how many ways are there to select 11 countries in the united nations to serve on a council if 1 is selected from a block of 50, 2 are selected from a block of 70 and 8 are selected from the remaining 69 countries?

The formula that can be used to represent this function is N*L^2 = k

The number of animal species, N, is inversely proportional to the square of the body length, L. Therefore, the formula representing the function would be:

N = k/L^2

Where k is the proportionality constant. It represents the relationship between N and L^2, and it is a constant value.

The above formula can also be written as

N*L^2 = k

It means that the product of N and L^2 is constant.

It can be derived by assuming that there is some proportionality constant k such that N=k/L^2 and then testing this relationship against data on animal species and body lengths.

To find the solution to the equation 4(q + 56.5) = 30q - 112, we can start by isolating the variable on one side of the equation.

First, we'll distribute the 4 on the left side:

4q + 4(56.5) = 30q - 112

4q + 226 = 30q - 112

Now we'll subtract 4q from both sides:

226 = 26q - 112

Next, we'll add 112 to both sides:

338 = 26q

Finally, we'll divide both sides by 26 to find the value of q:

q = 13

So the solution to the equation 4(q + 56.5) = 30q - 112 is q = 13.

Answer:

q=13

Cramer’s rule is the direct method for solving simultaneous algebraic equations.

Because polynomials are included on both sides of the equal sign, algebraic equations are sometimes referred to as polynomial equations. Variables, coefficients, constants, and algebraic operations like addition, subtraction, multiplication, division, and exponentiation are all components of an algebraic equation.

One of the key techniques for solving a system of equations is Cramer's rule. In this approach, determinants of matrices are used to compute the values of the system's variables. Cramer's rule is frequently referred to as the determinant technique as a result.

Deb had 2 3/4 pounds of blueberries. Deb let her friend clarence eat 1/4 of the blueberries. Clarence ate 0.6875 pounds of blueberries.

To find out how many pounds of blueberries Clarence ate, we need to first convert the 2 3/4 pounds to a decimal. We can do this by dividing the numerator (3) by the denominator (4) and adding the result to the whole number (2).

2 3/4 pounds = 2 + (3/4) = 2 + 0.75 = 2.75 pounds

Now we know that Deb had 2.75 pounds of blueberries. To find out how many pounds of blueberries Clarence ate, we need to multiply this amount by the fraction of blueberries he ate (1/4).

2.75 pounds x 1/4 = 0.6875 pounds

So Clarence ate 0.6875 pounds of blueberries.

The value of x is 55 degrees.

If two lines are parallel and intersected by a transversal, then the consecutive interior angles formed are supplementary, meaning they add up to 180 degrees.

Since we know that m∠A + m∠B = 180 and we know that m∠A = x, we can use this information to find the value of x.

m∠A + m∠B = 180

x + (x+70) = 180

x + x + 70 = 180

2x = 110

Yes.The equation y = -3 represents a line that is parallel to the x-axis.

In a two-dimensional coordinate system, the x-axis is the horizontal axis and the y-axis is the vertical axis. A line parallel to the x-axis will have a constant y-value, and a line parallel to the y-axis will have a constant x-value.

In this case, the equation y = -3 represents a line that has a constant y-value of -3. This means that for every point on the line, the y-coordinate will be -3 and the x-coordinate can take any value. This line is parallel to the x-axis as it does not change in its x-coordinate, so it does not have a slope and it's equation is a horizontal line.

Note, a line parallel to the x-axis is also called a horizontal line, and a line parallel to the y-axis is also called a vertical line.

The remainder is 2 when x⁴ + x³ - 2x² + x + 1 is divided by x - 1.

The given polynomial is x⁴ + x³ - 2x² + x + 1.

The given divisor is x - 1

First we choose a term to multiply with the first term of the divisor such that we get the first term of the polynomial.

(x)(x^3) = x^4

Thus, we multiply the divisor (x - 1) by x^3 which gives x^4 - x^2.

Now we subtract this from the polynomial which gives 2x^3 - 2x^2 + x + 1.

Next we multiply the divisor by 2x^2 which gives 2x^3 - 2x^2. Again we subtract the same from the remaining polynomial 2x^3 - 2x^2 + x + 1 and get x + 1.

Repeating the same we multiply the divisor by 1 which gives x - 1. Subtracting the same from the remaining polynomial x + 1 we get the remainder 2.

There are 2 pounds of apples Hannah buy for the cost for her purchase to be the same from both stores.

Given that;

At Giant Eagle, a box of cereal costs $2.89 and apples cost $1.29 per pound.

And, At Shop & Save, the apples are $1.05 per pound and a box of

cereal is $3.37.

Now,

Let number of pounds of apples can Hannah buy for the cost for her purchase to be the same from both stores = x

So, We can formulate;

For, At Giant Eagle, a box of cereal costs $2.89 and apples cost $1.29 per pound.

The total cost is,

⇒ $2.89 + $1.29x

And, For Shop & Save, the apples are $1.05 per pound and a box of

cereal is $3.37.

Total cost is,

⇒ $3.37 + $1.05x

Now, We can equate both the equation to find the number of pounds of apple to buy.

⇒ $3.37 + $1.05x = $2.89 + $1.29x

⇒ 3.37 + 1.05x = 2.89 + 1.29x

⇒ 3.37 - 2.89 = 1.29x - 1.05x

⇒ 0.48 = 0.24x

For the first trial, we are 95% confident the true proportion of wins with the new game strategy is between 0.560 and 0.620. For the second trial, we are 95% confident the true proportion of wins with the new game strategy is between 0.610 and 0.670.

In which the variables used to calculated these bounds are listed as follows:

n is the sample size.

The confidence level is of 95%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.

The complete solution to this problem is: x = 1.8, y = 3.

Equations can be used to represent relationships between variables and to solve problems. They are written using an equal sign (=) and can include numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division.

For example, the equation 2x + 3 = 7 is an equation that states that the expression on the left side (2x + 3) is equal to the expression on the right side (7). The goal is to find the value of the variable x that satisfies the equation. In this case, x = 2 is a solution to the equation.

To find the value of x for which the pair of numbers (x; 3) would be a solution to the equation 10x - y = 15, we need to substitute the value of y with 3 and solve for x. So, we have:

10x - 3 = 15

Next, we can add 3 to both sides to isolate x:

10x = 18

Finally, we can divide both sides by 10 to find x:

x = 1.8

So, for the pair of numbers (x; 3) to be a solution to the equation 10x - y = 15, x must be equal to 1.8.

At the point of tangency, the tangent line (or segment, or ray) is perpendicular to the circle's radius.

In geometry, the straight line that "just touches" the curve at a particular position is known as the tangent line to a plane curve at that location. According to Leibniz, it is the path connecting two points on a curve that are infinitely close to one another. 

A tangent line is a simple straight line that only touches a function once. (See atop.) The instantaneous rate of change of the function at that specific position is shown by the tangent line. The derivative of the function at a location on the function is equal to the slope of the tangent line at that point (See below.)
