Step-by-step explanation:
Researchers wanted to determine if there was an association between the level of trauma of an individual and their risk
of diabetes. The researchers studied 1544 people over the course of 12 years. During this 12-year period, they
interviewed the individuals and asked questions about their daily lives and the hassles they face. In addition,
hypothetical scenarios were presented to determine how each individual would handle the situation. These interviews
were videotaped and studied to assess the emotions of the individuals. The researchers also determined which
individuals in the study experienced any type of diabetes over the 12-year period. After their analysis, the researchers
concluded that the trauma-free individuals were less likely to experience diabetes. Complete parts (a) through (c).
(a) What type of observational study was this? Explain.
This was a
because information was collected about a group of individuals
The observational study is the Cross-sectional studies.
What is an observational study?It should be noted that an observational study is simply used to answer a research question that is based on what the researcher observes.
This is a cross-sectional studies because it analyzes a population of study at a specific point in time. It should be noted that this involves narrowing previously collected data to one point in time to test the prevalence of a theory.

Stop light A changes color every 45 seconds and Stop light B changes color every 80 seconds. Both Stop lights just changed. After how many seconds will the stoplights change color at the same time?
The stoplights will change color after 720 seconds. at the same time again.
Given: Stoplights A and B alternate between changing colors every 45 and 80 seconds, respectively.
One copy of each of the unique components and the common factor make up the Least Common Multiple (LCM).
The least common multiple of 45 and 80 is the amount of seconds before they change color simultaneously once more.
Since 80 = 5 x 2 x 2 x 2 and 45 = 5 x 3 x 3 respectively
A least common multiple of 45 and 80 is equal to 2x2x2x2x3x3x5 = 720.
Hence, the color of the spotlight will change after 720 seconds. at the same time again.

In a recent year, a university had an enrollment of 15,363 male and 19,512 female undergraduate students. The total number of full-time instructional faculty was 1,849. Find the ratio of students to full-time instructional faculty as a unit ratio. Round to the nearest whole number.
The required ratio of students to teachers is 19: 1.
Given that,
The total enrollment of male students and female students is 15,363 male and 19,512 female respectively.
The total number of full-time instructional faculty was 1,849.
To determine the ratio of students to teachers.
Here,
Total students = 15363 + 19512 = 34875
Number of teachers = 1849
Now,
Ratio = total students / teacher
Ratio = 34875 / 1849
Ratio = 19 : 1
Thus, the required ratio of students to teachers is 19 : 1.

A salesperson sold a pick-up for $18,760. They were paid a 4.5% commission. How much money were they paid?
the salesperson will be paid $ 844.2 for the one pickup they sell for $ 18,760 as 4.5 % commission is theirs.
We are given that the selling price of a pick up item is given as:
Selling price = $ 18,760
Now, it is also given that, on every sale, the salesperson gain a commission of 4.5 % as their pay.
The money they get paid for one pick up that they sell will be calculated by finding the percentage. So, we get that:
Money = 4.5 % of $ 18,760
Money = 4.5 / 100 × $ 18,760
Money = 0.045 × $ 18,760
Money = $ 844.2
Therefore, we get that, the salesperson will be paid $ 844.2 for the one pickup they sell for $ 18,760 as 4.5 % commission is theirs.

By using the concept of internal angles of a triangle, the solution of the system of linear equations related to the geometrical system is (x, y) = (40, 40).
What are the values of two variables associated with two angles from a right triangle?
In this system we have a geometrical system formed by two right triangles with a common hypotenuse. Right triangles are triangles where one of its internal angles are right angles and the sum of the measures of the internal angles within a triangle equals 180°. Then, this geometrical system can be modelled by using the following linear equations:
(x + 20) + 90 + 30 = 180 (1)
20 + 90 + (y + 30) = 180 (2)

A company makes pencils. they sell each pencil for $10.
Their revenue is represented by R= 10x
The cost to make the pencils is $3 each with a one time start up cost of $5000.
Their cost is represented by C= 3X+5000
1.Find the profit, P, (P=R-C) when the company sells 1000 pens.
2. Find the number of pens they need to sell to break even ( when R=C)
We have the profit fomula:
P = R - C
= $10.x - ($3.x + 1000)
= $7.x - 1000
1. If the company sells 1000 pens:
P = $7 . 1000 - $1000
= $6000
2. If they want to break even:
P at least = 0
Assume P = 0
=> $7.x - $1000 = 0
=> x = 1000/7 ≈ 142,86
So if they want to break even, they have to sell at least 143 pens

Rate of change = Which table shows a constant rate of change of –3? A 2-column table with 4 rows. Column 1 is labeled x with entries 3, 4, 5, 6. Column 2 is labeled y with entries negative 8, negative 5, negative 2, 1. A 2-column table with 4 rows. Column 1 is labeled x with entries 15, 16, 17, 18.

Column 1 is labeled x with entries negative 22, negative 21, negative 20, negative 19. Column 2 is labeled y with entries 2, negative 1, negative 4, negative 7.
Using the average rate of change concept, we have that:
The rate of the height is of 9.5 feet per minute.The table with a rate of -3 is given by: A 2-column table with 4 rows. Column 1 is labeled x with entries negative 22, negative 21, negative 20, negative 19. Column 2 is labeled y with entries 2, negative 1, negative 4, negative 7.What is the average rate of change of a function?The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:
[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]
For item 1, when the time in minutes changes by 1, the height changes by 9.5 units, hence the rate is given by:
r = 9.5/1 = 9.5 feet per minute.
For item 2, we want a table with a rate of -3, hence, when the first column changes by 1, the second column should always change by -3, hence the table is:
A 2-column table with 4 rows. Column 1 is labeled x with entries negative 22, negative 21, negative 20, negative 19. Column 2 is labeled y with entries 2, negative 1, negative 4, negative 7.

Therefore, the ratio of the number of laptops to total computers is 2:7
Number of laptops repaired by a technician = 18
Number of desktops repaired by a technician = 24
Total number of computers = no of laptops + no of desktops
= 18 + 24
= 42
We have to determine the ratio of laptops to total computers as
= no of laptops / total no of computers
= 18 / 42
= 6 / 14
= 2 / 7

What is the scale factor that was used to create WH
Answer:
The scale factor is 4/3
Step-by-step explanation:
Let x = the scale factor
15x = 20 Divide both sides by 15
x =20/15 Which simplifies to 4/3
The scale factor that was used to create WH will be 4/3.
What is the scale factor?The scale factor is defined as the proportion of the new image's size to that of the previous image decision-making. Dilation is the process of increasing the size of an object while maintaining its shape. Depending on the scale factor, the object's size can be increased or decreased.
Given that BF is dilated to create WH. The center of dilation is point A where BF=15, WH=20
The scale factor will be calculated as below:-
Let x = the scale factor
15x = 20
Divide both sides by 15
x =20/15
Which simplifies to 4/3.
x = 4 / 3

Find (F/G)(-3)
Value of (F/G)(-3) with the given functions F(x)=x² -19 and G(x) = 14 - x is equal to (-10/17).
As given,
Given functions
F(x)=x² -19
G(x)=14 - x
Substitute the values in the required function:
( F/G )(x)=( x² -19 )/( 14 - x)
Now substitute x= -3
( F/G )( -3) =[ (-3)² -19 ] /[ 14 - (-3) ]
⇒ ( F/G )(-3) =( 9-19) / (14+ 3)
