The simplified form of A + 1 1/6 = -11 7/9 is \(A = - 12\frac{17}{18}\)

and, the letter A in algebra is  any variables of real numbers.

Simplified form:

Fractions are not integers, but numbers between integers. He is part of the whole. Fractions also have two parts - a numerator and a denominator. We get fractions in their simplest form when the numerator and denominator can no longer individually be reduced to a lower number.

Now,

a + \(1 \frac{1}{6}\) = \(-11 \frac{7}{9}\)

convert the mixed to improper fraction number:

\(1 \frac{1}{6} = \frac{7}{6}\)

This implies:

\(A+ \frac{7}{6} = -11 \frac{7}{9}\)

Convert the mixed to improper fraction number:

\(-11 \frac{7}{9} = \frac{106}{9}\)

This implies:

\(A+ \frac{7}{6} = \frac{106}{9}\)

Move 7/6 in the right side,

therefore,

   A = -106/9 - 7/6

⇒ A = -233/18

convert the mixed to improper fraction number:

\(\frac{233}{18} = 12\frac{17}{18}\)

Therefore, we get:

A =   \(- 12\frac{17}{18}\)

Adding the expression 20x^2 + 11xy + 10y^2 to 23x^2 - 11xy + 15y^2 will give us 22xy - 3x^2 - 5y^2.

To determine what should be added to 23x^2 - 11xy + 15y^2 to get 22xy - 3x^2 - 5y^2, we need to rearrange the terms so that like terms are grouped together.

Starting with 23x^2 - 11xy + 15y^2, we can rearrange the terms by adding and subtracting 22xy - 3x^2 - 5y^2 as follows:

(23x^2 - 11xy + 15y^2) + (22xy - 3x^2 - 5y^2) = (23x^2 - 3x^2) + (-11xy + 22xy) + (15y^2 - 5y^2)

Simplifying the expression in parentheses, we get:

(23x^2 - 3x^2) = 20x^2

(-11xy + 22xy) = 11xy

(15y^2 - 5y^2) = 10y^2

In general, to add two polynomial expressions, we need to combine like terms by adding or subtracting the coefficients of the same variables. By rearranging the terms, we can identify the like terms and add or subtract them accordingly.

The percentage of the original area of wetlands currently left in the United States is approximately 50%.

Wetlands are regions of land where the soil is continually or intermittently soaked with water. Wetlands have a particular hydrology, soil, and vegetation mix that results in specialised ecosystems that offer a variety of ecological functions.

There are many different types of habitats where wetlands can be found, such as coastal locations, interior regions, and high-altitude mountain regions. They come in a variety of shapes, such as marshes, swamps, bogs, fens, and estuaries, and can be freshwater, brackish, or saline.

Wetlands are significant for several reasons. For species, such as migrating birds, amphibians, and fish, they offer crucial habitats. They also aid in removing contaminants from water, lessen the effects of flooding, and give people access to recreational activities. Wetlands are crucial for carbon sequestration as well.

When subtracting a positive rational number from a negative rational number, the difference will be negative.

This is because subtracting a positive number is equivalent to adding its additive inverse, and the additive inverse of a positive number is negative.

In rational arithmetic, a negative rational number is represented as a fraction with a negative numerator and a positive denominator. Similarly, a positive rational number has a positive numerator and a positive denominator. When subtracting a positive rational number from a negative rational number, we are essentially combining these two numbers.

The subtraction process involves finding a common denominator for the two rational numbers and then subtracting their numerators while keeping the denominator the same. Since the negative rational number has a negative numerator, subtracting a positive rational number from it will result in a negative difference.

For example, if we subtract 2/3 from -5/4, the common denominator is 12. The calculation would be (-5/4) - (2/3) = -15/12 - 8/12 = -23/12, which is a negative rational number.

Therefore, when subtracting a positive rational number from a negative rational number, the difference will be a negative rational number.

To conduct a follow-up study that would provide 95% confidence that the point estimate is correct to within +0.08 of the population proportion, the required sample size can be calculated using the formula:

n = [(z^2 * p * q) / E^2]

Where:

z = z-score corresponding to the desired confidence level (1.96 for 95% confidence level)

p = point estimate of the population proportion (0.43 in this case)

q = 1 - p

E = acceptable sampling error (0.08 in this case)

Substituting the values, we get:

n = [(1.96^2 * 0.43 * 0.57) / 0.08^2] = 148.15

Rounding up to the nearest integer, we get a required sample size of 148 consumers.

To conduct a follow-up study that would provide 99% confidence that the point estimate is correct to within +0.08 of the population proportion, we need to use a z-score of 2.58 (corresponding to 99% confidence level) in the formula. Substituting the values, we get:

n = [(2.58^2 * 0.43 * 0.57) / 0.08^2] = 266.85

Rounding up to the nearest integer, we get a required sample size of 267 consumers.

