Answer:
b. The number of digits in a randomly selected row until a 3 is found.
Explanation:
A random variable often used in statistics and probability, is a variable that has its possible values as numerical outcomes of a random experiment or phenomenon. It is usually denoted by a capital letter, such as X.
In statistics and probability, random variables are either continuous or discrete.
1. A continuous random variable is a variable that has its possible values as an infinite value, meaning it cannot be counted.
2. A discrete random variable is a variable that has its possible values as a finite value, meaning it can be counted.
Also, any random variable that meets certain conditions defined in a research study.
Hence, an example of a geometric random variables is the number of digits in a randomly selected row until a 3 is found.

Explanation:
Answer:
B. CH₅N
Explanation:
The combustion reaction of a compound CₐHₓNₙ with O₂ is:
CₐHₓNₙ + O₂ → a CO₂ + X/2 H₂O + n NO₂
Where 1 mole of CₐHₓNₙ with an excess of O₂ produce a moles of CO₂, X/2 moles of H₂O and n moles of NO₂
Thus, you need to convert the mass of CO₂ and H₂O to moles to find the C:H ratio and determine a possible empirical formula thus:
Moles CO₂ (Molar mass 44g/mol):
44g ₓ (1mol / 44g) = 1 mole CO₂ = 1 mole C
Mole of H₂O (Molar mass 18g/mol):
45g ₓ (1 mol / 18g) = 2.5 moles H₂O = 5 moles H
Thus, in the compound you have 5 moles of H per mole of C, and a possible empirical formula is:
B. CH₅N
The only structure that meet this C:H ratio
The two options would be to reduce the demand for energy and or use renewable sources of energy. Options C and D are correct.
<h3>How to reduce carbon emission</h3>
The burning of fossil fuels such as coal and crude oil-derived fuels generates a large amount of emissions.
In order to cut down on the emission, the demand for energy needs to be lowered by all means. In addition, instead of using fossil fuels, renewable sources of energy can be used.
Greenhouse gases such as carbon dioxide, oxides of sulfur, and water vapor are produced largely as by-products of burning fossil fuels. These gases form a layer in the atmosphere and trap reflected solar radiation.
By doing so, the increase the average annual temperature of the planet (global warming). The warming of the planet has several negative effects on the climate and the ecosystems as a whole.
Renewable sources of energy, on the other hand, have very little to no greenhouse gas emissions.
