The cofactor of A is C = [-3 0; 0 -46], and the determinant of A is -3.

The cofactor of each element in a 2x2 matrix is found by switching the signs of the elements in the determinant when the sum is taken (i.e. changing the sign of one element in the determinant if it is in an odd-numbered row or column).

For a 2x2 matrix A = [a b; c d], the determinant is given by det(A) = ad - bc.

For the given matrix A = [1 1 47; 1 2 2; 2 5 1], the cofactor matrix C is found by finding the determinant of each 2x2 sub-matrix obtained by excluding one row and one column of A.

C = [(-1)(2-5) (1)(2-2); (1)(1-1) (-1)(1-47)].

C = [-3 0; 0 -46].

To find the determinant of A using the cofactor matrix C, we take the sum of the products of the elements in each row of A and the corresponding elements in each column of C.

det(A) = 1*-3 + 10 + 470 + 10 + 20 + 2*-46 = -3.

So the determinant of A is -3.

The total number of boys is 19, out of them 1 spring, 7 summers, 10 autumn leaves 1 to pick winter.

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

Given that there are 17 total summer lovers and 7 boys/summer, we know 10 girls like summer.

girls' summer then, so 10/2 is 5 girls' choice.

Since there are 17 total summer lovers and 7 boys/summer, we know 10 girls like summer and Two girls picked summer over spring,

so, 10/2 is 5 girls picking spring.

The last clue says that if you pick a spring lover, there is an 18.75% chance of it being a boy, so x/(x+5)=0.1875 x=1.

38% of interviewed students preferred summer, so: 17/x = 0.38 Total students= 45

We know that for every 8 guys, there are 11 girls.

So if we fiddle around with scaling that ratio to find the combination that adds up to 45, we get a scale of 2.35.

2.35*8=19 and 2.35*11=26

So the total number of girls is 26, meaning the number of girls/in autumn is 26-5-4-10=7

Three more boys chose autumn than the girls, so 10 boys/autumn.

Therefore, The total number of boys is 19, out of them 1 spring, 7 summers, 10 autumn leaves 1 to pick winter.

The equation of the ellipse with center (3,1), vertex (7,1), and focus (3+2√3,1) is (x - 3)² / 16 + (y - 1)² / 4 = 1.

To write the equation of the ellipse with the given center (3,1), vertex (7,1), and focus (3+2√3,1),  to determine some key properties of the ellipse.

Center (h, k) = (3, 1)

The center of the ellipse is (h, k) = (3, 1).

Major axis length = 2 × distance between center and vertex

The distance between the center and vertex is given by |3 - 7| = 4 units.

So, the major axis length is 2 × 4 = 8 units.

Distance between center and focus = c = |3 + 2√3 - 3| = 2√3 units

Now, we have all the information needed to write the equation of the ellipse in standard form:

(x - h)² / a² + (y - k)² / b² = 1

where (h, k) is the center of the ellipse, and a and b are the semi-major and semi-minor axes lengths, respectively.

Since the center is (3, 1),  (h, k) = (3, 1). We already know that the major axis length is 8 units, so a = 4.

To find b, we use the relationship between a, b, and c in an ellipse:

c² = a² - b²

(2√3)² = 4² - b²

4 × 3 = 16 - b²

12 = 16 - b²

b² = 16 - 12

b² = 4

b = 2

Now we have the values of a and b, so the equation of the ellipse is:

(x - 3)² / 4²+ (y - 1)² / 2² = 1

Simplifying further:

(x - 3)² / 16 + (y - 1)² / 4 = 1

Answer:

A. 15p+2 = 12p + 8 represents the problem, where p is the number of large pizzas.

To find the number of pizzas for which the cost is the same, you need to set the two expressions equal to each other and solve for p.

15p + 2 = 12p + 8

3p = 6

p = 2

So, the cost is the same when two large pizzas are ordered

The equation that represents the problem is D. 15+ 8p = 12 + 2p.

You can solve the equation to find out at which point the cost is the same by isolating the variable (p) on one side of the equation.

You can do that by subtracting 12 from both sides, and then subtracting 8p from both sides.

It will give you : 3 = 2p which means p = 1.5.

So, for 1.5 large pizzas the cost of ordering from Fast Delivery and Order for Home will be the same.

A) p → q is true because it states that if all elements in d satisfy the predicate p, then all elements in d also satisfy the predicate q.

p states that for all elements in d, if they satisfy the predicate p, then they must also satisfy the predicate q. q states that for all elements in d, if they satisfy the predicate p, then they must also satisfy the predicate q. Therefore, p → q is true, because it states that if all elements in d satisfy the predicate p, then all elements in d must also satisfy the predicate q. However, q → p is not necessarily true, because it states that if all elements in d satisfy the predicate q, then they must also satisfy the predicate p. This is not necessarily true, because some elements in d may satisfy the predicate q, but not satisfy the predicate p.

The inequality that can be used to find the possible length, x, Ricky could make his quilt is x > 8.

An inequality is a mathematical statement indicating the relative size or order of two values, where one value is not equal to the other. It uses symbols such as > (greater than), < (less than), ≥ (greater than or equal to), ≤ (less than or equal to), or ≠ (not equal to) to compare the values. The solution of an inequality is the set of values that make the inequality true.

Let x = length of the quilt

The quilt is a rectangle, hence the area of the quilt is equal to the product of the length and the width.

A = l x w

If the quilt is 7 feet wide and the area should be greater than 56 square feet, then we can write that as the inequality below.

Minimizing the Sum of Squared Deviations

In statistics, the objective of many analyses is to identify the values of parameters that minimize the sum of squared deviations between observed and expected values. A common example of this is finding the mean (average) of a set of values. In this context, the deviations are calculated as the difference between each observed value and the mean.

In the problem stated above, we have a sum of squared deviations given by the expression (x_1 - c)^2. The goal is to find the value of c that minimizes this expression. To do this, we will take the derivative of the expression with respect to c, set it equal to 0, and solve for c.

Taking the derivative with respect to c:

The derivative of (x_1 - c)^2 with respect to c is 2 * (x_1 - c) * (-1) = 2 * (c - x_1). Setting this equal to 0 and solving for c:

2 * (c - x_1) = 0

c = x_1

So, the value of c that minimizes the expression (x_1 - c)^2 is equal to x_1.

Comparing Sum(x_i - mu)^2 and Sum(x_i - x_1)^2:

Now, let's consider the two quantities Sum(x_i - mu)^2 and Sum(x_i - x_1)^2. Assuming that mu is the population mean and x_1 is a sample mean, we can say that Sum(x_i - mu)^2 will always be equal to or larger than Sum(x_i - x_1)^2. This is because the sample mean is an unbiased estimator of the population mean and has a smaller variance than the population mean. In other words, the sample mean will be closer to the observed values, on average, than the population mean, leading to smaller deviations and a smaller sum of squared deviations.

Assuming the length line is made of copper, the resistance would be 0.667.

The following formula can be used to determine the resistance of the diagonal line that passes through the corners of the 10mm by 10mm silicon integrated die: Resistance is equal to resistivity times length (cross-sectional area). The cross-sectional area of the line, which is 1 m thick and 5 m wide, may be calculated as 5 x 1 m = 5 m2. The Pythagorean Theorem, which asserts that the hypotenuse of a right triangle is equal to the square root of the sum of the squares of the other two sides, can be used to determine the length of the line. The line itself serves as the hypotenuse in this instance, while the other two sides measure 10 mm apiece. As a result, the square is equal to the length of the line.