To conduct a follow-up study that would provide 95% confidence that the point estimate is correct to within +0.02 of the population proportion, we need to use the same formula with a different value of E. Substituting the values, we get:

n = [(1.96^2 * 0.43 * 0.57) / 0.02^2] = 1,462.41

Rounding up to the nearest integer, we get a required sample size of 1,463 consumers.

To conduct a follow-up study that would provide 99% confidence that the point estimate is correct to within +0.02 of the population proportion, we need to use a z-score of 2.58 in the formula. Substituting the values, we get:

n = [(2.58^2 * 0.43 * 0.57) / 0.02^2] = 6,614.51

Rounding up to the nearest integer, we get a required sample size of 6,615 consumers. The sample size requirements increase as the desired confidence level increases or as the acceptable sampling error decreases. This means that a larger sample size is needed to achieve a higher level of confidence or a smaller margin of error. For example, increasing the desired confidence level from 95% to 99% or decreasing the acceptable sampling error from 0.08 to 0.02 will result in a significant increase in the required sample size. Therefore, researchers need to carefully balance the trade-offs between the desired level of confidence, the acceptable sampling error, and the available resources (time, budget, etc.) to determine an appropriate sample size for their study.

\(\displaystyle\\Answer:\ -\frac{14}{13} x+y=\frac{8}{13}\)

Step-by-step explanation:

Ax+By=C   the slope is 14/13   (5,6)    (-8,-8)

The slope m equil 14/13

\(\displaystyle\\By=mx+C\\\\By=\frac{14}{13} x+C\ \ \ \ (1)\)

Substitute the coordinates of the points into equation (1) and obtain a system of equations:

\(\displaystyle\\\left \{ {{B(6)=\frac{14}{13}(5)+C } \atop {B(-8)=\frac{14}{13}(-8)+C }} \right.\\\\\left \{ {{6B=\frac{70}{13} +C\ \ \ \ \ \ \ (2)} \atop {-8B=-\frac{112}{13}+C\ \ \ (3) }} \right.\)

Multiply  both parts of the equation (3) by -1:

\(\displaystyle\\\left \{ {{6B=\frac{70}{13}+C \ \ \ \ (4)} \atop {8B=\frac{112}{13}-C }} \right.\)

Add these equations :

\(14B=\frac{182}{14}\\\\ 14B=14\)

Divide both parts of the equation by 14:

\(B=1\)

Hence, let's substitute the value of B into equation (4):

\(\displaystyle\\6(1)=\frac{70}{13}+C \\\\6=\frac{70}{13}+C\\6-\frac{70}{13} =\frac{70}{13} +C-\frac{70}{13}\\\\\frac{6*13-70}{13}=C\\\\\frac{78-70}{13}=C\\\\\frac{8}{13}=C\\\)

\(\displaystyle\\Thus,\ C=\frac{8}{13}\\\\ So,\ 1(y)=\frac{14}{13} x+\frac{8}{13} \\ -\frac{14}{13} x+y=\frac{8}{13}\)

There are 35 possible designs for the printed circuit board with four different components placed on it, assuming each of the seven locations can hold only one component.

To calculate the number of possible designs for the printed circuit board with seven locations for component placement, we can use the combination formula.

The number of combinations of r items from a set of n items is given by the formula:

nCr = n!/r!(n-r)!

In this case, we want to find the number of combinations of four components from seven locations. Thus, we can calculate it as follows:

7C4 = 7!/4!(7-4)! = (7x6x5)/(3x2x1) = 35

Therefore, there are 35 possible designs for the printed circuit board with four different components placed on it, assuming each of the seven locations can hold only one component.

Using separation of variables technique, the solution for the given differential equation is OE. Inly-91-4x-8.

The differential equation to solve is:

y' = (4x - y) / 3y

First, we can factor out the 3y from the denominator to get:

y' = (4x - y) / (3y)

Next, we can multiply both sides by y to get:

y y' = 4x - y

Now, we can separate the variables by dividing both sides by (4x - y) y:

dy / (4x - y) = dx / y

Integrating both sides, we get:

ln|4x - y| = ln|y| + C

where C is the constant of integration. We can simplify this to:

ln|4x - y| - ln|y| = C

ln|4x / y - 1| = C

Taking the exponential of both sides, we get:

4x / y - 1 = e^C

Solving for y, we get:

y = 4x / (1 + Ce^x)

To find the constant of integration C, we can use the initial condition y(2) = 10. Substituting x = 2 and y = 10 into the solution, we get:

10 = 8 / (1 + Ce^2)

Solving for C, we get:

C = (8 / 10) - e^4

C = -0.2212

Substituting this value of C into the solution, we get:

y = 4x / (1 - 0.2212e^x)

Simplifying, we get:

y = 4x / (0.7788e^-x - 1)

Thus, the answer is (OE) Inly-91-4x-8.
