 - q^2)^2/2
To find the maximum value of this expression, we need to maximize (36 - p^2 - q^2)^2.

Since p and q are nonnegative and p+q=6, we have:
0 ≤ p, q ≤ 6
So, the maximum value of (36 - p^2 - q^2) occurs when p=q=3.

Thus, the maximum value of (p^2q^2)/2 is:
(36 - 3^2 - 3^2)^2/2 = 81

Therefore, the difference between the maximum and minimum of (p^2q^2)/2 is:
81 - 0 = 81.

The radius of the circle will be 4.6m.

What is area of a circle?

The measurement of the circle's boundaries is called as the circumference or perimeter of the circle. whereas the circumference of a circle determines the space it occupies. The circumference of a circle is its length when it is opened up and drawn as a straight line. Units like cm or unit m are typically used to measure it. The circle's radius is considered while calculating the circumference of the circle using the formula. As a result, in order to calculate the circle's perimeter, we must know the radius or diameter value. The area of the circle will be A = \(\pi r^{2}\).

The area of the circle given is = 15 m²

Sector of a circle with a central angle of 5π/11 rad

The area will be (1/2) * r² * Ф

15 = (1/2) * r² * (5π/11)

⇒r² = 30 * (11/5π)

⇒r² = 21.00

⇒r=4.6m

Step-by-step explanation:

the mix follows the ratio 2/3 (cups of cocoa to sugar).

2 × x = 6 cups

x = 6/2 = 3

so, the cocoa cups number is multiplied by the factor 3, and we need to multiply also the sugar cup number with the same factor to keep the ratio value unchanged :

so, we need 3×3 = 9 cups of sugar.

The linear expressions for the height and the width are (x + 3) and (x - 2), respectively.

To factor the polynomial -x^3 - x^2 + 6x, we can look for common factors and apply factoring techniques.

First, let's factor out -x to simplify the expression:

V(x) = -x(x^2 + x - 6)

Now, we need to factor the quadratic expression x^2 + x - 6. To do this, we look for two numbers that multiply to -6 and add up to +1 (the coefficient of the x term). The numbers that satisfy these conditions are +3 and -2.

Therefore, we can factor the quadratic as:

V(x) = -x(x + 3)(x - 2)

The factored form of the polynomial is -x(x + 3)(x - 2).

To determine the linear expressions for the height and the width, we can consider the factors:

Height: (x + 3)

Width: (x - 2)

Since the problem states that the height is greater than the width, we can assign the expressions accordingly:

Height = (x + 3)

Width = (x - 2)

Therefore, the linear expressions for the height and the width are (x + 3) and (x - 2), respectively.

The critical value of the correlation coefficient for a two-tailed test at alpha = 0.05 with a sample size of n = 23 is approximately plus/minus 0.497.

To understand why this is the case, we need to consider the distribution of the correlation coefficient, which follows a t-distribution. In a two-tailed test, we divide the significance level (alpha) equally between the two tails of the distribution. Since alpha = 0.05, we allocate 0.025 to each tail.

With a sample size of n = 23, we need to find the critical t-value that corresponds to a cumulative probability of 0.025 in both tails. Using a t-distribution table or statistical software, we find that the critical t-value is approximately 2.069.

Since the correlation coefficient is a standardized measure, we divide the critical t-value by the square root of the degrees of freedom, which is n - 2. In this case, n - 2 = 23 - 2 = 21.

Hence, the critical value of the correlation coefficient is approximately 2.069 / √21 ≈ 0.497.

Therefore, the correct answer is A. Plus/minus 0.497.

The absolute value equation |-7+y| = 13 has two solutions, y = 20 and y = -6, which satisfy the original equation and make the absolute value of -7+y equal to 13.

To solve the equation |-7+y| = 13, we consider two cases:

In this case, we add 7 to both sides of the equation:

-7+y+7 = 13+7

Simplifying, we have:

y = 20

Here, we simplify the expression inside the absolute value:

7-y = 13

To isolate y, we subtract 7 from both sides:

7-y-7 = 13-7

This gives:

-y = 6

To solve for y, we multiply both sides by -1 (remembering that multiplying by -1 reverses the inequality):

(-1)*(-y) = (-1)*6

y = -6

Therefore, the solutions to the equation |-7+y| = 13 are y = 20 and y = -6.
