What is the box-and-whisker plot?A box and whisker plot displays a "box" with its left edge at Q₁, right edge at Q₃, "center" at Q₂ (the median), and "whiskers" at the maximum and minimum.
The box plot is also called box-and-whisker plot.
The data is divided into sections by box plots, with each section containing around 25% of the total data.
Box plots are useful as:
They offer a visual overview of the data,
making it simple for researchers to spot skewness,
the dispersion of the data set.
The minimum value, first quartile, median, third quartile, and maximum value are the five values that make up a box plot.
And they don't include mean.
From the above discussion,

What are Parallel Lines Cut by Transversal?
Straight, equally spaced lines that never cross each other and are on the same plane are called parallel lines. The angles that are created when any two parallel lines are intersected by a line (referred to as the transversal) have a relationship. Corresponding angles, Alternate Interior Angles, Alternate Exterior Angles, and Consecutive Interior Angles are some of the several pairs of angles that are created at this intersection.
Corresponding angles
When two parallel lines are intersected by a transversal, the corresponding angles have the same relative position
Alternate Interior Angles
Alternate interior angles are formed on the inside of two parallel lines which are intersected by a transversal.
Alternate Exterior Angles
The pairs of angles formed on either side of a transversal that divides two parallel lines are known as alternate exterior angles.
Consecutive Interior Angles
When two parallel lines are cut by a transversal, the pairs of angles formed on the inside of one side of the transversal are called consecutive interior angles or co-interior angles.

Jane is having difficulty deciding whether to put her savings in the Mystic Bank or in the Four Rivers Bank. Mystic offers a 12% rate compounded quarterly, and Four Rivers offers 14% compounded semiannually. Jane has $40,000 to invest and expects to withdraw the money at the end of five years. The better deal is:
Multiple Choice
Four Rivers because she will earn about $6,442 more.
Four Rivers because she will earn about $6,523 more.
Four Rivers because she will earn about $4,000 more.
Four Rivers because she will earn about $20,000 more.
Jane must therefore deposit her savings in the four rivers bank.
What is compound interest?Interest that is added to a loan and deposit sum is known as compound interest. In our everyday lives, it is the notion that is employed the most frequently. Compound interest is calculated as a sum using the interest and principal accrued over time. Compound interest versus simple interest differ primarily in this way.
As per the data provided in the question,
Rate, r = 12%
After five years, the total amount, if Jane had saved at Mystic Bank,if Jane had saved at Mystic Bank would be:
[tex]A = P(1+\frac{r}{100} )^n[/tex]
For compounded quarterly,
n = 5 × 4
n = 20
A = 40000(1 + 12/(4 × 100))²⁰
A = 72244.44 (i)
If Jane placed her savings with the Four Rivers, then,
A = 40000(1 + 14/(2 × 100))¹⁰
A = 40000 × 1.9671
A = 78686.054 (ii)
Therefore, it is evident that case (ii) is higher than case (i). Jane must therefore deposit her savings in the four rivers bank.

Answer:
To answer these questions, we need to first calculate the total number of payments you have made over the past 3 years. We can do this by multiplying the number of payments per year (12) by the number of years (3). This gives us a total of 36 payments.
Next, we can use a financial calculator or spreadsheet program to solve for the remaining balance on your loan after making 36 payments of $327.51 each. In a financial calculator, we can enter the following values:
N: 36
I: 5.8
PV: -14000
PMT: 327.51
FV: 0
Solving for PV gives us a remaining balance of $4,819.56. Therefore, the answer to part A is $4,819.56.
To find your equity in the car, we can subtract the remaining balance on the loan from the value of the car. In this case, your equity would be $7,500.00 - $4,819.56 = $2,680.44. Therefore, the answer to part B is $2,680.44.

The angle measures in this problem are given as follows:
7 - m < ADC = 82º.
8 - m < ADC = 44º.
How to obtain the angle measures?In item 7, the angle measure is found obtained the angle addition postulate, meaning that the measures are obtained as follows:
m<ADB = m < BDC + m < ADC.
Then the equation to find the value of x is obtained as follows:
144 = 7x + 34 + 9x + 46
16x = 64
x = 64/16
x = 4.
Then the angle ADC is obtained as follows:
m < ADC = 9(4) + 46 = 82º.
In item 8, the bisection means that the two angle measures are equal, hence the value of x is obtained as follows:
7x - 19 = 9x - 37
2x = 18
x = 18/2
x = 9.
m < ADC = 9(9) - 37 = 44º.

Five subtracted from the product of 6 and a number is at most -25.
The value of the number from the equation 6A - 5 ≤ -25 is A = -3.33
What is an Inequality Equation?
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the number be represented as A
Now , the value of A is calculated as

CAN SOMEONE HELP ME WITH ALGEBRA 2?
The solution set is for the given inequality is (-∞, -2.25]
How to solve the inequality?Here we want to solve the following inequality:
-11 - 8k ≥ 23 - (7 - 4k)
To solve this, we need to isolate the variable k in one side of the equation.
First we can expand the right side so we get:
-11 - 8k ≥ 23 - (7 - 4k)
-11 - 8k ≥ 23 - 7 + 4k
Group like terms:
-11 - 23 + 7 ≥ 4k + 8k
-34 + 7 ≥ 12k
-27 ≥ 12k
-27/12 ≥ k
-2.25 ≥ k
Then the solution is the set of all values smaller than or equal to -2.25, then the solution set is (-∞, -2.25]

Given f(x) = 3x - 5, find f(X - 2)
This question is about evaluating Functions.
Answers are
f(x- 2) = 3x - 7
f(x - 2) = x -7
f (x - 2) = 3x - 11
f(x - 2) = 3x² - 11x + 10
After evaluating f(x) = 3x - 5, the answer is f(x-2) = 3x - 11
What do you mean by functions?
A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). Expressions of well-known functions can be found in many frequently used mathematical formulas. A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X.
The set X is called the domain of the function and the set Y is called the codomain of the function.
Given function:
f(x) = 3x - 5
For f(x-2) substitute x as (x-2) in given function
f(x-2) = 3(x - 2) - 5 = 3x - 6 - 5 = 3x - 11
therefore, f(x-2) = 3x - 11
