Choose 3 people from 7: C(7, 3) = 35. The remaining 4 can be divided into 2 groups in 2 ways. Total = 35 * 2 = 70.

The word 'BOOK' has 4 letters with 'O' repeating. The number of arrangements is 4! / 2! = 12.

The word 'LEVEL' has 5 letters with 'L' and 'E' repeating. The arrangements = 5! / (2! * 2!) = 30.

The word 'SCHOOL' has 6 letters with 'O' repeating 2 times. The arrangements are 6! / 2! = 360.

Using the formula A = P(1 + r)^n, we set 3P = P(1 + 0.1)^n. Solving gives n ≈ 12 years.

Using the formula A = P(1 + r)^n, we set A = 3P and solve for n, which gives approximately 12 years.

A person with blue eyes must have the genotype bb, as blue is recessive.

A fallacy is an error in reasoning that renders an argument invalid, often leading to incorrect conclusions.

Precision refers to the consistency of repeated measurements, regardless of their accuracy.

In Mendel's experiments, yellow seed color was observed to be the dominant trait in pea plants.

In Mendel's experiments, yellow seed color was observed to be dominant over green seed color.

An anemometer is a device used to measure wind speed.

An 'isobar' is a line on a weather map that connects points of equal atmospheric pressure.

Topology is the branch of mathematics that studies the properties of space that are preserved under continuous transformations.

Linear algebra is important as it deals with vector spaces and linear mappings, which are foundational in various applications across mathematics and science.

Topology is the branch of mathematics that studies the properties of space that are preserved under continuous transformations.

The multiplicative inverse of 3 mod 11 is 4, since 3 * 4 ≡ 12 ≡ 1 (mod 11).

The multiplicative inverse of 3 mod 11 is 4, since (3 * 4) mod 11 = 12 mod 11 = 1.

All operations (addition, subtraction, multiplication) are valid in modular arithmetic.

For any integer a, a mod 2 will always yield either 0 or 1, depending on whether a is even or odd.

For any integer k, k mod k = 0, as k is divisible by itself.

According to the Aufbau principle, the σ2s orbital is filled first before any other orbitals.

In O2, the π2p orbitals are the highest energy orbitals.

The energy levels of molecular orbitals can vary depending on the specific atoms and their electronegativities.

The mass difference in nuclear fission is converted into kinetic energy of the fission fragments, according to Einstein's equation E=mc².

The mass difference in nuclear fission is referred to as the mass defect, which is converted into energy according to Einstein's equation E=mc².

Nuclear fission releases neutrons along with a significant amount of energy.
