The probability of event A or event B occurring, P(A or B), is 0.9 and d: 0.1125 is probability of A or B.

To find the probability of event A or event B occurring, we can use the formula:

P(A or B) = P(A) + P(B) - P(A and B)

Given that events A and B are mutually exclusive, it means that they cannot occur simultaneously. In this case, P(A and B) would be equal to 0 because the intersection of mutually exclusive events is empty.

Given:

P(A) = 0.75

P(B) = 0.15

Using the formula, we can calculate:

P(A or B) = P(A) + P(B) - P(A and B)

          = 0.75 + 0.15 - 0

          = 0.9

Therefore, the probability of event A or event B occurring, P(A or B), is 0.9.Among the provided answer choices, the correct answer is:

d: 0.1125

The first mathematician who came close to calculating pi was Archimedes of Syracuse.

In 250 BCE, he found the value of pi to be between 3.1408 and 3.1429 by inscribing and circumscribing a circle with polygons.

Pi is a mathematical constant that represents the ratio of the circumference of a circle to its diameter. Pi has an infinite number of decimal places and is commonly represented by the Greek letter π. It is approximately equal to 3.14159 but is an irrational number, meaning it cannot be expressed as a fraction of two integers.

Archimedes of Syracuse was a Greek mathematician, physicist, engineer, inventor, and astronomer who lived from 287-212 BCE. Archimedes is considered one of the greatest mathematicians in history and made significant contributions to mathematics, physics, engineering, and astronomy. He was also known for his inventions, including the Archimedes screw and the compound pulley system.

The number we need to multiply -16/7 to get -32/63 is 11.625. We'll use cross multiplication to find the number we need to multiply -16/7 by to get -32/63. Cross multiplication is a method for solving equations involving fractions.

The idea is to multiply both sides of the equation by a common denominator, so that the fractions become integers. Let's call the number we want to find "x". Then, we can write the equation as:

-16/7 * x = -32/63

Next, we'll multiply both sides of the equation by the least common multiple of the denominators, which in this case is 441. This will turn the fractions into integers by applying cross multiplication method.

-16 * 63 * x = -32 * 7 * 441

-1008 * x = -11712

Finally, to find the value of x, we'll divide both sides of the equation by -1008:

x = 11.625

So the number we need to multiply -16/7 to get -32/63 is 11.625.

The industry Lerner index is approximately 0.8113. This indicates that the industry has a moderate level of market power in setting prices for its goods.

The industry Lerner index measures the degree of market power that a firm has in setting prices for its goods. It is calculated as the difference between the price a firm charges and the marginal cost of producing an additional unit of output, divided by the price. The formula for the Lerner index is:
Lerner Index = (P - MC) / P

To find the industry Lerner index, we need to know the markup factor used to price goods. In this case, the industry suggests using a markup factor of 5.3.
Let's assume the marginal cost (MC) of producing a good is $10. Using the markup factor, we can calculate the price (P) as:
P = MC * Markup factor
P = $10 * 5.3
P = $53
Substituting these values into the Lerner index formula, we have:
Lerner Index = ($53 - $10) / $53
Lerner Index = $43 / $53
Lerner Index ≈ 0.8113

The boat is either about 2.334 miles or 2.666 miles from lighthouse B, depending on whether it sailed to the left or to the right of the line AB.

Let's draw a diagram to help visualize the problem. Let A and B be the positions of the lighthouses, and let C be the position of the boat after sailing 5 miles from A. Let x be the distance from C to B that we want to find, and let θ be the angle ACB.

Since the bearing of the boat from B is N65°E, we know that the angle ACB is (180° - 65°) = 115°. Also, since ACB is a straight line, we have

cos(115°) = x/8

Solving for x, we get

This condition alone does not guarantee that n is an absolute pseudoprime; it still needs to pass a prime number test while being composite.

An integer n of the form (6k+1)(12k+1)(18k+1) is said to be an absolute pseudoprime if all three factors are prime. This type of integer is interesting because it behaves like a prime number in some ways, even though it may not be prime.

To understand why this is the case, we need to look at the properties of absolute pseudoprimes. One important property is that if n is an absolute pseudoprime, then it passes the Miller-Rabin test for all bases up to log2(n). This means that it is very difficult to tell whether or not n is actually prime, since it behaves like a prime in terms of the Miller-Rabin test.

Another interesting property of absolute pseudoprimes is that they are related to the Fermat pseudoprimes. In particular, if n is an absolute pseudoprime, then it is also a Fermat pseudoprime to base 2.

Overall, absolute pseudoprimes are an intriguing mathematical concept that have many interesting properties. While they may not be prime, they behave like prime numbers in some important ways, making them a valuable tool for number theorists and mathematicians.
An integer n is an absolute pseudoprime if it is a composite number (non-prime) that passes the prime number test, such as the Fermat primality test. In the given expression, n = (6k + 1)(12k + 1)(18k + 1), n would be considered an absolute pseudoprime if all three factors (6k + 1, 12k + 1, and 18k + 1) are prime numbers.

How to get the product of the page

x * (x + 1) = 132

Expanding the equation, we get:

x² + x = 132

To solve for x, we need to rewrite the equation as a quadratic equation:

x²+ x - 132 = 0

Now, we can factor the quadratic equation:

(x - 11)(x + 12) = 0

This equation has two solutions for x:

x = 11

x = -12

Since page numbers cannot be negative, we discard the second solution. Thus, the left-hand page number is 11, and the right-hand page number is 11 + 1 = 12.

The value of x in the given 45-45-90 triangle is 9.89.

The given triangle is a right-angled triangle which can be solved using the Pythagoras theorem. The Pythagoras theorem states that the square of the hypotenuse is equal to the sum of the square of the base and the square of the perpendicular. This theorem can be applied to all right-angled triangles.

In the given triangle, we have been told that the length of both legs is 7. Now, after applying the theorem -

= 7²+7² = H²

= 49 + 49 = H²

= 98 = H²

= √98 = H

Answer:

The equation for the line is y = -2x+1

Step-by-step explanation:

The equation of a line is y=mx+b, where m is our slope, and b is our y-intercept (where the line crosses the vertical axis line).

To find our m we use rise over run (how far up it goes, divided by how far left or right it goes).

We see one point at (0,1) and another at (-3,7). Using rise over, we start at the first y point and count up. Our first y point is 1 (since the system is given by (x,y) ). Our second y point is 7. The difference between 1 and  (also known as 7-1 ) is 6 units.

Our first x point is 0 and our second y point is -3. The difference between -3 and 0 (also known as -3-0 ) is -3.

Now we put the change in x over the change in y to find the slope. It is (6/-3) also known as 6 divided by negative three which is equal to -2.

Out b is found easily and we just see where our line crosses the y-axis, which is at +1.

So we say m=-2, b=+1, therefore y=-2x+1
