The answer to your question is BOTH A AND B
The random variable W is Normal, with a mean of 45 ounces and a standard deviation of three ounces.
<h3>How to describe the random variable?</h3>
The given parameters are:
- Sample size, n = 9
- Population mean, μ = 5 ounces
- Standard deviation, σ = 1 ounce
The mean of the 9 apples is:
μ = 5 ounces * 9
This gives
μ = 45 ounces
The variance of the 9 apples is:
σ² = 1 ounces * 9
This gives
σ² = 9 ounces
Take the square root of both sides, to calculate the standard deviation.
σ = 3 ounces
Since, the variable W is normal; the description of the variable W is (b)

Answer:
The first wave of the Industrial Revolution lasted from the late 1700s to the mid-1800s. It industrialized the manufacture of textiles and began the move of production from homes to factories. Steam power and the cotton gin played an important role in this period

Reformers challenged the authority of the pope and the clergymen as well as challenging the church with scholarly debates instead of believing in the absolute truth of belief and faith
Explanation:
The best analogy that suggests that electrons moves round the nucleus in an atom is the Bohr model.
According to Neil Bohr;
- Based on Rutherford's model, he suggested that the extranuclear part consists of electrons.
- These electrons are in spherical orbits called shells or energy levels around the nucleus.
- The nucleus is the tiny massive center of the atom.
- Electrons can undergo transitions from one level to another.
