What is an observational study?An observational study is a research method in which the researcher observes and records behavior or data without directly manipulating the variables.
We have,
In an observational study, the researcher simply observes and records data as it naturally occurs, without interfering or influencing the study participants.
This type of study is often used in social science research, as well as in medical research and epidemiology, to study the relationships between variables and to identify patterns or trends in the data.
Observational studies can be either cross-sectional, where data is collected at a single point in time, or longitudinal, where data is collected over an extended period of time.
In this case,
The researchers are simply observing and collecting data without actively manipulating any variables or performing any interventions.
Thus,
Having customers fill out a questionnaire about their favorite brand of toothpaste is an example of an observational study.

A.
0.03 second
B.
0.23 second
C.
0.11 second
D.
0.26 second
Answers
The difference between her best time and her worst time is equal to 0.26 seconds.
What is algebra ?
Algebra is a branch of mathematics that deals with various symbols and the arithmetic operations such as division , multiplication , etc.
Jodie has to swim for 100 meters. The four of her times to cover this distance are 22.98 seconds, 23.09 seconds, 23.06 seconds, 22.83 seconds.
Let's find the time per sec to swim at each instances.
So ,
100 meters in 22.98 seconds meant :
= 100 / 22.98
= 4.35 m/sec
Similarly ,
100 meters in 23.09 seconds meant :
= 4.33 m/sec
100 meters in 23.06 seconds meant :
= 4.34 m/sec
100 meters in 22.83 seconds meant :
= 100 / 22.83
= 4.38 m/sec
So , we can find out that Jodie swims distance of 100 meters fastest on speed of 4.38 m/sec in 22.83 seconds and slowest on speed of 4.33 m/sec in 23.09 seconds.
The difference between her best time and her worst time is :
= 23.09 - 22.83
= 0.26 seconds
Therefore , the difference between her best time and her worst time is equal to 0.26 seconds.

Cora ran 3 miles last week and will run 7 miles per week from now on. Hana ran 9 miles last week and will run 4 miles per week from now on.
In the answer box,
Write a system of equations to describe this scenario. Identify what the variables mean in the context of the problem.
Answers
Answer:
If Cora runs 1/2 mile per week and x is the number of weeks, then she will run 5+1/2x. Then determine how many weeks are in two and a half months (depends on which month it is as there are less weeks in February than in January!) but we could estimate 6.
For Hana, you will have 3+ 3/4 x
Step-by-step explanation:
First equation is y=5+1/2 x and then plug 6 in for x to solve for y. the second equation is y=3+3/4x and plug in 6.
The system of equations to describe this scenario are
y = 3 + 7xy = 9 + 4xThe variable x means the number of weeks they ran and the y variable means the total distance they covered in miles .
The situation can be modelled like a linear equation.
Therefore,
y = mx + b
where
m = slope
b = y-intercept
Cora race will be as follows:
y = 3 + 7xHana race will be as follows:
y = 9 + 4xThe variable x which is the independent variable is the number of weeks each of them ran in the equation.
The variable y which is the dependent variable is the total distance covered in miles.

Tim has a bag of 36 orange-flavoured sweets and Peter has a bag of 44 grape-flavoured sweets. They have to divide up the sweets into small trays with equal number of sweets; each tray containing either orange-flavoured or grape-flavoured sweets only. If there is no remainder, find the largest possible number of sweets in each tray.
Answers
Answer:
the largest possible number for each would be dividing it by two so 36 divided by two is 18 and 44 divided by two is 22
so for the orange the largest number would be 18
and for the grape the largest number would be 22

Step-by-step explanation:
M*thway is a pathway to many abilities some considered to be... unnatural
Statement (C) the y-intercept is y=-1 describes the graph of the function.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
[tex]\rm f(x) = \dfrac{x^2-1}{x^2-2x+1}[/tex]
The above function is a rational function.
The denominator cannot be zero
x² - 2x + 1 ≠ 0
(x - 1)²≠ 1
x ≠ 1
To find y-intercept plug x = 0
f(0) = -1
Thus, statement (C) the y-intercept is y=-1 describes the graph of the function.

Explanation:
Erase everything but lines p, q, and s. Also, we'll keep angles 6 and 16 as well. Check out the diagram below.
As you can see from the diagram, lines p and q act like the parallel lines. Imagine we can shift line p to make it horizontal so it's parallel to line q. This might help show that angles 6 and 16 are same side exterior angles.
Note: Because line p is not parallel to line q, this means angles 6 and 16 are not supplementary (they don't add to 180).

The system of equations that represents the situation is yx = y.

The system is yx = y, since the amount of dollars per hour multiplied by the amount of hours, plus any amount (if needed) will equal the total amount of money that Jada and/or Andre receives.

Graph 5. weak negative correlation
Step-by-step explanation:
If i'm wrong PLEASE correct me
The graph first is perfect negative correlation, graph second is the modest negative correlation.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]
As we know, the coefficient of correlation varies between -1 and +1.
If r = +1 (means the relation between the variable is strong and positive)
If r = -1 (means the relation between the variable is strong but negative)
As we can see in the graph, the line goes down represents the negative correlation and the line goes up represents the positive correlation.
So, we can say:
The first graph is perfect negative correlation.
The second graph is modest negative correlation.
The third graph is modest positive correlation.
The fourth graph is strong positive correlation.
The fifth graph is weak negative correlation.
Thus, the graph first is perfect negative correlation, graph second is the modest negative correlation.
