If there are 133,758 cases of AIDS, 22,293 were probably infected as teenagers.
What do you mean by research paper?A research paper is a written work that presents the results of original research or provides an in-depth analysis of a particular topic or issue. Research papers are typically written by scholars, academics, or students, and are commonly submitted as part of a course assignment, a doctoral or master's degree requirement, or for publication in a scholarly journal.
A research paper typically includes several key elements: an introduction that provides background information on the topic and sets the stage for the rest of the paper; a literature review that summarizes existing research on the topic; the methodology section that describes the methods used to conduct the research; the results section that presents the findings of the research; and a discussion or conclusion section that interprets the results and places them in the context of the broader field of study.
The writing style of a research paper is usually formal and objective, with a focus on clearly and accurately communicating the results of the research. Research papers often include citations and references to other works, which demonstrate the writer's familiarity with the literature and support the validity of their findings.
If 1/6 of the people with AIDS are in their 20s, then 1/6 of 133,758 cases is 133,758 / 6 = 22,293 cases.
These 22,293 people with AIDS in their 20s were probably infected as teenagers, so the answer is 22, 293 cases were probably infected as teenagers.

X+3x-4=10-3 Solve the following equation. Be sure to show all steps. x + 3x - 4 = 10 - 3x
x = 2 is the solution of the given equation: x + 3x - 4 = 10 - 3x
What is an equation?The meaning of such an equations in algebra is just a mathematical expression stating the equality between two mathematical terms. For instance, 6x + 5 = 11 is an equation where 6x + 5 and 11 are two expressions separated by the 'equal' sign.
Identity equations and conditional equations are the two types of equations. For just any value of both the variables, an equality remains true. Only such variables have values that make a condition expression true. Two expressions joined by an equals sign ("=") form an equation.
x + 3x - 4 = 10 - 3x
or, 4x - 4 = 10 - 3x
or, 4x + 3x = 10 + 4
or, 7x = 14

How to represent a linear equation?To represent a straight line on a graph consider two points namely x and y intercepts of the line. To find x-intercept put y = 0 and for y-intercept put x = 0. Then draw a line passing through these two points.
The parameters are;
Suppose the year 2020 represents x = 0.
The distance travelled per year can be taken as the slope of the linear equation. Thus, slope = 19000.
And, the distance travelled by January 1, 2020 is 41000.
This tells us that for x = 0, y = 41000.
The linear equation in slope intercept form is given as;
y = mx + c
where;
m is slope
c is y-intercept
Substitute the corresponding values in the above equation to obtain,
y = 19000x + c
At x = 0, y = 41000
41000 = (19000 × 0) + c

What are the six trigonometric ratios?Trigonometric ratios for a right angled triangle are from the perspective of a particular non-right angle.
In a right angled triangle, two such angles are there which are not right angled(not of 90 degrees).
The slant side is called hypotenuse.
From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called base.
From that angle (suppose its measure is θ),
[tex]\sin(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of Hypotenuse}}\\\cos(\theta) = \dfrac{\text{Length of Base }}{\text{Length of Hypotenuse}}\\\\\tan(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of base}}\\\\\cot(\theta) = \dfrac{\text{Length of base}}{\text{Length of perpendicular}}\\\\\sec(\theta) = \dfrac{\text{Length of Hypotenuse}}{\text{Length of base}}\\\\\csc(\theta) = \dfrac{\text{Length of Hypotenuse}}{\text{Length of perpendicular}}\\[/tex]
Given;
Height=[tex]2\sqrt{11}[/tex]
Base= 10
Hypotenuse= 12
Now,
sin M= 2[tex]\sqrt{11}[/tex]/12
=[tex]\sqrt{11}[/tex]/6
cos M= 10/12
=5/6
tan M= 2[tex]\sqrt{11}[/tex]/10

Relative frequency can be defined as the number of times an event occurs divided by the total number of events occurring in a given scenario.
To calculate the relative frequency two things must be known:
Number of total events/trials
Frequency count for a category/subgroup.
Relative frequency = subgroup frequency/ Total frequency
Cumulative frequency-
In statistics, the frequency of the first-class interval is added to the frequency of the second class, and this sum is added to the third class and so on. Frequencies that are obtained this way are known as cumulative frequency (c.f.).
Now,
For Relative frequency

In triangle IJK , O is the intersection of the three medians . If IN = 12 find IK. please help
Since it is stated that O is the centroid (also known as the point of intersection of the three medians), the segment JN, which traverses a triangle's vertex, would have to be a median to segment IK. IK = 24
What is meant by median?When a data set's median value is used, 50% of the data points in the collection have values that are lower or equal to the median and 50% of them have values that are higher or equal to the median. When working with a small data collection, you must first count the number of data points (n) and organize them in ascending order. Sorting all of the data points and selecting the center one yields the median, or middle number (or if there are two middle numbers, taking the mean of those two numbers).Example: The number 4 is the median of the numbers 4, 1, and 7 since it is in the middle when the numbers are ordered (1, 4, 7).As a segment is divided into two congruent pieces by medians, IN = NK = 12 since IN = 12.
IK is the sum of the measure of IN and NK, so in other words:
IK = IN + NK = 12 + 12 = 24

In triangle IJK, O is the intersection of the three medians. If IN = 12 then the value of IK is 24.
What is a median?A triangle's median is a line segment that connects a vertex to the middle of the side directly across from it.
Given that, O is the intersection of the three medians. Then, the segment JN which passes through a vertex of the triangle, would have to be a median to segment IK.
A median divides the segment into two equal parts. Thus, median JN divides the segment IK into two equal parts.
Thus, IN = NK
The value of IN = 12, hence NK = 12.
The value of IK is:
IK = IN + NK = 12 + 12 = 24
