False. The intercepted arc is actually twice the measure of the inscribed angle only if the inscribed angle is an angle at the center. If the inscribed angle is not at the center, the intercepted arc will have a different measure.

So, in general, the relationship between the measure of the intercepted arc and the inscribed angle it was created from depends on the location of the inscribed angle in the circle. This is a long answer, but it provides a detailed explanation of the relationship between the intercepted arc and the inscribed angle in different scenarios.

AN intercepted arc is twice the measure of the inscribed angle it was created from.
In a circle, when an inscribed angle is formed by two chords, it intercepts an arc on the circle. According to the Inscribed Angle Theorem, the measure of the inscribed angle is half the measure of the intercepted arc. Therefore, the intercepted arc is indeed twice the measure of the inscribed angle.

The probability of getting a subject who is not diabetic, given that the test result is negative, is approximately 0.1786.

To find the probability of getting a subject who is not diabetic, given that the test result is negative, we can use the data provided in the table. From the table, we can see that out of the total subjects tested, 5 are not diabetic and have a negative test result. The total number of subjects with a negative test result is 28.

To calculate the probability, we divide the number of subjects who are not diabetic and have a negative test result (5) by the total number of subjects with a negative test result (28).

Probability = Number of subjects who are not diabetic and have a negative test result / Total number of subjects with a negative test result

Probability = 5 / 28

Simplifying this fraction, we get:

Probability ≈ 0.1786

Therefore, the probability of getting a subject who is not diabetic, given that the test result is negative, is approximately 0.1786.

The equation of a line perpendicular to  y = x - 9 and passes through (-7, 1) is y = - x - 6

The equation of a line can be represented in a point slope form as follows:

y - y₁ = m(x - x₁)

where

Therefore, the line is perpendicular to  y = x - 9 and passes through (-7, 1).

Perpendicular lines follows the rule:

m₁ m₂ = -1

1m₂ = -1

m₂ = -1

Hence, let's find the y-intercept of the equation of the lines using (-7, 1)

y = - x + b

The final result of the expression c(a + b)(a - b)  is ca^2 - cb^2.

Using the distributive property, we can expand the expression as follows:

c(a + b)(a - b) = ca(a - b) + cb(a - b)

Then, using the distributive property again, we can simplify each term:

ca(a - b) = ca^2 - cab

cb(a - b) = -cb^2 + cab

Putting the terms together, we get:

c(a + b)(a - b) = ca^2 - cab - cb^2 + cab

The terms cab and -cab cancel each other out, leaving us with:

c(a + b)(a - b) = ca^2 - cb^2

The equations with parentheses added to make them true are;

Parentheses indicate that operations within it should be completed first before those that are outside the parentheses.

The given terms of the equations can be regrouped with parentheses to make the equations true as follows;

1. 4 × 3 + 7 - 6 × 1 + 4 = 20

The above equation gives;

3 + 7 - 6 = 4

Therefore;

4 × 3 + 7 - 6 × 1 + 4 = 4 × (3 + 7 - 6) × 1 + 4

4 × (3 + 7 - 6) × 1 + 4 = (4 × 4) × 1 + 4

(4 × 4) × 1 + 4 = 16 × 1 + 4 = 16 + 4 = 20

Which gives;

2. 60 - 18 ÷ 2 + 4 + 10 ÷ 2 = 12

60 - 18 = 42

2 + 4 = 6

The first four terms, therefore gives;

(60 - 18) ÷ (2 + 4) = 7

10÷2 = 5

Which gives;

60 - 18 ÷ 2 + 4 + 10 ÷ 2 = (60 - 18) ÷ (2 + 4) + 10÷2

(60 - 18) ÷ (2 + 4) + (10÷2) = 7 + 5 = 12

Which gives;

60 - 18 ÷ 2 + 4 + 10 ÷ 2 = (60 - 18) ÷ (2 + 4) + 10÷2 = 12

The expression is therefore;

3. 80 - 36 ÷ 2 + 6 - 2 × 5 + 1 = 44

80 - 36 ÷ 2 + 6 - 2 × 5 + 1 = 80 - 36 ÷ (2 + 6 - 2) × (5 + 1)

(2 + 6 - 2) = 6, and (5 + 1) = 6

Therefore;

80 - 36 ÷ 2 + 6 - 2 × 5 + 1 = 80 - ((36 ÷ 6) × 6)

