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.
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
Jodie is on the swim team. Below are four of her times swimming 100 meters.
22.98 seconds, 23.09 seconds, 23.06 seconds, 22.83 seconds
What is the difference between her best time and her worst time?
A.
0.03 second
B.
0.23 second
C.
0.11 second
D.
0.26 second
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.

population screening of risky alcohol and drug use via internet and interactive voice response (ivr): a feasibility and psychometric study in a random sample
There were substantial differences in alcohol and drug usage by the manner of administration, however, problem drinking and drug use were present in 21.1% and 2.8% of the group, respectively.
What do you mean by population screening of risky alcohol and drug?The topic of whether data from population surveys could be gathered more quickly and affordably than using paper questionnaires is brought up by the widespread accessibility of computer-based technologies like the Internet and Interactive Voice Response (IVR) systems. The issue extends to whether it is possible to assess the prevalence of such behaviors in the general population when dealing with potentially stigmatized behaviors like problematic alcohol and drug use without endangering the accuracy of the findings. This study evaluates the reliability, response rate, and problematic alcohol and drug use of the Internet and IVR versions of the AUDIT and DUDIT. Randomly chosen from the Swedish general population, 5000 people were contacted by mail and asked to respond to the AUDIT and DUDIT questionnaires online or over the phone.

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.
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.

Step-by-step explanation:
8 - 6r + 3 = 5
Combine like terms

Subtract 5 from both sides
6 - 6r = 0
Add 6r to both sides
6 = 6r

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.

Answers:
The transversal line is line s
The angles 6 and 16 are same side exterior angles
=================================================
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).
