This quiz consists of five open-ended questions related to Mathematics. Read each question carefully and try to answer as accurately as possible.

- What is the Pythagorean Theorem, and how is it used?
- How is the quadratic formula used to solve a quadratic equation?
- Define the term "slope" and provide an example of how it can be calculated.
- What is the difference between a permutation and a combination, and how do you calculate each one?
- If a clock shows a time of 3:45, what is the angle between the hour and minute hands?

- The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. It is used to solve for the length of a missing side in a right triangle, given the lengths of the other two sides.
- The quadratic formula is used to solve quadratic equations of the form ax^2 + bx + c = 0. It is written as x = (-b ± sqrt(b^2 - 4ac)) / 2a and provides the solutions for the equation.
- The slope of a line is a measure of how steep it is and is defined as the change in y divided by the change in x between any two points on the line. For example, the slope of a line passing through the points (2, 5) and (4, 9) can be calculated as (9-5) / (4-2) = 2.
- Permutations and combinations are ways of counting the number of possible arrangements or selections of a given number of objects. Permutations count arrangements where the order matters, such as arranging a group of people in a specific order. Combinations count selections where the order does not matter, such as choosing a group of people to form a committee. The formula for permutations is n! / (n-r)! and the formula for combinations is n! / (r!(n-r)!), where n is the total number of objects and r is the number to be selected.
- The hour hand moves 30 degrees in an hour and 7.5 degrees in 15 minutes, while the minute hand moves 6 degrees in a minute. In this case, the hour hand is at 3, which is 90 degrees from the 12 o'clock position. The minute hand is at the 9 o'clock position, which is 135 degrees from the 12 o'clock position. Therefore, the angle between the two hands can be calculated as 135 - 90 - (7.5/2) = 67.5 degrees.