80 - ((36 ÷ 6) × 6) = 80 - ((36 × 6) ÷ 6)

80 - ((36 × 6) ÷ 6) = 80 - (36 × 1) = 44

Therefore;

4. 3 × 5 + 4 - 2 × 2 + 6 - 4 = 15

3 × 5 + 4 - 2 × 2 + 6 - 4 = 3 × (5 + 4) - (2 × (2 + 6) - 4)

3 × (5 + 4) - (2 × (2 + 6) - 4) = 3 × 9 - (16 - 4)

3 × 9 - (16 - 4) = 27 - 12 = 15

To prove that A* search always finds the optimal goal, we need to show that it satisfies two properties 1. Completeness: A* search is guaranteed to find a solution if one exists. 2. Optimality: If a solution is found by A* search, it is guaranteed to be the optimal solution.

1. Completeness:

  To prove completeness, we need to show that A* search is guaranteed to find a solution if one exists.

  A* search explores the search space by expanding nodes based on the estimated cost of reaching the goal, which is determined by the heuristic function. The heuristic function used in A* search is admissible, meaning it never overestimates the actual cost to reach the goal.

  A* search maintains a priority queue of nodes to be expanded, and it always selects the node with the lowest estimated cost (f-value) to expand next. Since the heuristic is admissible, the f-value of the goal node will never decrease as we explore the search space.

  If a solution exists, A* search will eventually reach the goal node because it explores nodes in order of increasing estimated cost. Once the goal node is reached, A* search will terminate and return the solution. Therefore, A* search is complete.

2. Optimality:

  To prove optimality, we need to show that if a solution is found by A* search, it is guaranteed to be the optimal solution.

  Suppose there exists an optimal solution that is different from the one found by A* search. Let's assume this alternative solution has a lower cost than the one found by A* search.

  Since the heuristic function used in A* search is admissible, it never overestimates the actual cost to reach the goal. This implies that the estimated cost (h-value) of any node in the search space is less than or equal to the actual cost (g-value) of reaching the goal from that node.

  Now, consider the node in the alternative solution where it deviates from the path found by A* search. This node must have a lower estimated cost (h-value) than the corresponding node in the A* search path because the alternative solution has a lower overall cost.

  However, since A* search always selects the node with the lowest estimated cost (f-value) to expand next, it would have chosen the node in the alternative solution before the corresponding node in the A* search path. This contradicts our assumption that the alternative solution has a lower cost.

  Therefore, we can conclude that if a solution is found by A* search, it is guaranteed to be the optimal solution.

By establishing both the completeness and optimality properties of A* search, we have shown that A* search always finds the optimal goal.

To maximize profits, the firm should produce a quantity of goods x = 5 and y = 10, based on the cost function and price constraints.

To maximize profits, the firm needs to find the quantities of goods x and y that will yield the highest profit. The profit function can be defined as the revenue minus the cost. Revenue is calculated by multiplying the quantity of each good produced with their respective prices, while the cost function is given as C(x, y) = 10x + xy + 10y.

The firm is committed to delivering a total of 15 units, which can be expressed as x + y = 15. To determine the optimal production quantities, we need to maximize the profit function subject to this constraint.

By substituting the price expressions Ps = 50 - x + y and Py = 50 - x + y into the profit function, we obtain the profit equation. To find the maximum profit, we can take the partial derivatives of the profit equation with respect to x and y, set them equal to zero, and solve the resulting system of equations.

Solving the equations, we find that the optimal production quantities are x = 5 and y = 10, which maximize the firm's profits.

The radius of the circle can be determined using the Pythagorean theorem. Since the chord is 5 units away from the center of the circle, a right triangle can be formed where one leg is half the length of the chord (5 units) and the hypotenuse is the radius of the circle. Using the Pythagorean theorem, we can solve for the radius as follows:

r^2 = (10/2)^2 + 5^2

r^2 = 25 + 25

r^2 = 50

r = sqrt(50) = 5sqrt(2) units

Therefore, the radius of the circle is 5sqrt(2) units.

To further explain, the Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. In this case, the chord is a line segment connecting two points on the circle and is perpendicular to the radius passing through the midpoint of the chord. Since the chord is 10 units long and 5 units away from the center of the circle, the length of one leg of the right triangle is 5 units (half the length of the chord), and the length of the other leg is the radius of the circle. Using the Pythagorean theorem, we can solve for the unknown length of the radius.
