Data of different sizes can be easily arranged with histograms, but not with stem-and-leaf diagrams. This is a drawback.
What are Stem-and-leaf charts?Stem-and-leaf charts often include the original data values while histograms do not. This is a crucial advantage the former has over the latter.
The primary benefit of stem-and-leaf charts over histograms is that they display the original data values.
In contrast to stem-and-leaf charts, which lack this capability, histograms make it straightforward to organize data of various sizes. This is a serious disadvantage.

Find two functions f and g such that f(g(x))=x for all real numbers x .
The functions are f(x) = 5x-1 and g(x) = [tex]\frac{x+1}{5}[/tex].
We have to find two functions such that their composition gives the identity function.
That is, we need to find functions f and g such that f(g(x)) = x.
Also f(g(x)) = (f o g)(x)
A function g is said to be the inverse of a function f if, (f o g)(x) = f(g(x)) = x, for all real numbers x.
So in short if we take f(x) any function then we should find its inverse function.
Let f(x) = 5x - 1.
Then take y = 5x - 1.
⇒ x = [tex]\frac{y+1}{5}[/tex]
That is if we take g(x) = [tex]\frac{x+1}{5}[/tex], then,
f(g(x)) = f([tex]\frac{x+1}{5}[/tex]) = 5([tex]\frac{x+1}{5}[/tex]) - 1 = x

The bag that has the lowest unit price per pound is the 5 pound bag.
How to find the unit price ?Unit price is the value of a single unit of measure.
A 3-pound bag of apples costs $3.94, and a 5-pound bag costs $5.92.
Let's find the unit price per pounds of each products to know the lowest.
Therefore,
unit price per pound for the 3 pound bag = 3.94 / 3
unit price per pound for the 3 pound bag = 1.31333333333
unit price per pound for the 3 pound bag = $1.313 per pound
unit price per pound for the 5 pound bag = 5.92 / 5

Using a linear function, it is found that 1466 gallons of water were in the tank when jabria began adding water.
What is Mathematical function ?
Function is defined as the expression or relation between any given two variables such as x and y and there must be an independent variable and dependent variable.
A linear function is modeled by: y = mx + b
where,
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, we have given that in 12 minutes, the amount of water increased by 3456 gallons, hence the slope is given by :
m = 3456/12 = 288.
In 7 minutes, the tank contained 3,482 gallons of water, hence the initial amount was given by :
3482 - 7 x 288 = 1466

g (x) = x ² - 3 x + 2
The question states to find the division of the function f, that is, f (x) = x - 2, and function g, that is, g (x) = x ² - 3 x + 2
Performing the division operation on these functions is just like simple division.
This implies, dividing the two functions f (x) and g (x), we get
g (x) / f (x) = x² - 3x + 2 / x - 2
