Samples versus population
a population is a composed of the entire group of people that could possibly be included in your study
population Generalization
the main purpose sampling quantitative research so that researchers so that generalize about the population and that means it is conducted
To find the volume of a cylinder you would multiply pi, radius squared, and height.
r= 6 ft
h= 2 ft
pi= 3.14
First you want to square your radius, so you would do 6 times 6.
This gives you 36.
Now you just multiply by 3.14 and get 113.04, then multiply that by 2.
Your final answer is 226.08ft³

Answer:
Credit remaining after 21 minutes = $30.4
Step-by-step explanation:
Credit remaining on a phone card is a linear function of the total calling time.
When graphed, let the linear function representing the line is,
y = mx + b
Where 'm' = slope of the line
b = y-intercept
From the graph,
Slope of the line = -0.12
y = -0.12x + b
If this line passes through a point (33, 28.96),
28.96 = -0.12(33) + b
b = 28.96 + 3.96
b = 32.92
Therefore, the linear function is,
f(x) = -0.12x + 32.92
where x = calling time
Credit left in the card after 21 minutes,
f(21) = -0.12(21) + 32.92
= -2.52 + 32.92
= $30.4
