population screening of risky alcohol and drug use via internet and interactive voice response (ivr): a feasibility and psychometric study in a random sample
Answers
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.

JJill begins the summer with $500 in her savings account. Each week, she withdraws $20. Her brother, Sam,starts the summer with $150 in his account. He adds $30 to his account each week. At what week will both Jill and Sam have the same amount in their account.
Answers
Answer:
7th week
Step-by-step explanation:
Let us represent the number of weeks as x
Jill begins the summer with $500 in her savings account. Each week, she withdraws $20.
$500 - $20× x
500 - 20x
Her brother, Sam,starts the summer with $150 in his account. He adds $30 to his account each week.
$150 + $30 × x
150 + 30x
At what week will both Jill and Sam have the same amount in their account?
We solve this be Equating both Equations together
Jill = Sam
500 - 20x = 150 + 30x
Collect like terms
500 - 150 = 30x + 20x
350 = 50x
Divide both sides by 50
50x/50 = 350/50
x = 7 weeks
Therefore, at the 7 week, Jill and sam would have the same amount in their accounts

The amount of interest earned for both investments was $550. Let x represent the amount of money invested in the first account and y represent the amount of money invested in the second account. Which system of equations best represents the situation?
Answers
Answer:
The system of equations best represents the situation
x + y = 17,000.... Equation 1
0.025x + 0.065y = 550... Equation 2
Step-by-step explanation:
Let
x represent the amount of money invested in the first account and
y represent the amount of money invested in the second account.
We are told that:
Tyrone had $17,000 to invest.
Hence,
x + y = $17,000
x + y = 17,000..... Equation 1
We also known that:
He invested part of that amount at 2.5% annual interest for one year and the other part at 6.5% annual interest for one year. The amount of interest earned for both investments was $550
The formula for Interest =
Principal(Amount invested) × Rate × Time.
Hence:
25% × x + 6.5% × y = 550
0.025x + 0.065y = 550... Equation 2
The system of equations best represents the situation
x + y = 17,000.... Equation 1
0.025x + 0.065y = 550... Equation 2

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.

A 48000 gallon water tank is being filled at a rate of 40 gallons per minute. At this rate, how many minutes will it take to fill this tank 3/5 full?
Answers
The minutes it will take for the tank to be 3/5 full is 720 minutes.
When the tank be 3/5 full?A fraction is a non-integer that is made up of a numerator and a denominator. The numerator is the number above and the denominator is the number below. An example of a fraction is 3/5.
The first step is to determine how many gallons the tank would have when it is 3/5 full. To determine this value, multiply the volume of the tank by 3/5.
Gallons when the tank is 3/5 full = 3/5 x 48,000 = 28,800
Now, divide the speed of the water by the gallons in the tank when it is 3/5 full.
28,800 / 40 = 720 minutes

Answers
Answer:
2.40G + 1.20C ≤15
Step-by-step explanation:
The inequality function is
Given that
The cost of goat milk for each liter is $2.40 = G
And, the cost of the cow milk for each liter is $1.20 = C
Now the equation would be
2.40g + 1.20c
Now this must be lower or equal than $15
So, the inequality function would be
2.40G + 1.20C ≤15
hence, the inequality function is 2.40G + 1.20C ≤15
Answer:
2.4G + 1.2C < or = to 15

I need help plsssss ...... name the transversal that connects them and classify the angle pair
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).

which algebraic equation represents the words: forty percent of mrs. garcia's score is 400 points. what is mrs. garcia's score?
Answers
The algebraic equation "0.40x = 400" represents the words: forty percent of Mrs. Garcia's score is 400 points. Mrs. Garcia's score is 1000.
Algebraic equation is an equation made up of variables and coefficients that can be used to solve mathematical problems or questions.
To formulate an algebraic equation, we designate a variable for unknown values.
Mrs. Garcia's score is unknown, and so
let x = Mrs. Garcia's score
Based on the information given on the problem, forty percent of Mrs. Garcia's score is 400 points. Forty percent can be written as 0.40.
40% of x is 400
0.40x = 400
Hence, the algebraic equation for that is 0.40x = 400.
Evaluating the value of x,
0.40x = 400
x = 400 / 0.40
x = 1000
Therefore, Mrs. Garcia's score is 1000.

In the given statement is :
When the least common multiple of two positive integers is divided by their greatest common divisor, the result is 33. If one integer is 45.
To find what is the smallest possible value of the other integer
Now, According to the question
One of the numbers 3 ×3× 5 = 45
The lowest common multiple has to be a multiple of 45 i.e.,
3 ×3× 5 something when LCM is divided by the greatest common divisor
then the answer is 33 = 3 x 11 .
So the other number will have to be a multiple of 11
3 ×3× 5× 11 × ?/ some factor of 4 = 33
(3 ×5) ×3× 11 × 1 /3 × 5 = 33
