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.
According to Ohm's law, Voltage divided by "Current" is equal to resistance.
R = V / I

Explanation:
1: This idiom is a descendant of the above. It chiefly means to go to bed in the sense of stopping the activity one has been doing for the night. (I'll answer all correctly if you mark me "brainlist", notify me if you choose.)
The weight percent is of caffiene is 7.98%.
There are several ways of expressing concentration in chemistry. One of the methods of expressing concentration is by the use of percentage.
In this case, we want to obtain the percent weight/weight concentration of caffeine in benzene.
From the question, we can see that;
Mass of solute = 6.5 g
Mass of solvent = 75 g
percent w/w = mass of solute/ mass of solute + mass of solvent × 100/1
percent weight of caffeine=
6.5/6.5 + 75 × 100/1 =7.98%

Answer: 10
Explanation:
When the number removed, the mean change from 12 to 11, so we assume that the removed number, x, has related to the median.
To find the removed number x, we sat their average equal to 11.
(12 + x) /2 = 11
12 + x = 22
x = 10
