Trivia: Do You Think You Are Smarter Than A 6th Grader?

Explanation
The mean of a set of numbers is found by adding up all the numbers in the set and then dividing the sum by the total number of values. In this case, the sum of the numbers 2, 8, 9, 15, and 76 is 110. Dividing 110 by 5 (the total number of values) gives us a mean of 22. Therefore, the correct answer is 22.

Explanation
The question is asking for the factorial of C, which is represented by C!. The factorial of a number is the product of all positive integers less than or equal to that number. In this case, C is equal to 5, so 5! is calculated as 5 x 4 x 3 x 2 x 1, which equals 120. Therefore, the correct answer is 120.

Explanation
Extremophiles are organisms that thrive in extreme environments. These environments can include high temperatures, high pressures, acidic or alkaline conditions, or even extreme levels of radiation. Extremophiles have unique adaptations that allow them to survive and reproduce in these harsh conditions. They can be found in places such as deep-sea hydrothermal vents, hot springs, polar regions, and even inside rocks. Extremophiles have provided valuable insights into the limits of life on Earth and the potential for life to exist in extreme environments on other planets.

Explanation
The root word "therm" refers to heat.

Explanation
The probability of getting a multiple of four when rolling a die can be determined by finding the number of favorable outcomes (multiples of four) and dividing it by the total number of possible outcomes. In this case, there are two favorable outcomes (4 and 8) out of a total of six possible outcomes (1, 2, 3, 4, 5, 6). Therefore, the probability is 2/6, which simplifies to 1/3 or approximately 16.67%.

Explanation
When ice melts, it undergoes a phase change from a solid to a liquid state. However, the ice displaces the same volume of water as it melts, resulting in no change in the overall water level in the cup. Therefore, the water level remains the same.

Explanation
The highest amplitude is determined by the magnitude of the wave's displacement from its rest position. In this case, the given results show a range of displacements, with the highest being -20cm. This means that the wave reaches its furthest point below the rest position, resulting in a negative amplitude of 20cm.

Explanation
The distance between two successive crests of a wave is known as the wavelength. It represents the length of one complete wave cycle and is usually measured in meters or any other unit of length. The wavelength determines the characteristics of the wave, such as its frequency and energy.

Explanation
Rhyolite is an example of an igneous rock because it is formed from the solidification of magma or lava. Igneous rocks are created through the cooling and solidification of molten material. Rhyolite is a fine-grained igneous rock that is rich in silica and is typically formed from highly viscous lava. It is commonly found in volcanic areas and is characterized by its light color and high silica content. In contrast, iron ore, copper ore, and anthracite are not examples of igneous rocks as they are formed through different geological processes.

Explanation
John Jay is the correct answer because he was appointed as the first Chief Justice of the United States by President George Washington in 1789. He served in this position until 1795 and played a crucial role in establishing the authority and independence of the Supreme Court. Jay was also one of the authors of the Federalist Papers and had a significant impact on shaping early American jurisprudence.
